Chrysis angustula is a species of cuckoo wasps, insects in the family Chrysididae.

They can be easily found also on walls of wooden buildings, old wood's doors, poles, log piles and dead tree trunks.

[4] These relatively small cuckoo wasps are part of the difficult-to-determine Chrysis ignita complex, with more than ten similar species.

The abdomen is rather elongated and shows a characteristic metallic golden color, with reddish or green sheen.

Similarly to other cuckoo wasps, they are brood parasites, laying their eggs in the nest or cavities of their host species, feeding on their larvae and on the food supply allocated to them.
