Abstract

The composition of 13 populations of Adalia bipunctata L. collected in France and Italy was studied. The proportion of black individuals varies from 7.7% to 84.7%. Comparison of the composition of color forms with climatic parameters of habitats showed that the proportion of black individuals in the Italian populations negatively correlates with the mean temperatures of the period of reproduction of beetles (May–July). No such relationship was found for the more Northern populations living in France.
