Endothermy during terrestrial activity in large beetles

CA Bartholomew and TM Casey

The large tropical American beetles Strategus aloeus (Scarabaeidae) and Stenodontes molarium (Cerambycidae) can endogenously maintain metathoracic temperatures 5 degrees to 7 degrees C or more above ambient temperature for many hours. During such periods, their activity is exclusively terrestrial and their oxygen consumption equals that of active mammals of the same size. Before and during flight they elevate metathoracic temperatures by an additional 8 degrees to 10 degrees C.
