Rhinoceros Roach (Macropanesthia rhinoceros)

The Rhinoceros Roach (Macropanesthia rhinoceros) is also known as, Rhino Roach, Giant Burrowing Cockroach and Litter Bug (the latter name may be misleading, as cockroaches are not true bugs). They are native to Australia and mostly found in tropical parts of Queensland. They are the world's heaviest species of cockroach (although Blaberus giganteus is the longest) and can weigh up to 35 g (1.2 oz) and measure up to 80 mm (3.1 in) in length. They can also live up to 10 years!

Unlike some other cockroaches, they do not have wings and are not considered pests. This particular species of cockroach plays a vital part in the ecosystem by consuming dead leaves, eucalyptus in particular, and recycling other matter. True to their name, they may burrow down in soil to a depth of about 1 metre (3 ft 3 in) where they make a permanent home. Males and females can be differentiated by the "scoop" on the head; the male has the scoop and the female does not. They grow by shedding their outer shell 12 or 13 times before the cockroach reaches full size. When a cockroach moults it will appear pure white except for the eyes. This species is ovoviviparous and will give birth to live young (nymphs).
