Sawflies

Description:

The Tenthredinidae is the largest family of sawflies, with well over 6000 species worldwide. Larvae are typically herbivores and feed on the foliage of trees and shrubs, with occasional exceptions that are leaf miners, stem borers, or gall makers. The larvae of externally feeding species resemble small caterpillars. They go through complete metamorphosis. Athalia are smallish, 5-8 mm in length. Antennae have 10-13 segments.
