Sawflies
a group of insects belonging to the order Hymenoptera and distinguished by the peculiar conformation of the ovipositor of the females, which is composed of two broad plates, with serrated or toothed edges, by means of which they incise the stems and leaves of plants, and deposit their eggs in the slits thus formed. The turnip fly, Athalia centifoliæ, and the gooseberry fly, Nematus grossulariæ, are examples.
