Allantinae is a subfamily of sawflies in the family Tenthredinidae,[2] 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.

[3] Host plants include strawberries, raspberries, roses, violets, dogwood, and loosestrife.

Larvae often pupate in fruit or wood.

[3] 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).
