Bluebottle, aka Blue 'ant' wasp

Diamma bicolor


A type of flower wasp, Blue "ants", aka Bluebottles, have a distinctive metallic blue-green body, with red legs. The female ranges up to 25 mm (1 inch) in length, is wingless and ground-dwelling, and exclusively hunts mole crickets, whereas all other species of tiphiids attack beetle larvae. The male is winged and about half her size.


It is a native of south and southeast Australia, including the Australian states of Tasmania, New South Wales, Victoria and South Australia. This one was in our garden.


It is the sole member of the subfamily Diamminae, and is both morphologically and behaviorally unusual among members of the family Tiphiidae. This female was very aggressive and kept raising her abdomen to mock a stinging attack.

I think there must be a derth of crickets on my property. I watched a jurassic moment when a female wasp had caught and was dragging quite a large spider.

This one was in a hurry to get away, that's for sure, Argy. Thanks Martin. I think I've seen that striped and winged one about as well, so it's a good conjecture. I'll keep an eye out for it now. I've spotted this species of Native flower wasp a few times now, once mated to the male, and always in our veggie garden:
