We investigated the thermoregulatory behavior, thermal responses (minimum f
light, maximum voluntary tolerance and heat torpor temperatures) and the ef
fect of body temperature (T-b) on call parameters in the cicada Diceroproct
a olympusa (Walker). Regression of T-b as a function of ambient (T-a) or pe
rch temperatures (T-p) suggests thermoregulation is occurring. Thermoregula
tion occurs through behavioral changes that alter the uptake of solar radia
tion. T-p is a better predictor of T-b than is T-a. Thermal responses (mini
mum flight temperature 20.4 degrees C, maximum voluntary tolerance temperat
ure 37 degrees C, and heat torpor temperature 46.7 degrees C) may be relate
d to the humid, grassland habitat of the species. in contrast to other acou
stic insects, no significant relationship was found between the temporal pa
rameters of the calling song and T-b within the population of D. olympusa.
