The rescue mission for Apollo continues in Czechia

Last year, our Czech partner ČSOP Hradec Králové managed to light up (not only) over a hectare of densely overgrown rocky terrain for Parnassius apollo, which was covered with impenetrable trees and thickets up to 15 metres high. But our efforts did not end there! Thanks to long-term support from the Škoda Auto Foundation and a partnership with the KRNAP administration, this winter we have managed to open an area that is now two to three times larger than some of the sites where Apollo still survives in Slovakia or Poland.

The work is really extreme and dangerous, and in some places you literally have to do magic on a rope. Through the Krakonoš Gardens project, we have been able to purchase special equipment that allows us to safely reach even the most inaccessible places.

And that’s not all. So far we’ve only focused on one main location, but in the coming period we’ll start preparing a second home for the Butterfly King, which is nearby. We have also walked the surrounding area in detail, mapping the occurrence of both feeding and nectar plants, as well as the surrounding meadows and potential corridors that can serve as a network of stepping stones for the Apollo. These are the kind of microhabitats that help the butterfly king to cross the road when travelling to a new home or mate. It’s a bit like imagining the stones you use to hop from one side of a river to the other.

We’re looking forward to getting the place all smelling and buzzing. Last year, the restored rocky areas have already attracted various species of flowering plants and insects, which had not had enough space and light here before, including, for example, Hornet moth tied to the Spurges or Zygaena ephialtes, which was known on the Czech and Polish side of the Krkonoše Mountains from only one location, although it used to be common here in the past. And thanks to the new finds of rare butterflies last year, it is now indisputable that the activities aimed at the return of Parnassius apollo are helping several of the rarest butterfly species in the Krkonoše Mountains, such as the least and forest Small blue or the Silver-spotted skipper, to survive.

Apollo, as this massive mountain butterfly is also called after the god Apollo, is facing great difficulties today. Its numbers are declining rapidly across central Europe due to deteriorating conditions in its natural habitat, which are affected by both human activity and climate change. Even in the aforementioned sites in Poland and Slovakia, it is no longer thriving, mainly due to the abandonment of traditional farming practices, where excess and sprawling plants were regulated primarily by grazing animals. Last year, Parnassius apollo numbers declined by somewhere up to 90%. This project could thus play a key role in conserving the Central European gene pool of this iconic species and maintaining the population of this butterfly in our region.

The caterpillars of the next generation of Apollo hatched from eggs in the rescue kennel a few weeks ago, and now there are hundreds of them. The actual hatching of the butterflies could take place in June, after which we plan the first experimental release of males at the Krkonoše sites where the field work mentioned last year took place. It does not make much sense to reshape the habitat according to the so-called “human view”, even if we are convinced that our efforts are correct. By observing certain behavioural traits of butterflies, which they can demonstrate directly in the field, we can learn from unnecessary mistakes and guide our efforts in the right direction.

Summary of Apollo EduActivities in Austria 2023

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.

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.

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.

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.

Livestock Grazing’s Role in Preserving Apollo’s Habitat

By Vlado Vancura

Domestic grazers, like livestock, might seem to be an unexpected ally for Apollo butterflies. Their role in creating a suitable habitat for this butterfly is fascinating. When the livestock graze, they systematically remove the emerging sprouts of trees and shrubs. That is their way how maintaining an open landscape. It is a process that helps to diversify meadows and preserves the open landscape that P. apollo thrive.

In the past, the role of creating suitable habitats, not only for Apollo butterflies but also for various other insects, was primarily fulfilled by native grazers like red deer, roe deer, wild goats, wild horses, European bison, or also the extinct auroch. These wild herbivores played a crucial part in shaping the landscape through their feeding behavior, preventing excessive growth of shrubs and trees. The unintentional impact of these grazers resulted in the removal of growing shrubs and young trees, maintaining open spaces. These open spaces allowed sunlight to reach the ground, establishing and sustaining the specific conditions vital for the life of Parnasius apollo. Simultaneously, this natural process diversified plant life, offering a variety of nectar sources for butterflies and host plants for their larvae.

Today, domestic animals such as cows, sheep, goats, and horses play a comparable function in habitat preservation to native grazers. The grazing actions of these domestic grazers help to create open spaces and allow sunlight to reach the ground. As a result, domestic grazers actively encourage the growth of a wide range of plant species that serve as nectar supplies for adult butterflies (imagines) and host plants for larvae. With careful management, domestic grazers can become collaborative partners in biodiversity conservation. This example vividly demonstrates how human actions, when coordinated with natural rhythms, can considerably benefit the well-being of P. apollo butteflies.

Grazing behaviours varies among domestic grazers. Sheep carefully nibble close to the ground, resulting in properly groomed areas.  As browsers, goats extend their reach to shrub leaves and twigs, causing vegetation to change structure. Cattle use a sweeping grazing motion to impact bigger areas.  Each species makes a distinctive contribution to the shaping of environment. Understanding and applying the various grazing habits of numerous domestic grazers allows us to build a balance that closely matches natural processes and in which also Apollo butterflies can thrive.

Today, the thriving habitat of the Parnassius Apollo, encompassing alpine and subalpine grasslands, dry calcareous grasslands, and slopes in upland areas, faces a threat from uncontrolled vegetation overgrowth. The delicate balance crucial for supporting the unique flora essential to the butterfly’s life cycle depends on well-maintained open spaces. Ensuring stable Apollo populations necessitates a habitat that provides both food plants for the larvae and nectareous plants for the adults. Domestic pastures provide as a safeguard, preventing spontaneous overgrowth, which happens quickly when grazing is reduced or stopped. Strategic grazing management, particularly with the help of goats, proves effective in reducing the vegetation growth and protecting a vital environment for the Parnassius apollo.

This demonstrates how coordinated conservation efforts, particularly through effective domestic animal grazing management, can be realised. When faced with the difficulty of protecting important open spaces, incorporating grazing practices emerges as a viable solution to ensure Parnassius apollo’s existence. It provides a compelling model for harmonious interaction with the environment while preserving the captivating world of these butterflies.

Happy Winter Holidays!

As snow covers the landscape, marking the end of the Apollo butterfly season, our project team wrapped up the outdoor activities with a final round of debushing in various regions. As we transitioned from the field to the office, we were immersed in the task of analysing and summing up monitoring data from our breeding farms and habitat monitoring.

Reflecting on the previous year, our international team is proud of not only the successful breeding and habitat preservation efforts, but also the impactful educational activities held to promote awareness about the Parnassius apollo. During the peak seasons of Apollo butterfly activity, spring and summer, we organised a number of engaging events in Poland, Czechia, and Austria, such as the creation of Apollo gardens, school classes, workshops, or open days. These activities were intended to emphasise the importance of protecting nature and our mountain Apollo.

And what actually happens to Apollo during the winter? This butterfly employ a unique survival strategy. As adults, Apollos do not migrate or overwinter, preferring the warmth of the sun. Before dying in late summer or early autumn, Apollo butterflies place their eggs near caterpillar food plants. There, the eggs patiently endure the cold and even snow, waiting for warmer days to arrive and begin their incredible transformation from a small egg to a magnificent butterfly.

As we conclude this year, we extend warm holiday wishes to all, with gratitude for your support in our efforts to conserve these creatures. May the festive season bring you joy, peace, and the warmth of cherished moments. See you in 2024!

How dogs assist in the detection of Apollo caterpillars

People discovered the sensitivity of a dog’s nose thousands of years ago, initially using it for hunting. Fast forward to present, and these animals have evolved into valuable members of our society, serving in police, customs, military, and rescue missions. Dogs have an incredible sense of smell that is a million times more sensitive than ours. It is related to the numerous scent receptors in their noses and the highly developed nasal processing centers in their brains. Dogs not only use their noses to detect scents, but they can also differentiate between various odours with amazing accuracy. 

Thanks to that, dogs have become indispensable in research and conservation projects over the last 30 years. These sniffer dogs have been trained for a variety of tasks ranging from tracking wolves, lynx, wildcats, or bats to identifying carcasses (dead bodies), litter, and even targeting small insects. The possibilities are almost limitless, as long as the target object emits a smell, dogs can track it down. While this type of use of dog is common in the USA, Canada, Australia, and New Zealand, the use of nature or species protection dogs remains relatively unknown in Europe. 

And #LIFEApollo2020 is proud to be one of these scientific projects!

What: Our focus is on collecting data about Parnassius apollo with detection dogs playing a key role in mapping caterpillar population across selected sites. These dogs ensure precise and non-invasive data collection by identifying unique odors associated with Apollo caterpillars and their habitats.

How: Dogs undergo a special training, that teaches them to recognize the unique odors associated with Apollo caterpillars. At first, the dog sniffs the live caterpillars and gets a treat for it. Then, tea bags scented with the caterpillar odor are introduced as a game element. The dog learns to associate finding the tea bags with getting a reward. As the training progresses, the dog practices in different places to get better at identifying the caterpillar scent. This simple but effective method helps the dog find the Apollo butterfly caterpillar in the wild.

When: Fieldwork usually takes place from March/April to June, when the caterpillars hatch from the eggs and crawl around. 

Why: Dogs with their great sense of smell easily overtake humans in finding and detecting targets. The caterpillar monitoring, facilitated by the human-dog team guides us in conservation efforts, allowing us to make informed decisions on preserving this endangered species in its natural habitat.

October 2023 was a month of conferences!

In October, LIFE Apollo2020 was presented at two significant conferences!

The congress took place in Heraklion, Crete, from the 16th to the 20th of October. This international event was an important meeting for more than 1000 entomologists and enthusiasts from the European Union, as well as representatives from overseas (UK, USA, Australia). The diversity of attendees transformed ECE 2023 into a global gathering, enabling a rich exchange of ideas and experiences.

The congress offered a truly comprehensive program, involving thematic sessions such as invasion biology and climate change, ecology and behavior, biodiversity and conservation, and much more. Workshops, poster presentations, excursions and hundreds of lectures provided the participants with the unique opportunity to learn about the latest research and developments in the field.

Our team member Tomáš E. Vondřejc held a scientific poster presentation on “Conservation of Parnassius apollo in Poland, Czech Republic and Austria under the theme of “Biodiversity and Conservation“. The project LIFE Apollo2020 made a great impression, capturing the attention of dozens of individuals with a keen interest in the conservation of P. apollo butterflies. Particularly captivating were the specifics of Apollos’ breeding farms and their operation. The innovative approach of using dogs for butterfly identification sparked broad interest as well, opening possibilities for the application of this measure in various conservation projects.

Throughout the congress, Tomáš had the opportunity to engage in conversations with numerous experts in the field, notably those involved in other LIFE projects with similar focuses, such as SouthLIFE and LIFE for Pollinators. The Project LIFEApollo2020 also caught an attention of the CINEA representatives from the European Commission, leading to a detailed discussion about the project. The outcome was successful, with LIFE Apollo2020 being pointed out as an exemplary case of good practice in their presentation, positioning it as one of the most outstanding species-focused projects for implementation.

The Apollo Project team is very grateful to be a part of ECE2023 and looks forward to future opportunities.

The LIFEApollo2020 team from Poland and Czechia participated from 19th to 20th October in the scientific conference ‘Apollo butterfly – research, protection, and monitoring’ in Červený Kláštor, Slovakia. Thanks to the event organized by Pieninský národný park (PIENAP) and Pieniński Park Narodowy (PPN), we had the opportunity to present our project to a broader international community of scientists and practitioners.

Our team delivered three presentations in total. Tomasz Suchan from Instytut Botaniki im. W. Szafera Polskiej Akademii Nauk w Krakowie discussed ‘Genetic research of the Apollo butterfly as part of the LIFE Apollo2020 project’, David Číp, representing Skupina JARO shared insights on ‘Experience in the protection and breeding of the Apollo butterfly within the JARO Group‘, and lastly, Dariusz Kuś from Karkonoski Park Narodowy addressed ‘Active protection of the Apollo butterfly in Karkonoski National Park – the LIFE Apollo2020 project’.

The conference offered an excellent platform for engaging in discussions, exchanging experiences, and gaining knowledge about conservation initiatives in various regions of Europe and the world. Our collaboration with PIENAP and PPN holds significant importance, as we share common objectives, enabling us to mutually enhance our projects and effectively protect Parnassius apollo and its natural habitats.

We also appreciate the dedicated moderators, Mr. Paweł Adamski and Mr. Ludomir Panigaj, for facilitating productive communication among participants.

Decline of Parnassius apollo

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. 

LIFE Apollo2020 is present at the XII European Congress of Entomology 2023!

Parnassius apollo: The umbrella species guarding biodiversity

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.
