The responses of riparian species of Bembidiini were tested in temperature [T] gradients under different relative humidity [r-H] conditions: The species tend to select lower T as time proceeds when there is an inverse gradient in T and r-H. However, with an exposure time of 2 h, the majority of the species selects the same main T region under varying r-H conditions. There are great differences in the preferred T ranges of the species, and this correlates with their degree of heat tolerance [H-T] (mainly tested by 1 h exposure in dry air at fixed T) and the T conditions prevailing in their microhabitats. No correlation between T preference/H-T and geographical distribution of Bembidiini species can be found, but general links between T preference, life cycle and geographical distribution of Carabidae are postulated.
