Description and distribution

Meteorines are characterized by an open 1st subdiscal cell and a four-sided 2nd subdiscal cell of the forewings. They have a distinctive petiolate waist. They are found worldwide, in habitats where their hosts can be found.

Use in biological control

Many hosts of Meteorines are considered pests, especially of forests, making them good candidates for biocontrol projects. ''Meteorus pulchricornus'' has been imported to North America on multiple occasions to attempt to control the gypsy moth. ''M. vesicolor'' was introduced to the United States in the early 1900s for the control of the brown-tail moth. ''M. trachynotus'' was investigated for control of
