Facing the Heat: Thermoregulation and Behaviour of Lowland Species of a Cold-Dwelling Butterfly Genus, Erebia
Table 1
Summary of measured values for the two lowland butterfly species Erebia aethiops and E. medusa and for low- and high-altitude populations of E. euryale are shown; data for the remaining alpine congeners are available in [14]. N(F, M) = the number of individuals measured (females, males); Ta = air temperature; Tm = microhabitat temperature; Tb = body temperature.
