These insects hail from subtropical and tropical parts of Queensland, Australia. These hefty bugs are third in length behind the madagascar hissing cockroach (#2) and the Megaloblatta longipennis (#1). Due to their numbers, these roaches are listed as Least Concern by the IUCN.

3.) Their diet consists almost solely on dried eucalyptus leaves. So they are a helpful consumer that help clean fallen leaves from the ground.
4.) In captivity, they will also eat fruits and vegetables.
5.) Females have a shovel-shaped head that aids in digging burrows.
