Currant Stem Girdler
A slender black stem sawfly that attacks currant and gooseberry bushes. Females girdle the stem tips with their ovipositor, causing them to wilt.
Did You Know?
The female girdles the stem above the egg insertion point, causing the tip to wilt and die, which provides the larva with softened stem tissue to feed on.

A metallic dark parasitoid wasp that attacks the pupae of noctuid moths in the soil. It is found across Europe in grasslands and open habitats.
