The Metopiinae are a worldwide subfamily of the parasitic wasp family Ichneumonidae.

In most genera the upper portion of the face forms a triangular process that extends between the antennae.

Larger species may mimic aculeate wasps in coloration and by producing buzzing noises when captured.

The wasp's stout legs and smooth face may be used to help females push their way into the leaf roll so they may reach the host with their short ovipositor.

Adult females may bite hosts in order to feed on their hemolymph.
