The inchman (Myrmecia forficata) is a species of bull ant that is native to Australia. The ants are recorded in the south eastern part of the country, but are most often found in Tasmania. The inchman is the most venomous of the bulldog ants, ranging from about 15 to 25 mm (0.6 to 1.0 in) long, but less aggressive than the Jack jumper ant. These ants are purplish-brown, with a black abdomen. Their large size gave them their name, although most are slightly smaller than the traditional inch (25.4 mm). Their nests may be inconspicuously hidden under a rock or in a small hole.
