	abstract = {We explore the physiological constraints of body temperature as related to body mass and ambient temperature during flight in endothermic dung beetles showing a mass-related breakpoint where species show strong vs. weak endothermy. We found two different strategies in the dung beetles prior to flight; larger beetles (41.9 g) elevate and maintain their body temperature (Tb) at levels well above ambient temperature (Ta) whereas smaller beetles{\textquoteright} (o1.9 g) Tb tends to conform with Ta. Physiological constraints analysis revealed a constant maximum tolerated temperature (in flight) of 42 1C and a minimum temperature for flight of around 25 1C. These, with body mass, may play a role in thermal niche partitioning and geographical distribution patterns. },
