Altitude of habit at and its seasonal change in three Pieris butterflies, P. rapae, P. melete and P. napi were investigated. The results might suggest the possible existence of two distinct ecologic subsets, a lowland type and a montane type, especially in melete. In addition, interspecific competition for habitat could exist between the three species.
