Genus of wasps
Metopius is a cosmopolitan genus of parasitoid ichneumon wasps in the subfamily Metopiinae. They lay eggs inside caterpillars of Lepidoptera that are found in leaf rolls, and the adult wasps later emerge from the pupa. They are black and yellow striped and reach over in length. Their coloring may be mimicking potter wasps. "Metopius" spp. make a buzzing noise when captured.
