Stilbum cyanurum, the large cuckoo wasp, is a species of cuckoo wasps (insects in the family Chrysididae).[1][2]


Stilbum cyanurum can reach a length of about 20 millimetres (0.79 in).[3] The colour range of this widespread species is considerable.[4] Head and thorax usually are bluish green, while the abdomen is golden red.[5]


These wasps parasitize various mud-nesting hymenoptera belonging to the Eumenidae family (Eumenes unguiculatus, Eumenes unguiculatum, Katamenes arbustorum), Sphecidae family (Pelopoeus distillatorius, Sceliphron caementarium, Sceliphron destillatorium and Sceliphron madraspatanum) and Megachilidae family (Chalicodoma, Megachile).


This widespread species is present in Spain, Switzerland, Afro-Tropical Region, Australian Region, East Paleoarctic ecozone, Near East, North Africa and Oriental Region.[5][6]
