Common Name:   Common Sawflies

Description:  The common sawflies are “broad-waisted” wasps whose larvae feed on the foliage of trees and shrubs.  Females are equipped with a saw-toothed ovipositor that allows them to cut slits into the bark of twigs where their eggs are laid (hence the name “sawfly”).  Adults usually have filiform antennae with 7-10 segments.   Larvae resemble lepidopteran caterpillars but have more than five pairs of abdominal prolegs.
