Tenthredinidae

Tenthredinidae is the largest family of sawflies, with well over 7500 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. As with all hymenopterans, common sawflies undergo complete metamorphosis.
