Habitat

Associated with the nests of mud dauber , particularly in sheltered situations such as beneath overhangs, in cavities, or on human structures where construct mud . The has been observed in both natural and anthropogenic environments.

Distribution

Originally African; now through introduction. Documented from North America (including the conterminous 48 United States), Hawaii, French Polynesia, and other regions. The has been transported via international commerce, with females building nests inside shipping containers.

Diet

are known to feed on nectar. Larvae are parasitic, consuming the paralyzed spiders provisioned by mud daubers for their own offspring.

Host Associations

Sceliphron caementarium - Primary ; black and yellow mud dauber

Life Cycle

Females infiltrate active mud dauber nests and lay inside . The larva consumes the prey items (paralyzed spiders) intended for the host offspring. Developmental details specific to this are not documented in available sources.

Behavior

Females wait near nests and enter when the host departs to hunt. When detected by hosts, individuals roll into a tight ball; the dense, pitted is impervious to host bites and stings. This defensive is characteristic of the Chrysididae.

Invasion History

Chrysis angolensis represents a well-documented case of a parasitic wasp establishing globally through unintentional human transport. The was first described from Angola in 1881 and has since been recorded across multiple continents, with its spread linked to the global distribution of its Sceliphron caementarium.
