  • 1. Measurements of body temperature (Tb) in the field demonstrate that Platypedia putnami var. lutea Davis regulates Tb through behavioral mechanisms. 2. Thermal responses (minimum flight temperature 17.3°C, maximum voluntary tolerance-temperature 32.5°C, and heat torpor temperature 44.4°C) of P. putnami var. lutea are related to the altitude of their habitat. 3. Water loss rates increase with ambient temperature (Ta). Water loss rates are not significantly different at the extremes of the active Tb range but increase significantly when exposed to elevated Ta. 4. Acoustic activity was restricted at 6.7°C Tb range. This is similar to the lower end of the Tb range for singing measured in cicada species that produce sound with a timbal mechanism. 5. The use of the wing musculature to produce acoustic signals in P. putnami var. lutea does not increase the Tb range over which the species can call compared to timbal calls produced by other cicada species. © 2002 Elsevier Science Ltd.
