: Omalus aeneus.

Omalus aeneus is a relatively common species that may be found in shrubs and warm slopes with large amounts of dead wood. Based on DNA-barcoding, O. aeneus seems to consist of five separate species in Fennoscandia. The species-complex therefore needs to be revised. Probably the species have different preferences among the hosts given for Omalus aeneus, which are Crabronidae in the genera Passaloecus, Pemphredon, and Psenulus.
