Summary

Ceraphronidae is a small family of hymenopterans with a poorly understood diversity, characterized mainly by their parasitoid lifestyle, especially targeting various insect groups.

Physical Characteristics

Size ranges from 0.5mm to 3mm.

Identification Tips

Females have 9 or 10 segmented antennae, while males have 10 or 11 segmented antennae. The middle tibiae have one apical spur, and the large spur on the fore tibiae is not forked apically. The stigma is linear and may be absent.

Habitat

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

Distribution

Approximately 35 species are found in Canada, with around 360 described species and an estimated 1000 species worldwide.

Diet

Most Ceraphronidae are believed to be parasitoids, specifically of flies (Diptera), thrips (Thysanoptera), moths (Lepidoptera), and lacewings (Neuroptera). Some species act as hyperparasitoids of Braconidae in aphid populations.

Ecosystem Role

Ceraphronidae play a role in controlling pest populations through their parasitoid behavior.

Evolution

The family Ceraphronidae was erected by Alexander Henry Haliday in 1833, distinguishing it from the closely related Megaspilidae based on specific anatomical traits.

Misconceptions

Due to their small size and the fact that many species are undescribed, there may be a general misunderstanding or lack of awareness regarding their ecological importance and diversity.
