Rhinotia haemoptera

This is a very distinctive Belid weevil due to its strong colouration.  It is part of the Lycid Beetle batesian mimicry ring.  The Lycid beetle has noxious chemical defense and hence predators are unlikely to attempt to eat insects with this colour pattern.  This weevil has been investigated and it has no chemical defenses of its own (Moore and Brown, 1989).  Rhinotia haemoptera is distributed from SE Queensland, down to Tasmania and across to South Australia in dry sclerophyll forests and woodlands.   Hawkeswood et al. (1994) commented that the beetle is uncommon to rare throughout its range, but we have found a significant number in a small area at the Tasmanian Bushland Garden.
Adults feed on the leaves and branchlets of predominantly Acacia species.
