Central Germany Insect Populations Show Early Recovery Amid Asian Hornet Threat

Researchers observing insects in central Germany report a noticeable increase in activity among several species, including night butterflies and the once‑endangered Segelfalter. While the observations suggest a partial rebound, scientists caution that robust data confirming a reversal of the long‑term decline are still lacking and that comprehensive studies will take years.

At the same time, the invasive Asian hornet (Vespa velutina) continues to spread across German states. The EU has classified it as an invasive species, and German nature‑conservation authorities advise the public not to attempt nest removal themselves due to safety risks. The hornet preys on native insects, threatens pollinators, and can cause crop losses by feeding on fruit, adding further pressure on Germany's ecosystems.

Both developments highlight the fragile balance of German biodiversity, with signs of recovery for some native insects countered by the growing impact of an invasive predator.
