Description
European wheat stem sawfly. View of two European wheat stem sawflies (Cephus pygmaeus) feeding on the nectar of a buttercup (Ranunculus sp.). This particular sawfly is a pest which attacks wheat, rye and barley. The sawfly's name comes from its saw-shaped ovipositor (not seen here). The females use the ovipositor to cut slits in stems and leaves, and then lay their eggs in the slits. Sawflies are usually active during the daytime. Their main food is pollen, although some species are at least partly carnivorous.
