A Quadriocellar Hedychridium caeruleum (Hymenoptera: Chrysididae) from Manitoba, Canada

A specimen of Hedychridium caeruleum (Norton) with four ocelli was discovered in Manitoba, Canada. The supernumerary ocellus is located to the right of the ocellar triangle, which otherwise appears normal. This is the first report of an ocellar or ocular teratology within Chrysididae, adding to the small body of literature currently available on supernumerary ocelli within Hymenoptera. This is the first published record of H. caeruleum in Canada.
