Summary

Pompilinae is a subfamily of the spider wasp family, Pompilidae, known for laying eggs on paralyzed spiders. They exhibit distinct morphological characteristics that differentiate them from related subfamilies.

Physical Characteristics

Pompilinae are distinguished by minute differences in head structure, leg morphology, and wing venation. They possess oval to slightly sinuate inner margins of the eyes, a short labrum, and unequal lengths of tibial spurs on middle and hind legs. The hind leg features wide, blade-like bristles on the fifth tasomere.

Identification Tips

Examine the forewing; the medial vein (M) should fall short of the margin and Cu2 should be bent at the base. Also, note the unequal lengths of tibial spurs and the presence of small spines or pits on femora.

Distribution

Pompilinae are found worldwide with more than 2000 species across over 60 genera.

Diet

They lay eggs on the paralyzed bodies of their prey, which are typically spiders.

Reproduction

Females paralyze spiders and lay their eggs on them to provide food for the larvae once they hatch.

Evolution

Tribal classification has changed significantly over time, with various authors proposing differing numbers of tribes and classifications.
