Omalus biaccinctus is a species of cuckoo wasps belonging to the family Chrysididae.[1]
Distribution and habitat
This species is present in most of Europe (Austria, Belarus , Belgium, Croatia, Czech Republic, Denmark , Estonia, Finland , France , Germany , Greece, Hungary, Italy, Luxembourg, Poland , Spain , Switzerland and The Netherlands), in the eastern Palearctic realm, and in the Near East.[2] These wasps occur in musk forests.
Description
Omalus biaccinctus can reach a body length of about 4 mm (0.16 in). In these small wasps head, pronotum and mesonotum are unpunctuated but vaguely rough. The face is green-blue and antennae are brown, with the first two segments green. The thorax is blue-indigo and very convex. The abdomen is shiny golden-red, subglobular and wider than the fore-body. Wings are quite smoky in the rear half. Legs are blue-green and tarsi reddish-brown, but the first section is green.[3][4][5]
Biology
These wasps are nesting parasites of solitary wasps Passaloecus species.[6] This species has also been reported laying eggs inside living aphids, later preyed by aphid-hunting crabronids. In such a way O. biaccinctus through the aphids can enter in the nest of the crabronid in order to lay its eggs.[7]
