The click beetle Cardiophorus ulcerosus is a small beetle generally living in leaf litter or dead bark. Like other beetles this species can play 'dead' when handled but run away after a while. However one feature which differs from other beetles but is characteristic of click beetles is the loud click sound they emit either when overturned or trying to escape. The click 'mechanism' can be found on the underside as a pointed slotted appendage between the head and thorax. This species may be distinguished from the related Cardiophorus argiolus by the fused black spots (or band) which are separate in the latter.
