This grasshopper relies on camouflage to avoid predators, rarely attempting escape.

[1] Atractomorpha similis (as with other members of its genus) is depauperate in heterochromatin, though the total amount of that DNA varies between populations.

[3] Males from Australia carry between one and ten extra copies of chromosome A9, with one being the most common in natural populations.

The species has been recorded in New South Wales,[1] Fraser Island, Western Australia, and northern Queensland.

[3] It is the most common of three members of its genus found in Australia, the others being A. australis (which favours cooler environments) and A. hypoestes (which is limited to the Arnhem Land escarpment).
