ABSTRACT. The life cycle of Pterostichus planipennis R.F. Sahlberg, 1844 in the conditions of West Transbaikalia in 2019 was realized as a one-year late summer with overwintering of larva. The most optimal population structure of the species is formed in a moistened meadow. An analysis of the timing of the phenological development of P. planipennis for 2019 compared to 2009 revealed an early onset of spring-summer activity of the species and an extension of seasonal activity, especially in the autumn period, by almost a month until mid-October.
KEY WORDS: Pterostichus planipennis, seasonal activity, sex-age structure, life cycle, WestTransbaikalia.
