Hands-On learning with the Apollo in Austria

Posted By: Vlado Vancura 232 Views 0 Comment

As part of the LIFEApollo2020 project, several engaging workshops were held across Austrian schools this year to introduce students to the Apollo butterfly (Parnassius apollo) and its importance in maintaining healthy ecosystems. Through hands-on activities and the creation of a dedicated Apollo garden, students learned about the unique needs of this species and how conservation efforts can protect it.

School Workshops: Interactive learning is fun!

In Spring, the austrian project team, together with butterfly expert Otto Feldner, organized engaging workshops in Austrian schools to introduce students to the captivating life of the Apollo butterfly. Each workshop began with an interactive overview of the Apollo butterfly’s lifecycle, guiding students through each stage from egg to caterpillar, pupa, and finally, the adult butterfly. By exploring the specific needs of the Apollo butterfly at each stage we aimed for students to develop a deeper respect for its lifecycle and understand the importance of habitat preservation. They learned about the butterfly’s reliance on specific feeding plants, with adult butterflies (imagines) depending on nectar sources like pincushion flowers, knapweeds and thistle, while caterpillars (larvae) feed exclusively on Sedum species such as Sedum album, Sedum sexangulare, or Sedum telephium maximum. Without these plants, it wouldn’t be possible to maintain the delicate balance essential for the Apollo butterfly’s survival.

Through lectures and followed up group and individual works, students explored the concept of an “Umbrella species” and how conserving a single species, like Parnassius apollo, can have widespread benefits for its entire ecosystem. An umbrella species is one whose protection indirectly shields many other species within the same habitat. Since the Apollo butterfly has very specific habitat and dietary needs, ensuring that its environment remains intact requires maintaining a rich diversity of native plants, clean soil, minimal human disturbance and polution levels. This, in turn, creates a suitable habitat for countless other organisms that share the same space. This learning experience not only educated students on butterfly conservation but also hopefully deepened their appreciation for the interconnectedness of nature.

The Apollo Garden: Building a conservation space together

In collaboration with students, an Apollo Garden was established at a school in Mittersill, Austria, as part of the LIFEApollo2020 project. This garden serves as a dedicated small-scale habitat for Apollo butterflies and other pollinators, allowing students to actively participate in conservation. Together, they designed and created a vibrant space, carefully planting Sedum species essential for caterpillars, as well as seeds of a variety of nectar-rich flowers like pincushion flowers, thistles, and field scabious, which provide food for adult butterflies. The garden also includes stones and sunlit areas, mimicking the natural rocky habitats that Apollo butterflies prefer.

Students and teachers learned practical gardening techniques to make environments more butterfly-friendly, such as selecting the right plants, ensuring good soil conditions, and creating sheltering spots. Creating the Apollo Garden allowed students to experience how conservation can begin in their own community. They learned that even small gardens can act as “stepping stones” for butterflies and other pollinators, aiding in migration and enhancing local biodiversity.

Gardens for Apollo: Something for Butterflies, Caterpillars, and People

Posted By: Kamila Redererova 236 Views 0 Comment , ,

One of the key activities of the Apollo 2020 project, “Conservation of Parnassius apollo in Poland, Czechia, and Austria,” is creating habitats for butterflies and offering educational activities. This led to the idea of establishing Gardens for Apollo. These gardens are special spaces where we plant nectar-rich flowers for butterflies and host plants for Apollo caterpillars.

Each garden is built with the direct involvement of local site hosts, guided by our experts. Before any planting begins, we organize educational talks and workshops for both adults and children. Some gardens, especially smaller ones, focus more on education. For instance, school gardens highlight how changing garden management can attract pollinators. These small spaces also create conditions that support the growth of Parnassius apollo populations as individuals reintroduced nearby spread into these gardens.

Meanwhile, some larger Gardens for Apollo are designed as habitats where future butterfly reintroductions are planned. All of these gardens are located within the project’s activity area, known as the Land of the Apollo. This region is becoming known for not only its natural connection to the species but also its cultural significance, thanks to the project’s efforts.

This year, we’ve created four new Gardens for Apollo and revisited one established in 2023. Our garden season began in April with a visit to the Arts and Crafts School Complex in Jelenia Góra. Despite late sowing in June, we were pleased to find that the plants had germinated and spread. Together with the students, we sowed more seeds and installed a sign with information about the garden and the project. We hope the meadow continues to grow and becomes a feeding ground for many pollinators.

In May, we planted two Gardens for Apollo near the Ecocentre in Uniemyśl. At the Tatra Glamp camping site in Okrzeszyn, we talked about the Apollo butterfly and its habitat, and introduced our citizen science campaign, “Where is the Big White Butterfly?”. With the help of campsite guests and local residents, we prepared the ground, planted Sedum, and sowed seeds of meadow plants. We’re excited to continue working with them to expand nature education in the area.

Later in May, we participated in the annual Upper Lusatian Houses Open Day, where we organized a fair of local handicrafts and products. Alongside the visitors, we planted another Garden for Apollo at a small market near the local inn.

In between these activities, we also visited Primary School No. 1 in Kamienna Góra. The students there helped us create a Sedum “roundabout,” designed to gradually transform the school lawn into a flowering meadow. Working with these energetic children was both fun and productive!

Our biggest challenge came with the Garden for Apollo at the Parada Three Cultures House in Niedamirów. The venue’s beautiful setting and supportive atmosphere made it a fantastic event. Together with the team from the Karkonosze National Park, we held a family-friendly festival that included lectures, workshops, and, of course, gardening. We planted 10 acres of butterfly-friendly plants, and in the autumn, we’ll create a habitat using limestone aggregate and more Sedum. We’ll always remember that day and the inspiring conversations we had with participants. Next year, we hope the Apollo butterfly will visit Niedamirów and enjoy the garden as much as we did!

Looking ahead, we’re already brainstorming ideas for next year’s Gardens for Apollo. If you’re active or live in the Western Sudeten region and would like to start a garden with us, we’d love to hear from you!

Summary of Apollo EduActivities in Austria 2023

Posted By: Kamila Redererova 522 Views 0 Comment

The LIFEApollo2020 project includes educational activities aiming at raising awareness about the need of preserving the Parnassius apollo butterfly. This species serves as an umbrella species, meaning its well-being reflects the overall health of its habitat. By focusing on the conservation of this flagship species, the project indirectly addresses the conservation needs of the entire ecosystem it inhabits. Moreover, the project emphasizes inclusivity by actively involving the broader community in environmental conservation efforts and promoting social responsibility. Through workshops and hands-on activities, participants are engaged in learning about the life cycle and ecological significance of the Apollo butterfly.

School Workshops in Austria:

As part of the LIFEApollo 2020 project, our Austrian partner, the European Wilderness Society, in collaboration with butterfly expert Otto Feldner, conducted  numerous engaging workshops in various Austrian schools, from kinder-gardens to high schools. These workshops were designed to capture the attention and curiosity of students and to create an interactive learning environment. 

Throughout these sessions, students were introduced to the captivating world of Apollo butterflies, delving into every stage of their life cycle, from eggs to fully developed adults. Vital topics such as habitat requirements, overwintering behaviors, and the significance of specific feeding plants essential for Apollo butterflies were covered in detail. Notably, these workshops ignited a sense of enthusiasm among students, who eagerly shared their knowledge about butterflies. This enthusiastic response underscores the importance of fostering a connection between young minds and the natural world.

Creation of Apollo Gardens:

The LIFEApollo2020 project also aims to build Apollo gardens, unique spaces dedicated to cultivating food plants essential for the caterpillars and butterflies of the Apollo species. In Austria, two such gardens were established, one involving secondary school students and the other engaging children from a kindergarten. These gardens not only served as educational tools but also as practical conservation measures. Students eagerly participated in their production, and during construction, the significance of plants that attract butterflies—especially the vital Sedum for the Apollo caterpillar—was highlighted. The success of the Apollo Gardens was evident through the satisfaction expressed by smiling students and teachers involved in the activity.

Nature Festival:

In Autumn, European Wilderness Society took an advantage of the chance to reach a wider audience by participating in the “Fest der Natur” event in Wels, Austria. EWS was one of more than thirty exhibitors that presented presented nature conservation initiatives. The engaging event featured interactive games and content designed to educate both younger and older about the importance and protection of the Parnassius apollo butterfly. By providing a platform for participants to actively learn and engage in nature conservation, the event highlighted the broader significance of protecting local nature and biodiversity. The positive response and varied program ensured that the project’s message resonated effectively.

2024: Mosel’s Apollo crowned as Butterfly of the Year!

Posted By: Vlado Vancura 565 Views 0 Comment ,

In 2024, the charming Mosel region has crowned the Apollo Butterfly as its Butterfly of the Year! This magnificent insect has captured the hearts of locals and visitors alike with its vibrant beauty and captivating charm. Choosing the apollo for Butterfly of the Year, a decision which was also influenced by nature conservation organisations such as BUND NRW, has a worrying background: In the Mosel region, pesticides are still used that send apollo population down a dark path.

The Mosel Region

The Mosel wine region in Germany is not only renowned for its picturesque landscapes and world-class wines but also for the unique ecosystem that thrives there. However, this delicate balance of nature is now under threat as the use of pesticides in the vineyards has begun to take a toll on the insects resident in the Mosel region, including the Parnassius apollo. The decrease of individuals in the Mosel region correlates with the use of pesticides in recent years. Pesticides are spread by helicopters and it is particularly noteworthy that at least the new substances used in recent times are applied without any nature conservation impact assessment.

The subpopulation of the Mosel region, namely Parnassius apollo ssp. vinningensis, only exists in this particular region. It differs slightly from apollo subspecies in the Alps, Sweden or from those found in Spain. Beyond its visual appeal, the Apollo Butterfly possesses an intriguing life cycle. The species is known for its preference for high-altitude habitats, making the Mosel region an ideal home if it were not for applied chemicals and pesticides.

Celebrating the Vibrant Beauty

The Apollo Butterfly’s recognition as Butterfly of the Year is a testament to its vibrant beauty and captivating charm. At the same time, however, it is a warning. Like in many other European regions as well as in Germany, the apollo population of the Mosel region is declining rapidly and is in great danger of extinction. Alternatives for harmful pesticides must be found if this beautiful butterfly should be protected. Moreover, it is essential to preserve the habitats that this species relies on. By protecting their preferred host plants and maintaining the natural balance of the ecosystem, the magnificent butterflies can thrive. In the Mosel region, visitors still flock to the area to witness the Apollo Butterfly in its natural habitat, with guided tours and educational programs providing an opportunity to learn more about this enchanting species. This might change in the future though if nothing is done right now.

The Apollo Butterfly’s striking appearance and graceful flight have also inspired artists and designers in the region. Their unique patterns and colors have been incorporated into various forms of art, from paintings to jewelry. Local festivals and events now celebrate the Apollo Butterfly, with dedicated butterfly-themed exhibitions and workshops. These festivities not only showcase the region’s rich cultural heritage but also raise awareness about the importance of preserving biodiversity and the delicate balance of nature.

As we celebrate the Apollo Butterfly being crowned as the Butterfly of the Year in 2024, we are reminded of the beauty and wonder that nature bestows upon us. We are also reminded of the harm humans can do to other creatures smaller and weaker than us if we do not realise that we are part of the natural ecosystem.

The beauty of butterfly wings

Posted By: Roman Manak 869 Views 0 Comment

Butterfly wings are the most striking part of a butterfly’s body and are certainly the reason why butterflies are so popular with people and why they are so attractive. The combination of all sorts of colours on butterfly wings is not just a random freak of nature, but it has several purposes.

One of these is recognition between individuals of the same species. At mating time, the male attracts the female by the colour combination on its wings. Last but not least, the colours on the wings serve as protection against predators. For example, some dull-coloured moths perch on tree bark during the day and, thanks to their inconspicuous colouring, blend in perfectly with the ground and escape the eyes of predators. Other butterflies have a warning colouration. Our hero Apollo will display its red-meshed hindwings in an attempt to scare off predators.

What causes the coloration of butterfly wings?

But what makes butterfly wings so colourful? It may sound surprising, but the colour is caused by thousands and thousands very tiny formations, a few tenths of a millimetre in size, which are shaped like scales. Even the scientific name of Lepidoptera butterflies is derived from these scales. In fact, the word Lepidoptera is a compound of the two Greek words lepís (scale) and pterós (wings) and was first used by the father of scientific nomenclature for plants and animals, Carl Linné.

Eye with scales on the hindwing of the Apollo

The scales are coloured with various pigments and this is one of the reasons for the colourfulness of butterfly wings. In addition, in some butterflies, the edges and various surface structures of the scales refract and reflect light and this causes them to shine.

The scales are stacked side by side on the butterfly’s wing and overlap each other; they are arranged like shingles on a roof. In some butterflies the number of scales per square millimetre can be more than 500, but in Apollo the number of scales is smaller, giving the wings a translucent appearance. If you ever catch a butterfly in your hand and get “coloured dust” on your hand, it is these scales that you have wiped off the butterfly’s wing.

What do butterflies need scales for?

The scales are therefore responsible for the colour and lustre of the butterfly’s wings. But they also have other functions. They are filled with air, which makes them very light and helps butterflies fly. They also serve as excellent thermal insulation. Scientists believe that this is the main reason why butterflies evolved scales. This is because they are not only on the butterfly’s wings, but also on the butterfly’s chest and other parts of the butterfly’s body, helping to maintain the high body temperature needed during flight.

Decline of Parnassius apollo

Posted By: Kamila Redererova 630 Views 0 Comment

Parnassius apollo, commonly known as the Apollo butterfly, is a beautiful and iconic species of butterfly found in Europe and Asia. Unfortunately, this species is on a rapid decline due to several factors, including habitat loss, climate change, and over-collecting.

The Apollo butterfly has a very specific habitat requirement, which is high altitude meadows and rocky slopes with specific plant species for feeding and breeding. However, these habitats are under threat from human activities such as tourism, agricultural expansion, and infrastructure development. As a result, the population of the Apollo butterfly is decreasing at an alarming rate. 

Factors of the decline 

Parnassius apollo belongs to the most attractive butterfly and very often appreciated not onlyby scientists but also visitors. Therefore, decline of this butterfly species is so sensitive and painful. Decline of Parnassius apollo, particularly in a central Europe is dated back already since the 19 centuries. 

Observations of gradual decline, some environmentalist even use the word extinction, of this butterfly in Europe identified numerous cases, proved that decline is very much due to combined negative impact on Parnassius population. 

There are several major factors contributing to the decline of the Parnassius apollo population. One of the main factors is habitat loss. The main reason for that are human activities such as tourism, infrastructure development, and agricultural expansion. 

Habitat requirements

The Apollo butterfly has very specific habitat requirements, including high altitude meadows and rocky slopes with certain plant species for feeding and breeding. When these habitats are destroyed or degraded, the butterfly population declines.

Habitat loss is one of the main factors to the decline of the Parnassius apollo
Combination of habitat loss, climate change, over-collecting, and pollution are the major factors contributing to the decline of the Parnassius apollo

Climate change

Climate change is another major factor affecting the Apollo butterfly population. The butterfly’s life cycle is closely tied to the timing of the availability of host plants and pollinators, which can be disrupted by changes in temperature and precipitation patterns. As a result, the butterfly may not be able to complete its life cycle and reproduce successfully.

Over-collecting 

Over-collecting of the Apollo butterfly is also a contributing factor to its decline. Some people collect the butterfly for commercial purposes or for private collections, while others collect it for scientific research. This can have a significant impact on the population, especially if it is not done sustainably.

Pesticide use

Finally, the Apollo butterfly is also affected by pesticide use and other pollutants in the environment. These substances can be toxic to the butterfly and its host plants, and can disrupt the delicate balance of the ecosystem.

Overall, a combination of habitat loss, climate change, over-collecting, and pollution are the major factors contributing to the decline of the Parnassius apollo population. It is important that effective conservation efforts are put in place to address these issues and protect this beautiful species.

Major groups of factors

Experts agreed on the three major groups of factors such as: 

a) natural factors including long-term climatic changes, habitat succession, and short-term weather anomalies; 

b) anthropogenic factors that include broad impact of industrialization and butterfly over-collecting; 

c) intrapopulation factors that include genetic erosion and behavioural changes. 

Habitat loss is undoubtedly the most destructive for Apollo’s long-term survival. There are several interesting researches and monitorings which provide very important information concerning causes of extinction of numerous butterflies in their biotopes in Europe. 

Conservation efforts

To help protect the Apollo butterfly, several conservation efforts have been implemented (one of them is our LIFE Apollo2020 project). These include habitat restoration, captive breeding, and protection of important sites. However, these efforts must be implemented on a larger scale and in a coordinated manner involving multiple stakeholders, including governments, NGOs, researchers, local communities, and individuals.

Conclusion

In conclusion, urgent action is needed to prevent the extinction of the Apollo butterfly. Conservation efforts must be comprehensive and well-coordinated to ensure the long-term survival of this beautiful and important specie

Very useful on this aspect is report developed by the expert of IUCN already two decades ago. These data provided important baseline for any kind of follow up researches and management measures to support survival rate of this rare butterfly. This work provides various protective measures that were, or should be undertaken to stop further Parnassius apollo decline. 

Climate change is a significant threat to the survival of Parnassius apollo. The altered environmental conditions and increased frequency of extreme weather events can negatively impact their habitats, food sources, and overall health and survival.

Parnassius apollo: The umbrella species guarding biodiversity

Posted By: Kamila Redererova 591 Views 0 Comment

When it comes to protecting our planet’s valuable biodiversity, it sometimes takes a hero to defend the masses. The Parnassius apollo is a champion in the fascinating world of butterflies. The Apollo butterfly, often referred to as a “umbrella species,” plays a critical role in protecting not only its own species but an entire environment rich with lesser-known species. In this article, we’ll focus on why the conservation of Parnassius apollo is so crucial and how it acts as a bioindicator, offering valuable insights into the health of its habitat.

The umbrella effect

Imagine a majestic forest, vibrant with life. Within it, an umbrella opens, shielding the delicate flora and fauna beneath from the harsh elements of habitat loss and environmental degradation. This metaphorical umbrella is the Parnassius apollo, a butterfly species that holds a vital position in the web of life.

When we say “umbrella species,” we mean that by looking after the Parnassius apollo, we actually keep many other animals and places safe too. We often talk a lot about saving big animals like tigers and pandas, but small creatures like the Apollo butterflies need our help too.

The domino effect of conservation

By focusing on the preservation of the Parnassius apollo and its habitat, we unintentionally protect countless other species living in the same ecosystem. This butterfly’s presence is indicative of a healthy and intact environment, with thriving populations of plants, insects, and other organisms that rely on the same resources.

The Parnassius apollo acts as an umbrella species, not only for the protection of biodiversity but also for the preservation of habitat mosaics. These mosaic-like habitats are composed of various interconnected ecosystems, creating a rich and diverse landscape. By conserving the species itself, we, in turn, protect other species and habitats associated with it.

Many butterfly species benefit from habitat conservation measures taken to protect the Apollo. A significant number of these butterflies find themselves listed in Red Books of Animals and other rare and endangered species lists, highlighting the critical importance of the Apollo’s preservation.

A sensitive bioindicator

Beyond its role as an umbrella species, the Parnassius apollo serves as a remarkable bioindicator. A bioindicator is a species whose status provides valuable information about the overall health of its ecosystem. In the case of Parnassius apollo, it proves to be particularly sensitive in this regard, making it an invaluable asset in environmental monitoring.

One of the specific areas where the Parnassius apollo excels as a bioindicator is in the monitoring of xerothermic biotopes—ecosystems characterized by hot, dry conditions. These habitats are under constant threat due to climate change and human activities. As an indicator species, the Parnassius apollo can tell us a great deal about the quality and health of these fragile environments. If the butterfly thrives, it suggests that the ecosystem is healthy and stable, while a decline in its population signals potential problems.

Protect Apollo, protect our planet

In a world where nature faces many challenges, the Parnassius apollo stands out as a true hero. It’s not just looking out for itself but also for a whole community of other creatures and the places they call home. And, it’s also a smart detective, helping us understand how our environment is doing. By taking care of the Apollo, we’re not just helping one species; we’re making sure that the amazing web of life on Earth remains strong and healthy. This butterfly helps us protect other animals and special places like sunny meadows and rocky grasslands. By doing this, we’re making the world a better and more diverse place for the future.

Apollo in Winter

Posted By: Krzysztof Kalemba 3092 Views 1 Comment , , , , , , , ,

In this article you will learn about the secrets of butterfly survival in winter conditions

Winter is a long period to which butterflies adapt in many different ways. Some of them overwinter as adults, while others undertake long migrations. Some, like Apollo spend the winter in eggs. By learning the characteristics of the Apollo butterfly cycle, you’ll realize that it doesn’t have an easy path to follow until warmer days arrive. If you want to understand our hero’s biology, learn about the longest period of his life, which is Winter. We’ll start with the prelude, which is the formation of eggs.

BEFORE EGGS ARE FORMED

The very short flight period of adult butterflies is the time devoted mainly to pairing and egg-laying. The eggs must be well constructed to provide a safty for the caterpillars in winter conditions. During copulation, the female is protected by a chitinous [1] material called sfragis.

After a few days, the female starts laying eggs, she is able to lay up to 300 of them. Such a number of eggs increases the chance for larvae to find a host plant [2], such as some species of Sedum, Sempervivum and Rhodiola.

LIFE FORMATION AND SURVIVAL

Winter and cold are harsh conditions for most butterflies. The time that the caterpillars spend in the eggs is the time that will determine their future population [3]. It is worth considering what happens to the eggs after the female lays them, what processes are responsible for such unusual changes in nature?

The eggs have a chitinous layer that protects future caterpillars from pathogens [4] and high moisture. They also include various amino acids, proteins and enzymes. The eggs themselves are very solid, but they allow air to flow inside, not all of them come out perfect and not from all of them will hatch caterpillars. There are still many factors to decide. Already in the fourth week after their laying, caterpillars appear in the eggs, but for the next eight months they will lie dormant. The whole cluster will wait until the spring comes during the winter cold.

TIME AND REACTION

While waiting for the time to emerge from the egg, the caterpillar experiences many trials.

The first of them is early spring – a time when temperatures can periodically increase enough to give a false signal to the little ones to wake up. Such a situation can happen even in autumn, when the heat and warm nights last for a long time, and even in winter if there is a sudden warming. It is enough that the temperature rises at night and the morning rays of the sun warm the eggs. For the caterpillars, such a change means death due to the returning cold and lack of food. The large number of eggs produced by each female increases the chances that some will hatch at the right moment. This is one of many adaptations to the conditions in which the butterfly lives.

In the end of Winter and start of Spring comes the proper period of awakening for caterpillars. Depending on the region, it can be slightly shifted in time, but usually it is between March and April. It may also happen that winter will shift and warming will come later. The nights are still chilly in the mountains, but time is pressing as the nutrient material inside the egg is running out. When the time comes, the caterpillars will begin to feed on the egg wall and will chew through its shell. They will then gain strength and take off quickly in search of a host plant.

Adult butterflies equipped with wings are not particularly fast, but their caterpillars are determined to move very quickly. If these little caterpillars don’t find food in time, they won’t survive. This is another adaptation that increases the chances of survival of the species.

A year in the life of a butterfly is trials, chances and races, a series of successes and failures. All this to close the cycle and make the next generation of species. Only in this way they can survive in a harsh and rapidly changing world.

[1]- chitin – a chemical compound (polysacharide) forming the upper skeleton in some organisms along with proteins, calcium and magnesium salts obtained with food in the case of insects.

[2]- host plant – a plant that the organism needs for development in most of its life cycle.

[3]- population – a group of individuals of one species inhabiting a given area at a certain time.

[4]-pathogens – biological agents that cause diseases in living organisms, including viruses, bacteria, protozoa and fungi.

SEDUM COLLECTIVE

Posted By: Krzysztof Kalemba 876 Views 0 Comment , , , , , , , , ,

Have you become familiar with the Apollo butterfly yet? It is also worth taking a moment to look at its host plants. We will focus on Sedum, a very interesting genus of plants from an even more interesting family. And as it happens in the family, nothing is so simple and obvious.

Author : Krzysztof Kalemba

Stonecrop (Sedum spp.) is a genus of the Crassulaceae plants, including more than 600 species according to various approaches, it is worth noting that this number is still not final, as research on this group is still in progress. Members of the Crassulaceae family can be found on all continents. Most of them are succulents, i.e. plants that have adapted to life in conditions of limited water availability by storing it in their tissues. Despite this, species of succulents can be found in a variety of habitats.

Among the Central European Sedum species, we find those of large size, often forming compact clumps of shoots, and smaller ones that like to dominate the space.We will focus on species from this region, as they are of particular interest to the Apollo butterfly (Parnassius apollo) in the area of our project activities.

Big Brother and cousins

Larger stonecrop species can be found both in lowlands and in higher mountainous locations. They share a similar structure of leaves and flowers, preferences for permeable soil (involving sand, rocks or stones) and southern exposure. Most of them are subspecies of Hylotelephium telephium which in its natural form has pink flowers. One of the most common subspecies is grand stonecrop (Hylotelephium maximum, Sedum maximum), which can be found in the mountains, forests, as well as in lowland areas, also in agricultural areas. You can recognize this stonecrop by its cream-colored flowers and bluish-green leaves. In Eastern Europe, flowers of a similar color are also found in Hylotelephium telephium ssp. ruprechtii, where we more often encounter a red-colored stem. Carpathian stonecrop (Hylotelephium telephium ssp. fabaria) is a species that prefers mountain and foothill areas rich in limestone, despite its similarity to the great sedum, it has light pink to maroon flowers. Depending on the location and soil, Hylotelephium stems may take on a reddish color.

Lesser on the family

The greatest diversity is found among the smaller species of the more numerous Sedum species. Differences between the color of leaves, flowers, shape, height and growth are more noticeable. As in the case of Hylotelephium, we have here species that prefer high mountains, foothills and lowlands. Some of them like areas heavily transformed by humans. The most common and recognizable species here is the gold moss stonecrop (Sedum acre). This one loves stone and sandy areas, it will not despise rubble or tracks. Its characteristic feature is the formation of turf, compact structure and numerous yellow flowers. A twin of the tasteless stonecrop (Sedum sexangulare), with shorter leaves, definitely freer areas richer in limestone. Jenny’s stonecrop (Petrosedum rupestre) is distinguished by longer and narrower leaves, higher raised flowers. The white stonecrop (Sedum album), widespread throughout Europe, will have a similar structure but white flowers.

Others feel good here to

As is often the case with plants, there are also species of foreign origin that are widespread in Central Europe. We have always had a passion for importing other species and experimenting. In this way, the two-row stonecrop (Phemidius spurius), with pink flowers and incised, spatulate leaves, began to escape to nature in the 19th century. Another escapee was an Asian species, the butterfly stonecrop (Hylotelephium spectabile) deceptively similar to the common species of Hylotelephium in Europe. An introduced species of foreign origin for Germany, Austria and Norway was the orange stonecrop (Phedimus kamtschaticus), similar to the two-row stonecrop but with yellow flowers.

Family abilities

Sedum plants are considered succulents for a reason, their ability to accumulate water in leaves, stems and tubers is remarkable. They are characterized by extraordinary vitality, the ability to reproduce in several ways and several defensive features. In fear of pests, a large part of stonecrops has developed a defense system. In defense against pests, a great number of stonecrops produce alkaloids, poisonous or unpalatable substances. Their function is to discourage insects from gnawing on the plants. The gold moss stonecrop contains toxic sedamine, sodimine and nicotine. The adult grand stonecrop is also able to increase its chances of survival thanks to sedamine and piperidine, a feature that butterflies have learned to avoid. Caterpillars of the chequered blue (Scolitantides orion) and the Apollo butterfly follow their rather strict diet, feeding mainly on stonecrops. The choice of such a group of host plants has meant that they must somehow cope with the presence of alkaloids. This forces them to constantly change their feeding sites and go after plants that have not yet produced enough alkaloids to harm the caterpillars.

This article is Part 2 of a series on the benefits of grazing for Apollo. You can read Part 1 here.

Forest and shrubs used to cover a much larger territory in Europe than they do today. Each part of Europe has its own history by which the forest was extensively logged and finally removed. In the case of the Carpathian mountains, this process began as early as the 14th century. It was a time when a growing density of human settlements in specific areas created pressure on the forest, with intensive logging that continued for centuries (Fred & Brommer, 2005).

This trend started to change in the last few decades, when large areas of forest were declared as protected areas. The tree line in particular became the subject of strict protection in many mountains in Europe. On top of that, large areas of the recently grazed land were abandoned, sheep were taken away and forest and shrubs spontaneously re-occupied the land. This process dramatically reduced the available habitat for Apollo, and still continues in some parts of Europe.

Active protection – grazing to stabilise the Apollo population

Like several other endangered species, the well-being of Apollo depends to a large extent on appropriate habitat and available food. Large areas which have been favourable for Apollo for several centuries are now more and more occupied by forest and shrubs. Maintaining the locality once inhabited by Apollo by removing trees and bushes have become important management activities.  

Removing the bush often creates appropriate conditions, particularly enlarging food-plant resources, for the larvae and butterflies. That activity can create fundamental conditions to support a stable Apollo population.There are arguments that maintaining the Apollo population means keeping and protecting the open landscape as much as possible. This is particularly important in the areas where fragments of the Apollo population have survived.

Grazing is a well-tested method to maintain open landscape and keep the pressure of trees and shrubs succession under the control. Well-managed grazing can significantly contribute to controlling the self-recovery of trees and shrubs and provide favourable habitat important for Apollo, as well as provide food, nutrition and other benefits to Apollo as well as livestock.

Carefully managed grazing is just one practical example of how to support the shrinking Apollo population. Long-term cooperation between nature conservationists and managers of grazing can even help to set up Apollo reintroduction projects and to try to breed completely new colonies of this butterfly. This activity can become an interesting example not only to implement sophisticated grazing methods but also to maintain and support the protection of Parnassius apollo.
