Flightless black beetles, such as this one, are often encountered nosing along the hiking trails, searching for dead and decaying vegetable material to eat. The hardened front wings are fused together so flight wings never develop. When these beetles feel threatened they raise their abdomens into the air and point them at the source of the threat. Under duress, they can emit a foul-smelling fluid. The common names given can be applied to a number of species here in the Park.
