Acroricnus
Acroricnus is a genus of ichneumonid wasps that parasitize mud-dauber wasps (family Sphecidae). At least one species, A. seductor, has been studied for its host detection behavior and acts as a kleptoparasitoid, consuming spider prey and young host larvae in mud-dauber nests. The genus includes eight described species distributed across multiple continents.
