Sawfly. High-speed photograph of a sawfly (sub- order Symphta) in flight. 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 and their main food is pollen, although some species are at least partly carnivorous.
