This paper presents the first description of the life cycle of Cinara mordvilkoi and alary dimorphism of its males. There are 3 phases in its life cycle and during the course of a year 10 generations of parthenogenetic females are produced. The durations of development of subsequent generations over three years were recorded. C. mordvilkoi was observed to change its feeding position on its host from leaves to roots throughout the year. In the third year of this study both winged and wingless males were recorded. The fundatrix, oviparous female and the apterous and winged males are described.
