Strategies of thermoregulation and foraging in two vespid wasps,Dolichovespula maculata andVespula vulgaris

Abstract

D. maculata, the white-faced hornet, stabilized (regulated) thoracic temperature (T Th) over wide ranges of ambient temperature (T a), whileV. vulgaris, the common yellowjacket, regulatedT Th poorly. The hornets also maintained a higherT Th than the wasps, sometimes heating 38°C aboveT a. Attacking individuals of both species had higherT Th than those… (More)
