The once-abundant Alexanor butterflies, with their bright yellow, black, red, and blue wings, are vanishing from southwestern Albania's flowery slopes. These delicate creatures, like many other butterfly species, face a grim fate due to human impacts, including climate change.
Researchers have identified 58 of Albania's 207 butterfly species as being at risk, sounding an urgent alarm for conservation efforts.
A Sensitive Barometer of Ecosystem Health
Anila Paparisto, an entomologist at Tirana University, emphasizes that butterflies act as "nature's mirror." Their presence or absence reflects the conditions of the ecosystems they inhabit.
In the picturesque district of Zvernec, Paparisto leads a team of researchers and students working tirelessly to identify the remaining butterfly species and document those that have already gone extinct.
Their findings reveal a complex interplay of factors affecting butterfly populations.
Climate Change and Temperature Extremes:
The early arrival of spring and excessively high temperatures in January and February disrupted the delicate balance for butterfly larvae.
While warmer weather encouraged egg hatching and larval growth, the subsequent cold temperatures in April proved fatal for their survival.
These temperature fluctuations are directly linked to climate change, affecting the timing of key life stages for butterflies.
Urbanization and Habitat Loss
Albania's coastal areas, including Zvernec, have witnessed rapid urbanization, encroaching resorts, and apartment blocks.
These developments, combined with overfishing and climate change, have also impacted migratory bird populations. While some butterfly species decline, others thrive-often to the detriment of the environment.
For instance, the invasion of a non-native moth, introduced through ornamental plants from China, has devastated over 80% of Albania's boxwood forests since 2019.
Pesticides and Agricultural Practices
The use of pesticides in agriculture poses a significant threat to butterfly populations. These chemicals not only directly harm butterflies but also affect their food sources-native plants and flowers.
Sustainable agricultural practices that minimize pesticide use are crucial for preserving butterfly habitats.
Urgent Call for Conservation
The decline of butterflies has far-reaching consequences. Beyond their intrinsic beauty, these insects play a crucial role in pollination and serve as a vital link in the food chain.
As butterfly populations dwindle, the entire ecosystem faces disruption. The phenomenon is akin to the famous "butterfly effect," where small changes can have significant ripple effects across nature.
In the face of these challenges, scientists, policymakers, and communities must unite to protect Albania's butterflies and preserve the delicate balance of its ecosystems.
The fate of these winged wonders serves as a stark reminder of our collective responsibility to safeguard biodiversity and combat climate change.

What other species are affected by climate change in Albania?
Apart from the declining butterfly populations, climate change has also impacted other species in Albania. Here are some notable examples:
Migratory Birds
Several species of migrating geese, including the Greylag Goose, the White-fronted Goose, and the rare Lesser White-fronted Goose, have largely failed to make their winter pilgrimage to Albania's marshes in recent years. These disruptions in migratory patterns can have cascading effects on ecosystems.
Boxwood Forests
The arrival of a non-native moth, introduced through ornamental plants from China, has ravaged more than 80% of Albania's boxwood forests since 2019. This invasion highlights the vulnerability of native ecosystems to climate-related disturbances.
Other Insects and Wildlife
While specific data may vary, climate change affects various insect species, amphibians, reptiles, and mammals. Shifts in temperature, precipitation patterns, and habitat availability impact their survival, distribution, and behavior.
Albania's rich biodiversity faces significant challenges due to these climate-related shifts. Conservation efforts and awareness are crucial to mitigate further damage and protect the delicate balance of its ecosystems.
