Myrmecia forficata is the inchman ant of southeastern Australia and Tasmania. It looks a lot like its relative Myrmecia pyriformis and has a reputation as one of the most venomous bull ants. Here is what we know about this species.

The inchman ant

Myrmecia forficata is known as the inchman ant. Its large size gave it this name, although most workers are a little smaller than the traditional inch of about 2.5 cm. Workers are around 15 to 25 mm long.

Appearance

The inchman ant is purplish brown with a black gaster. It closely resembles Myrmecia pyriformis, which is usually larger and darker. Read more about Myrmecia pyriformis.

Where does it live?

The species is native to southeastern Australia. It is most common in the Australian Alps above about 300 metres, but can also be found down to sea level around Melbourne and in Tasmania. Nests are often hidden under a rock or in a small hole.

Behaviour

Like other bull ants, the inchman ant lives in colonies but forages alone. It hunts and scavenges for food and is described as less aggressive than the jack jumper.
