Jumping Jack ant nest

Myrmecia pilosula


This low profile mound of pelletised dirt caught my eye and on close inspection, I could see jumper any workers scurrying all over the mound which had several entry/exit holes. On the mound there was no vegetation but scattered black pellets that looked like mouse droppings. The ants were clearly jumping jack ants as they moved in short jumps and had distinct orange mandibles, legs and antennae.


Light open forest - part of a national park ( Churchill NP)


These ants are known to decorate their nests with seeds, soli, dirt,sticks and bodies of other invetebrates. That might explain the mouse droppings.
Some species of rove beetle are said to thrive in nest chambers of these ants where they raise their brood. Skinks are also seen living in these nests.
Family: Formicidae
