Summary

Pemphredonini, commonly known as Aphid Wasps, consists of solitary wasps known for their unique nesting habits and prey preferences, primarily provisioning their nests with aphids and thrips.

Physical Characteristics

The primary morphological distinction between Pemphredonidae and Psenidae is that Pemphredonidae never have more than two submarginal cells in their forewing, while Psenidae have three submarginal cells.

Identification Tips

Look for wasps with two submarginal cells in the forewings for identification as Pemphredonidae.

Habitat

Solitary wasps that dig tunnels in the ground or plant material for nesting.

Distribution

Global distribution, with approximately 700 species across ~30 genera.

Diet

Larvae are carnivorous, feeding on paralyzed aphids or thrips provisioned by the female.

Life Cycle

Females hunt for prey, paralyze them, and provision the nest with these prey items for the larvae to feed upon after hatching.

Reproduction

Females lay eggs on paralyzed prey items in the nest cells they create.

Ecosystem Role

They play a role in controlling aphid and thrips populations by preying on them and provisioning them for their larvae.

Collecting Methods

• Netting adults directly
• Searching for nests in the ground or on plants

Preservation Methods

• Ethanol preservation for specimens
• Pinning adults for display

Evolution

Pemphredonidae is sister to Philanthidae and previously part of a larger classification that has since been revised, elevating some groups to family status.
