Summary

Megaspilidae is a small family of hymenopterans with a significant number of undescribed species, primarily functioning as parasitoids. The family consists of 13 genera and is essential in the ecosystem's control of pest species.

Physical Characteristics

Distinguished by a very large stigma in the wing, relatively constricted metasomal petiole, and three grooves in the mesoscutum.

Identification Tips

Look for the wing structure and unique body shape compared to closely related families, particularly the large stigma and petiole features.

Habitat

Many species are found in the soil, with some being wingless.

Distribution

Approximately 52 species are found in North America, with around 35 species reported in Canada. Globally, there are about 450 described species and an estimated 1000 species.

Diet

Most Megaspilidae are believed to be parasitoids, primarily targeting sternorrhynchan Hemiptera. A few species may act as hyperparasitoids.

Ecosystem Role

As parasitoids, they play a role in controlling populations of other insects, particularly Hemiptera.
