Worrying Surge in Threatened Wild Bee Varieties In the European Continent

The total of wild bee varieties in Europe facing dying out has more than doubled over the past decade, while the total of threatened butterfly types has nearly doubled.

This dire scenario for essential pollinators was revealed by research studies for the red list of threatened species, which found that at least over 170 bee varieties out of nearly two thousand were at risk of extinction in European nations.

The number of butterfly species at risk of extinction in European nations has grown from 37 to sixty-five since the earlier research, carried out 14 years ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.

“Beyond their beauty and cultural significance, pollinating insects like bees and butterflies are lifelines for our well-being, our food systems and our economic systems – supporting the fruits, vegetables and seeds that feed us,” stated the IUCN director general. “The newest European red list evaluations reveal major obstacles, with risks mounting for butterfly types and crucial native bee varieties.”

The reasons of the swift recent drops are the continuing destruction or damage of habitats caused by agricultural intensification and land abandonment, wetland drainage, overgrazing by livestock, and the utilization of chemical fertilisers and pesticides including neonicotinoids. The breaking up of environments suitable for pollinators greatly increases the danger of disappearances in specific areas.

Global heating is also demonstrated to be a significant danger: 52% of all threatened butterfly species in European nations are threatened by the climate change crisis – approximately twice as many as a decade ago.

Up to nine out of ten of plants that flower in European nations require animal pollination, as stated by the lead coordinator of the wild bee assessment. “Unfortunately, wild bee colonies are in drastic decline and cannot readily be substituted by managed colonies,” he said. “If non-managed bees vanish, many wild plants might be in danger as well – of which meadows rich in flowers and attractive orchid varieties are just a couple of instances.”

Fifteen species of bumblebees, which play a crucial role in aiding the pollination of peas, beans, peanuts and clover, and fourteen varieties of cellophane bee species, known for aiding tree pollination such as willows along with red maples, are now categorized as at-risk. Simpanurgus phyllopodus, a mining bee type unique to the mainland and the single type of this genus in the European continent, is now assessed as critically at risk – the research category nearest to dying out in natural habitats.

Butterfly types that are solely present on mountain tops are especially at risk to global heating as they must ascend higher as their habitats become hotter but eventually exhaust available space. In the southern part of Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among more than 40% of species endemic to Europe (solely present in Europe) at risk of extinction.

In the Mediterranean, types such as the severely threatened Karpathos grayling are threatened by intense dry conditions and fires.

At the same time, in the Arctic Circle, climate change is causing the timberline to advance northwards by many meters each year, with scrub taking over marsh and tundra. Higher temperatures also mean Arctic deer can no longer cross the ice to graze Arctic meadows and prevent them from overgrowing. 8 butterfly varieties are at risk of extinction in this zone, including the fritillary of Freyja and the Arctic ringlet butterfly.

“The greatest environment for all these pollinators is grassland rich in flowers and that is disappearing very fast in European nations because of all these factors,” remarked one of the lead coordinators of the butterflies assessment. “The encouraging aspect is that so many people are aware now and there’s a lot more understanding. Under the EU’s nature restoration regulation, all member states have to halt the decline in pollinators by the year 2030, and they are going to have to initiate measures. There are land holders who are engaged. It is hoped they can get the encouragements that will support them on their way.”

According to Martin Warren, there is “readily achievable actions” in terms of steps for pollinating insects which will not lower agricultural output – and might boost it – such as growers establishing margins rich in flowers around their cultivated areas.

EU commissioner for environment, characterized the preservation condition of wild bees, butterflies and other pollinators as “severe”.

“Urgent and collective action is required to tackle this threat. Together with member countries, the EU Commission has implemented an Europe-wide observation system for pollinating insects based on the EU nature restoration law, which will aid in following our progress. Now, we need to focus on implementation and partnership with member states to protect our pollinating species,” she said.

The release of the assessments on bees and butterflies follows the initial European-wide study on hoverflies, an additional crucial group of pollinators. Issued in twenty-twenty-two, it revealed that 37% of all hoverfly varieties in the European continent were threatened with extinction.
