Commonly known as “Pie-dish Beetles” Helea is a genus of darkling beetles (Tenebrionidae) that are widely distributed across Australia, occurring everywhere except for high rainfall areas in the south, east, and north. Adult Helea spp. are nocturnal and will forage on the ground for decaying vegetation and fresh animal dung. The unusual flanges that give the pie-dish beetles their common name are primarily used to protect their undersides from attacks by predators. It is also thought that their flattened body form is an evolutionary adaptation to living under loose bark of Eucalyptus.
