Description: It is an insect belonging to the family Chrysididae, commonly known as a cuckoo wasp, distinguished by its small to medium size, compact body, and striking metallic coloration, dominated by emerald green, blue, and golden reflections. The exoskeleton shows fine sculpturing with dense punctation, producing a strong iridescent sheen. The abdomen is partially retractable, a typical defensive adaptation that allows the insect to shield its most vulnerable segments when threatened.

Geographic distribution: It is mainly distributed across sub-Saharan Africa, with confirmed records in Angola and neighboring regions of southern and central Africa. Its occurrence is closely linked to warm climates that support both suitable hosts and floral resources.

Habitat: It inhabits open and semi-open environments, including savannas, shrublands, forest edges, and dry vegetation areas. It is often found where exposed soils, dead wood, or natural cavities are present, as these conditions favor the nesting sites of its host species.

Feeding: Adults primarily feed on nectar and sugary secretions, visiting a wide variety of flowering plants. This diet provides essential energy for flight and reproduction. Larvae are parasitic, developing at the expense of other insects, most commonly solitary hymenopterans.

Behavior: The species shows active and agile behavior, performing short and rapid flights. It is solitary and does not form colonies. Females display a discreet and cautious strategy when locating host nests, entering briefly to lay eggs without being detected.

Reproduction: Reproduction is cleptoparasitic, as females lay their eggs inside the nests of other hymenopterans. The larvae of Chrysis angolensis consume either the stored food or the host itself, completing their development within the foreign nest. This strategy minimizes parental investment and is a defining trait of the group.

Conservation status: It has not been specifically evaluated on a global scale. However, populations are considered locally stable, though potentially affected by habitat loss, pesticide use, and declines in host insect populations.
