Anteoninae Aphelopinae Apoaphelopinae Apodryininae Bocchinae Conganteoninae Dryininae Erwiniinae Gonatopodinae Plesiodryininae Transdryininae Dryinidae is a cosmopolitan family of solitary wasps.

Many species have a marked sexual dimorphism, where males are totally different from the females in the size and shape of the body.

Females may also have front legs modified with a pinching apparatus which they use to restrain the hosts for their larvae during oviposition.

The larva feeds on the internal structures of the host, and as it grows larger it begins to protrude from the body.

The host is eventually killed and the larva leaves the dead body and spins a cocoon.
