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

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 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.

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.

Partner Meeting in Austria

In June, the LIFE Apollo2020 project team gathered for a partner meeting, this time in Austria. The main goal of this event was visiting the habitats of the Apollo butterfly. In Austria, there are still some habitat sites where Parnassius apollo butterflies fly and its populations exist. 

Two entire days were spent for visiting the intact habitats, during which a few imagines were spotted. A lepidopterist (an expert specializes in studying butterflies) was present to guide the team around the sites. This meeting turned out to be very important since breeders from various countries came together to share their expertise.

Austria’s Apollo habitats provided an excellent example for the entire project team. For the success of the LIFE Apollo2020 project, it was very important to visit the sites bacause this allows a better and crucial understanding of functionality of existing habitats in other countries. Therefore, by observing where the Parnassius apollo likes to live, the selection of reintroduction sites will be much easier. 

The sites visited around Austria differ greatly and exhibit unique characteristics. Some are close to settlements, others close to train tracks and yet others are located on high mountains and steep rocks. The differences between the habitats are striking and incredibly interesting because they show that the Apollo is very well adaptable to many different environments as long as there is sun, stonecrops (Sedum sp.) for the caterpillars and nectarous plants for imagines. The project team was pleased to conduct this fruitful and interesting meeting while monitoring methods were discussed and exchanged between breeders and scientists. Acquired experience and knowledge will be used to improve the project.

Here are some photos of the various habitats and the magnificent Parnassius apollo itself.

Field activities carried out by all partners until March 2023

Monitoring actions

KPN & KP: Monitoring studies in 2022 covered 33 observation sites selected on three areas:

  • in the vicinity of Jelenia Góra, for the recognition of habitats in the vicinity of the place of reintroduction of Apollo’s butterfly on Chojnik sub-site,
  • in the vicinity of Uniemyśl Complex sub-site, for the identification of habitats in the vicinity of the Field Station of the Klub Przyrodników,
  • the Kaczawskie Mountains, due to the presence of closed quarries and other habitats that may be potential reintroduction sites for Apollo butterflies.

ČSOP: Monitoring of host plant Hylotelephium maximum in the CZ side of the Sudetes took place during the past year as well as monitoring of habitats in our subsite. In the near future, we need to focus on these activities which are also linked to the Citizen science campaign.

VIS: We have conducted habitat monitoring on a portion of the project sites to determine how many nectariferous and host plants are present on our project sites and to know how many host/nectariferous plants need to be seeded. While moving in the field during monitoring, we also collected seeds at appropriate times for later sowing.

EWS: Training of dogs has been completed and the first dog is certified. The first monitoring of caterpillars is planned in April 2023 in Milders, Karteis, Lofer and Virgen.

Active Conservation

KPN: We carried out sheep grazing on an area of 9,8 ha of meadows around Chonik Mt. to improve the condition of habitats. We organized an International Shepherd Dog Competition in Karkonosze. This event is a tourist attraction and a great opportunity to promote grazing as a method of nature protection, maintenance of traditional professions (i.e. shepherd) and protection of species, including butterflies closely related to habitats like xerothermic grasslands and Molinia meadows that are dependent on this traditional form of management. We have new permissions to include to our actions new meadows near Chojnik Mt. (5ha) and we plan shrubs removal from meadows in autumn 2023.

KP: We haven’t started any active conservation actions yet. They are planned for 2023. We have obtained the necessary consents to carry out the activities from the plot owners and we are in the procedure aimed at leasing key habitats for the species within the Uniemyśl sub-site. However, we have begun the process of making arrangements for conducting active conservation activities in the Kruczy Kamień reserve. 

ČSOP: Extensive debushing and deforestation on nearly 1 ha of the subsite has been done and has thus contributed to the restoration of the valuable forest-free habitat necessary for the successful reintroduction of Apollo. Monitoring of habitats has been done in the subsite as well as identification of the first stepping stones nearby. Support of the host plant population by seeding and sowing also took place; however, it is necessary to continue these activities, especially immediately after the opening of the vegetation stand.

VIS: Three sites were mowed by hand (or with the help of small machinery) and two of them were grazed by sheep. Three of the subsites were seeded with our main food plant Hylotelephium maximum at the end of 2022 and in January and February of 2023. 

EWS: The first restoration was undertaken in Lofer and Fieberbrunn in 2022 in June and September. The next habitat restoration is planned after the flight period starting in September 2023 in Milders, Hinterbichl, Virgen and Leisach. Sedum and feeding plants will be planted in May/June 2023 depending on weather in Murtal, Fieberbrunn, Lofer, and the new area Fließ, Tyrol. 

Our breeding farms and how they changed

KPN: The Karkonosze National Park obtained 60,518 eggs of Apollo for wintering 2021/2022 from our own breeding farm. After transferring part of the material for breeding at the Field Station of the Klub Przyrodników in Uniemyśl (209 eggs) and the breeding farm in Barchov (366 eggs), 59,943 eggs were allocated for breeding. 36,921 caterpillars hatched from them, which is 61.5% of the initial breeding material in 2022. The Karkonosze National Park has allocated 21,562 caterpillars for reintroduction, thus leaving 15,359 individuals for further breeding. In the KPN breeding farm, 1095 imago (7%) were obtained from 15,359 caterpillars, including 810 males and 285 females. We designated 51 males for reintroduction. 

KP: We started breeding in a temporary portable tent. From the breeding farm in KPN we received 209 eggs, from which we eventually obtained 40 butterflies. We obtained 2866 eggs from our own breeding, which are intended for further breeding in 2023. The blueprint of the target breeding tent was made and a contractor was selected and began work on its construction. We obtained plant seedlings in the field. We have started establishing a base of nectariferous plants (host plants for imago) in the garden of the field station in Uniemyśl, as well as farming of Sedum maximum (host plant for caterpillars) in the Forestry Nursery of the Kamienna Góra Forest District in Krzeszów.

ČSOP: The breeding facility and process was established within an already existing breeding farm of the most endangered Czech butterfly species in a private facility led by Miloš Andres.  

It differs from the breeding farm in KPN primarily by its size, the Czech one has a much smaller capacity – last year about 366 eggs from PL were brought in at the beginning of April and about 200 imagos have hatched.

In this breeding farm, up to thousands of individuals of different developmental stages of the Czech species of butterflies are bred; Apollo is bred in hundreds. This is the 1st ever legal breeding of Apollo in the Czech Republic. The infrastructure of the breeding facility resembles a classic 3m x 2,8m foil greenhouse, but it is covered with a scaffolding net – it protects against some external influences while remaining airy, the rainfall shade is provided by a plastic foil. The big difference is also that in the Czech breeding facility the mating is controlled – the breeder selects individuals individually for the breeding “in hand”.

VIS: The breeding station of our organization is in the construction phase. The greenhouse itself is already standing, but minor landscaping is still needed in its immediate surroundings. Also, the production of the netted part of the greenhouse and its equipment have to be arranged, which are tasks for the next month. However, we have already sown Hylotelephium maximum in the greenhouse and will shortly be sowing nectariferous plants for adult butterflies in the vicinity of the greenhouse (so far we have seeds of Centaurea jaccea agg. and Centaurea scabiosa).EWS: Specialist has been actively breeding 200 caterpillars. He is breeding the subspecies Glocknerius, Bartholomeus, Noricanus, Loferensis and Karteisjuvavus for the release. The improvements of the breeding farm will begin after the current breeding.

Other Infrastructure works

KPN: We have purchased the following equipment necessary for conservation activities:

  • a logistic support for KPN in the form of a 4×4 off-road vehicle,
  • drone for the preparation of documentation of natural habitats,
  • watering system garden in Centrum Informacyjne Karpacz,
  • wood milling machine to clearing/shrubs removal from meadows.

KP: We have obtained design documentation for the Apollo Ecocenter heating system in Uniemyśl, as well as a design for landscaping around the area station. We have also obtained a design for a breeding tent and its construction has begun. Some of the landscaping work has also begun.

VIS: Before the construction of our breeding station, we have secured the fencing of the land, which will be used not only for the breeding of Apollo butterflies but also for the cultivation of host plants and other purposes.

Since the breeding farm is located behind the village, we provided increased security not only by fencing but also by using two photo traps on poles with sending data to a mobile phone and email.

An important birthday and why you should #followapollo

30 years of bringing green ideas to LIFE is the motto of the birthday of the LIFE program, which also co-finances our LIFE Apollo2020 project. In these thirty years, the program has co-funded no less than 5.500 projects . Thirty successful years in which LIFE has helped over 1.800 wild animal and plant species, including of course our Parnassius apollo. The entire LIFE Apollo2020 team is very proud to be part of the LIFE family since last year.

So today LIFE turns 30 and we wish you all the best for your birthday! Here’s to at least 30 more years of success, giving us all hope and inspiration for the future.

To celebrate this great day, we invite you to support our project, just as LIFE does:

Become a part of the LIFE family and #followapollo

In the coming weeks, months and yes, even years, we will not only share with you information about Parnassius apollo, its habitats and its relevance to our ecosystem but also show you how you can get active yourself and do your part to protect this beautiful butterfly and many more insects.

#followapollo means being active

Follow apollo means not only passively following but also being active! You only need your smartphone or tablet, open eyes and an attentive look and you are part of it. If you spot an Apollo butterfly, take a picture and upload it on iNaturalist in our project LIFE Citizen Science for Parnassius apollo.

And the best thing is, you can do it while hiking: The Apollo butterfly is a typical mountain species that prefers the meadows and pastures of the mountains of continental Europe. It usually occurs at altitudes from 400 to 2300 m above sea level. So put on your hiking boots and off you go!

Do you want to know more about Parnassius apollo, how to recognize it, which plants it needs or how big it grows? Then stay with us and #followapollo
