Cuckoo Wasps - Family CHRYSIDIDAE

Order Hymenoptera

This page contains pictures and information about the Cuckoo Wasps that we found in the Brisbane area, Queensland, Australia.
There are many Cuckoo Wasp species and they look very similar. Usually they are metallic blue or green in colour and are coarsely sculptured. Most species are external parasites of other wasp larvae. Females lay eggs in nest of other wasps (Eumeninae of Vespidae and  Sphecidae) while the nest host collect food for larvae. Cuckoo Wasp larvae hatch and feed on the food or the host larvae.
The adult Cuckoo Wasp's back is well armored and with abdomen concave beneath. When disturbed, it curl up into a ball. This is a defense behavior against the attack by angry nest host.
Cuckoo Wasps are common in Brisbane suburban. They are usually seen flying slowly looking for wasp nest.
