Giant burrowing cockroach

The  giant burrowing cockroach  ( Macropanesthia rhinoceros ) is also known as the  rhinoceros 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 live for up to 10 years. Unlike some other cockroaches, they do not have wings and are not considered pests. The 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 m (3 ft 3 in), [1]  where they make permanent homes. 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 shells 12 or 13 times before reaching full size. When a cockroach  moults, it will appear pure white except for the eyes. The species is  ovoviviparous.
