Sterictiphora geminata (Gmelin, 1790)

Sterictiphora geminata

One of two species in this genus present in Britain and Ireland. The abdomen is mostly black with a bronze sheen (in S. angelicae only the first two tergites are black) and thorax surface is dulled by microsculpture and puncturation.

Sterictiphora geminata larvae feed on roses. Other larvae of this genus feed from the edge of the leaf working inwards in a meandering zig-zag pattern similar to the Elm Zig-zag sawfly.
