Tenthredinidae
Tenthredinidae is the largest family of sawflies, with well over 7,500 species worldwide, divided into 430 genera. Larvae are herbivores and typically 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. The family has no easily seen diagnostic features, though the combination of five to nine antennal flagellomeres plus a clear separation of the first abdomen, abdominal tergum from the metapleuron can reliably separate them. These sawflies are often black or brown, and 3 to 20 mm long. Like other sawflies, they lack the slender "wasp-waist", or Petiole (insect), petiole, between the thorax and abdomen, characteristic of many hymenopterans. The mesosoma and the metasoma are instead broadly joined. The Tenthredinidae are also often somewhat dorsoventrally flattened, wh ...

Allantinae
Allantinae is a subfamily of sawflies in the family Tenthredinidae, and the largest subfamily of that family, with about 110 genera. The subfamily is considered to consist of five to six tribes, and are medium to large sawflies. Economic importance Host plants include strawberries, raspberries, roses, violets, dogwood, and loosestrife. Larvae often pupate in fruit or wood. '' Monostegia abdominalis'' has larvae that feed on Primulaceae, and was introduced into Canada in about 1965 and is a major pest of Yellow Loosestrife ('' Lysimachia terrestris'').
