We came across quite a few of these beetles in the Namib-Naukluft park at Sossusvlei.
Becuase it lives in a desert, it drinks by using its own bumpy back surface, which causes accumulation of water droplets. To drink it stands on a small ridge of sand. Facing into the breeze, with its body angled at forty-five degrees, the beetle catches fog droplets on its hardened wings and back. The droplets accumulate and coalesce until their combined weight casues them to roll down the beetle's back to its mouth.
