| Description: Many grasshoppers also bask in the sun, elevating their body temperature to 40°C or even higher. R. I. Carruthers and his colleagues (1992) described how some species of grasshoppers even adjust their capacity for radiative heating, Hr, by varying the intensity of their pigmentation during development. When reared at low temperatures, these species appear to compensate by developing dark pigmentation; while at higher developmental temperatures, they produce less pigmentation.
