Summary

Euphorinae is a diverse subfamily of parasitoid wasps with over 1,150 species, known for their unusual behavior of attacking adult hosts and involvement in biological control of pest insects.

Physical Characteristics

Small, usually dark colored wasps, typically less than 5 mm in size.

Identification Tips

Euphorinae can be identified by their solitary or rarely gregarious nature and their habit of attacking adult hosts, which is unusual among parasitoid wasps.

Habitat

Euphorinae are found in various habitats, adapting to regions where their host insects are present.

Distribution

Worldwide, with a notable presence in the New World, having 31 genera in that region and over 1,150 species in approximately 50 genera total.

Diet

Euphorinae are endoparasitoids that primarily feed on adult insects and nymphs of hemimetabolous insects.

Life Cycle

They have a koinobiont endoparasitoid lifestyle, meaning they develop within a living host.

Reproduction

Solitary or, in a few cases, gregarious, reproducing by parasitizing host insects.

Ecosystem Role

They play a role in controlling populations of pest insects, making them significant in biological pest control.

Economic Impact

Some species like Dinocampus coccinellae are considered pests themselves, although they are not abundant enough to significantly impact coccinellid populations.
