- A continuing threat of infestation to forest stands by the nun moth (Lymantria monacha) and difficulties in predicting the mass occurrence of this species necessitate precise analyses of the changes in the nun moth abundance over time and space. The paper provides a comparative analysis of the abundance of larvae and butterflies on the same control plots in the years 1996 – 2001. The observations demonstrated that the changes in the abundance of larvae and butterflies – males were directly proportional. A distinct difference was found only in 2001. Inspections indicated a relatively high number of larvae and a significant decline in the number of butterflies – males as compared with the previous year. Such differences in the abundance of these two developmental stages may have resulted from the high mortality of individuals during their development and give a picture of different development of this foliophage population.
