Diprionidae (conifer sawflies)

This is a small family of sawflies feeding on conifers. Around 100 species have been described which are mainly found in temperate regions. The larvae live gregariously and several species are serious pests. They take a characteristic U-shaped posture when disturbed and grow to a length of up to 30 mm. When fully grown, the larvae drop to the ground for pupation.

The adults are relatively small (usually 5-10 mm long) and have characteristic antennae with a variable number of short segments (14-32). Males are smaller than females and have feathery antennae. The antennae of females have fewer segments and are serrated.

The following genera are currently entered under Diprionidae:
