Tasmania’s endangered Simpsons Stag Beetle (Hoplogonus simsoni) is a flightless, glossy blue-black beetle found only in a small area of north-eastern Tasmania. This ground-dwelling beetle reaches up to 32 mm in total length.
It has enlarged mandibles (jaws) which, in their resemblance to the antlers of a male deer (or stag), give these beetles their name. The jaws are mainly decorative though, as this beetle does not hunt as it does not eat!!  - all their necessary bodyfat is accumulated in the pupae/larval stage while it is developing underground: and this is also why it has such 
 miniscule eyes  It lives in leaf litter on the floor of mature wet eucalypt forest, damp forest, rainforest and mixed forest. A deep layer of accumulated leaf litter is vital to the survival of this species.
