Summary

Proctotrupoidea is a hymenopteran superfamily chiefly characterized by its parasitoid life history, with most families being small and often lacking diversity, except for Proctotrupidae which has over 400 described species. Over time, several families have been reclassified into other superfamilies, highlighting the evolving understanding of these insects' taxonomy and relations.

Physical Characteristics

Typically ranges from 3 to 10 mm in size, with Pelecinidae reaching up to 25-70 mm.

Identification Tips

A key to families can be found in specific taxonomic references focusing on the identification of North American families.

Habitat

Diverse habitats, often associated with environments where host insects are found, as they are parasitoids.

Distribution

Worldwide, with 8 families established, 5 recognized in North America.

Diet

Parasitoids primarily of various other insects.

Life Cycle

Details on the life cycle are variable and can differ by family; many are known to develop within or on their host.

Reproduction

Reproduction typically involves laying eggs inside or on the body of a host insect.

Predators

Specific predators are not widely documented, but as parasitoids, they play a unique role in their ecosystems.

Ecosystem Role

Functions primarily as parasitoids, impacting host insect populations and contributing to ecological balance.

Evolution

Derived from ancient lineages within the order Hymenoptera, the superfamily has seen multiple families moved to other classifications in recent years.
