Blue Cuckoo Wasp

A uniformly deep blue metallic cuckoo wasp found across Europe and Asia. It parasitizes various cavity-nesting wasps and bees in dead wood and walls.

💡

Did You Know?

Its entirely blue coloration without any red or gold makes it one of the most distinctive cuckoo wasps in Europe.

Winter Moth

A cold-hardy moth whose tiny green inchworm caterpillars defoliate fruit and shade trees in early spring. Females are virtually wingless and crawl up tree trunks to lay eggs.

💡

Did You Know?

Sticky bands wrapped around tree trunks in autumn can trap the wingless females and prevent egg-laying.
