On thermoregulation inVespula germanica(Fabr.) (Hymenoptera, Vespidae) and other Vespidae [PDF]

open access: yesBolletino di zoologia, 1982
Abstract The vespid hymenopteran, Vespula germanica (Fabr.) regulates its thoracic temperature to around 33° - 38° C in environmental temperatures between 15° and 35° C.
