Myrmecia urens

Myrmecia urens is a species of ant in the genus "Myrmecia" (bulldog ants) found in Australia.
Behaviour and ecology.
While pollination by ants is somewhat rare, the orchid "Leporella fimbriata" is a myrmecophyte which can only be pollinated by the winged males of this species. Pollination of this orchid usually occurs between April and June during warm afternoons, and may take several days until the males all die due to their limited lifespan. The flower mimics "M. urens" queens, and so the males move from flower to flower in an attempt to copulate with it.
