BEHAVIOURAL THERMOREGULATION IN THE FREEZE-TOLERANT ARCTIC CATERPILLAR

(Lepidoptera: Lymantriidae) spent most (60 %) of their time orienting towards the sun (i.e. basking) and only 20 % feeding, primarily near midday. Larvae usually basked after feeding, then either fed again or moved to a new feeding site. Basking larvae reached their highest body temperatures (Tb) of...
