"Some nocturnal dung beetles have been shown to increase their ball-making and ball-rolling velocity when their thoracic temperature increases. In these beetles, dung is a precious commodity that allows them to find a mate and feed their larvae. Discovering the resource soon is important so that they can start rolling a ball as soon as possible and take it to a distant place for burying. The beetles first detect the dung by olfactory cues and fly towards it rapidly. As they firs… " - How do poikilotherms thermoregulate
