Blue ant

The blue ant (Diamma bicolor, also known as the faceblue-ant or bluebottle) is, despite its name and its appearance, not an ant at all, but rather a species of large solitary parasitic wasp sometimes known as a flower wasp. It is a native of south and southeast Australia, including the Australian states of Tasmania, New South Wales, Victoria and South Australia. It is the sole member of the subfamily Diamminae, and is both morphologically and behaviorally unusual among members of the family Tiphiidae.
