The count of native bee types in European nations confronting dying out has more than doubled in the last ten years, whereas the count of at-risk butterfly types has close to doubled.
This critical situation for essential pollinating species was disclosed by scientific assessments for the IUCN red list, which established that at least one hundred seventy-two bee types out of over 1900 were facing extinction in the European continent.
The total of butterfly types at risk of extinction in the European continent has grown from 37 to sixty-five since the last study, performed over a decade past. A single species, the large white of Madeira (Pieris wollastoni) has now been classified as extinct.
“Beyond their visual charm and cultural importance, pollinating insects like bees and butterfly species are essential supports for our physical condition, our food systems and our economic systems – supporting the fruits, veggies and seeds that nourish us,” commented Grethel Aguilar. “The latest European red list assessments reveal significant difficulties, with risks increasing for butterflies and essential native bee types.”
The causes of the swift recent drops are the persistent harm or degradation of habitats caused by agricultural intensification and abandoned land, draining of wetlands, excessive grazing by animals, and the use of chemical fertilisers and pesticides including neonicotinoids. The division of environments suitable for pollinators significantly raises the danger of extinctions at local level.
Climate change is also revealed to be a primary risk: Fifty-two percent of all at-risk butterfly types in Europe are imperilled by the climate change crisis – approximately double the number as a decade ago.
Nearly 90% of plants that flower in European nations require pollination by animals, according to the wild bee assessment’s lead coordinator. “Sadly, wild bee groups are in drastic decline and are not easily replaceable by domesticated hives,” he said. “If native bees die out, many wild plants might be threatened too – of which bloom-filled grasslands and lovely orchid types are just a few examples.”
Fifteen types of bumblebees, which play a crucial role in pollinating crops such as peas, beans, peanuts and clover, and 14 types of cellophane bees, known for fertilizing trees such as willows along with red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee found only in the continent and the only species of this biological genus in the European continent, is now assessed as critically at risk – the scientific category closest to extinction in the wild.
Butterflies that are only found on mountain tops are particularly vulnerable to global warming as they have to climb upward as their living spaces become more heated but eventually run out of space. In Spain’s southern region, the Nevada grayling and the Andalusian anomalous blue butterfly are among over forty percent of European endemics (exclusive to Europe) facing extinction.
In the Mediterranean area, varieties such as the critically endangered Karpathos grayling butterfly are threatened by severe wildfires and drought.
In the meantime, in the Arctic Circle, climate change is resulting in the tree line to move north by tens of metres each year, with scrub invading marsh and tundra. Warmer conditions also mean Arctic deer can no more cross the ice sheets to feed on northern grasslands and keep them open. 8 butterfly varieties are facing extinction in this zone, including the fritillary of Freyja and the ringlet of the Arctic.
“The largest environment for all these pollinators is bloom-filled grassy areas and that is declining quickly throughout European nations because of all these factors,” said Martin Warren. “The encouraging aspect is that so many people are aware now and there’s a lot more awareness. Under the EU’s nature restoration regulation, all member states have to turn around the decline in pollinating species by the year 2030, and they are going to have to start doing something. There are property owners who are involved. We hope they can obtain the motivations that will help them on their way.”
As stated by Martin Warren, there is “easy opportunities” in terms of action for pollinating insects which will not lower food production – and may enhance it – such as growers creating margins rich in flowers around their fields.
the EU’s environment commissioner, characterized the conservation status of native bees, butterflies and additional pollinators as “severe”.
“Prompt and unified steps is needed to confront this risk. In collaboration with member countries, the Commission of the European Union has established an Europe-wide tracking system for pollinating species based on the EU nature restoration regulation, which will aid in following our advancement. Now, we need to concentrate on application and partnership with participating nations to safeguard our pollinating insects,” she said.
The release of the evaluations of bees along with butterflies comes after the first European-wide study on hoverflies, a further crucial pollinating insect category. Released in 2022, it revealed that 37% of all hoverfly types in Europe were threatened with extinction.
