Megaphragma
Quick Summary
The genus Megaphragma belongs to the family Trichogrammatidae, which are tiny, parasitic chalcid wasps. Members of the genus Megaphragma are among the smallest known insects, with some species measuring less than 0.2 mm in length.1
These wasps are parasitoids, meaning their larvae feed and develop within the eggs of other arthropods. The female wasp lays her eggs inside a host egg. When the wasp larvae hatch, they consume the host embryo before pupating and emerging as adults. In some species, males complete their entire life cycle within the host egg, mating with their sisters before dying.1
