Thyreus

Thyreus is an Old World genus of bees, one of many that are commonly known as cuckoo bees, or cloak-and-dagger bees, and are kleptoparasites of other species of bees, mostly in the genus Amegilla. They all have strongly contrasting patterns of coloration – three species from the Sydney region, Thyreus nitidulus, T. lugubris, and T. caeruleopunctatus are bright blue and black.
