Gold Cuckoo Wasp

A brilliant green and gold metallic cuckoo wasp found across southern Europe. It parasitizes the nests of potter wasps and mud daubers.

💡

Did You Know?

Its metallic coloration is produced by nanoscale structures in the cuticle rather than pigments, similar to how opals create color.

Cuckoo Bee

A slender, wasp-like bee with yellow and black banding that lacks pollen-collecting structures. It is a brood parasite that sneaks into the nests of mining bees to lay its eggs.

💡

Did You Know?

Like cuckoo birds, these bees lay their eggs in the nests of other bee species, where the cuckoo larva kills the host egg and consumes all the stored food.
