A study published in PNAS analyzed four million records of pollinating insects from 1921 to 2020, revealing a sustained decline of wild bees across Europe. Most species lost presence in their distribution areas, a trend also seen in about half of the hoverflies (syrphids). While no mass extinction is observed, researchers warn that population reductions pose risks to biodiversity, ecosystems, and the environment. These insects play a key role in pollination, essential for wild flora and many crops like fruits, vegetables, seeds, and nuts.
