THE MAIN REGULARITIES OF BUTTERFLY PHENOLOGY (LEPIDOPTERA, RHOPALOCERA) IN THE NORTHERN TIEN-SHAN MOUNTAINS (THE KIRGHIZ RIDGE)

摘要

The dynamics of butterflies phenology of butterflies in the northern Tien-Shan (the Kirghiz Ridge) were studied. The phenological structure of the fauna in every altitudinal belt is described. In all the belts, except for the subnival one, the first flying Rhopalocera species were polyzonal. The number of seasonal assemblages of butterflies was maximal in the subalpine altitudinal belt and minimal, in the subnival one. When passing from one belt to another one, the number of seasonal assemblages increased or decreased, and the portion of species characteristic for the summer seasonal assemblages became higher. The richest by characteristic species were the summer assemblages; the poorest ones were the first and last seasonal assemblages.
