These wasps are often highly sculptured, with brilliantly colored metallic-like bodies. Cuckoo wasps lay their eggs in the nests of other hymenoptera, usually other solitary bees or wasps. Many are parasitic on bee or wasp larvae. I found this single specimen rummaging around on our patio. He seems to like our lemon tree because it brings other wasps.
Chrysidines are distinguished from the members of other subfamilies in that most can curl into a defensive ball, in a process known as conglobation. This ability is shared with pill bugs, pill millipedes (which are often mistaken for pill bugs), and armadillos.
