The sex and age structure of the population, developmental biology, and parental care were studied in Pterostichus anthracinus from the floodland plain of the Desna River. Analysis of the data demonstrated that the life cycle of P. anthracinus can be characterized as a spring-summer one with the summer development of larvae and wintering at the adult stage. Reproduction ends in the first ten days of August. Development from eggs to adults lasts for 29–33 days. P. anthracinus possesses the advanced type of parental care that is characterized by active guarding of egg clutches till emergence of larvae. Original Russian Text ? F.N.
