Worrying Rise in Threatened Non-Managed Bee Types Throughout the European Continent

The number of wild bee varieties in the European continent facing extinction has more than doubled in the last ten years, while the number of at-risk butterfly types has close to doubled.

This dire scenario for vital pollinators was unveiled by research studies for the red list of threatened species, which found that at least over 170 bee species out of over 1900 were facing extinction in European nations.

The count of butterfly types facing extinction in the European continent has grown from 37 to over sixty since the last study, conducted over a decade past. One species, the Madeiran large white (Pieris wollastoni) has now been classified as extinct.

In addition to their beauty and cultural significance, pollinating insects like bees and butterflies are lifelines for our physical condition, our food systems and our economic systems – supporting the fruits, vegetables and seeds that nourish us,” commented Grethel Aguilar. “The newest European red list evaluations reveal serious challenges, with risks growing for butterflies and crucial native bee species.”

The reasons of the quick recent decreases are the persistent destruction or damage of living environments caused by agricultural intensification and land abandonment, wetland drainage, overgrazing by livestock, and the utilization of fertilisers and pesticides including neonicotinoids. The fragmentation of pollinator-friendly habitat greatly increases the danger of disappearances in specific areas.

Global heating is also demonstrated to be a major threat: Over half of all threatened butterfly types in Europe are threatened by the climate crisis – roughly double the number as a decade ago.

Nearly 90% of blooming plants in Europe require insect pollination, according to the lead coordinator of the wild bee assessment. “Regrettably, native bee populations are in severe drop and cannot be easily replaced by domesticated hives,” he said. “If wild bees die out, many native plants might be threatened too – of which bloom-filled grasslands and attractive orchid varieties are just a couple of instances.”

15 varieties of bumblebee species, which play a crucial role in aiding the pollination of crops such as peas, beans, peanuts and clover, and 14 types of cellophane bee types, recognized for pollinating trees such as willows and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee species found only in the European continent and the only species of this genus group in European nations, is now assessed as critically endangered – the scientific classification closest to extinction in the wild.

Butterflies that are only found on mountain peaks are particularly vulnerable to global heating as they have to climb upward as their environments become more heated but eventually exhaust available space. In southern Spain, the grayling of Nevada and the Andalusian anomalous blue are among above 40 percent of species endemic to Europe (solely present in Europe) at risk of extinction.

In the Mediterranean, varieties such as the critically endangered Karpathos grayling are imperilled by severe wildfires and drought.

In the meantime, in the Arctic region, global heating is leading to the forest boundary to advance northwards by many meters each year, with scrub invading bog and tundra. Hotter climates also mean caribou can not anymore cross the frozen water to graze northern grasslands and maintain them clear. 8 butterfly varieties are at risk of extinction in this zone, including Freyja’s fritillary and the Arctic ringlet butterfly.

“The largest environment for all these pollinators is bloom-filled grassy areas and that is declining quickly across Europe because of all these reasons,” remarked Martin Warren. “The good news is that so many citizens are aware now and there’s a lot more awareness. Under the European Union nature restoration law, all member states have to reverse the decline in pollinating species by the year 2030, and they are going to have to start doing something. There are land holders who are engaged. Let’s hope they can receive the encouragements that will assist them on their way.”

As per Martin Warren, there is “easy opportunities” in terms of steps for pollinating species which won’t reduce agricultural output – and might boost it – such as growers establishing flower-rich margins around their cultivated areas.

the EU’s environment commissioner, portrayed the conservation status of wild bees, butterflies and other pollinators as “critical”.

“Prompt and unified steps is required to confront this risk. Together with member countries, the Commission of the European Union has put in place an Europe-wide monitoring system for pollinating insects based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to focus on implementation and cooperation with participating nations to preserve our pollinating species,” she said.

The publication of the evaluations of bees along with butterflies comes after the first Europe-wide assessment of hoverflies, another crucial pollinating insect category. Released in 2022, it disclosed that 37% of all hoverfly species in European nations were threatened with extinction.
