Life cycle of Carabus granulatus Linnaeus 1758 (Coleoptera, Carabidae) in Western Transbaikalia

Abstract

In conditions of Western Transbaikalia, Carabus granulatus Linnaeus 1758 has a one-year spring–early summer life cycle with the hibernation of the last age larvae. The most optimal habitat conditions and the life cycle realisation for the species were found on the floodplain meadow, which was pronounced in the optimum sex and age-related structure with identification of stages of development of adult beetles and larvae in comparison with the steppe and saline meadows. Warm and long autumn of 2018 in Western Transbaikalia was conducive to the lengthening of the seasonal activity of species and the life cycle realisation characteristic of the conditions of the Russian Far East and Japan.
