The blue ant (Diamma bicolor), also known as the blue-ant or bluebottle, is a species of flower wasp in the family Thynnidae. It is the sole member of the genus Diamma and of the subfamily Diamminae. Despite its common name and wingless body, it is not an ant but rather a species of large, solitary, parasitic wasp.

Distribution

The blue ant is endemic to south and southeast Australia, including the states of Tasmania, New South Wales, Victoria, and South Australia.

Description and identification

Blue ants have a distinctive metallic blue-green body, with red legs. The female ranges up to {{convert|25|mm|in|0|abbr=on}} in length, and is wingless. The male is smaller, about {{convert|15|mm|in|frac=8|abbr=on}}, and has wings.{{citation needed|date=January 2024}}

Biology

Blue ants are ground-nesting. They are unusual among members of the family Thynnidae in exclusively hunting mole crickets as larval provisions, whereas all other species of thynnids attack beetle larvae. The cricket is paralysed with venom injected by the female's stinger and an egg is laid upon it so the wasp larva has a ready supply of food.

Adults feed on nectar and pollinate various native Australian flowers, such as Lomatia silaifolia.{{cite journal| last=Hawkeswood | first=Trevor J |journal = Calodema| title= Record of pollination of Lomatia silaifolia (Sm.)

They are fast-moving and burrow under leaves to escape danger. They do not show aggression unless provoked.{{citation needed|date=January 2024}}
