Duration of development of males in colonies of Polistes dominula (Christ) (Hymenoptera,Vespidae: Polistinae) in the south of Ukraine

The relation between the duration of ontogenesis of Polistes dominula males and the social structure of their colonies was studied in July–August 2012. Males developing in successful colonies with a foundress passed through the later-instar larval and pupal stages more quickly than those in orphaned colonies. Successful colonies more often produced males with weakly melanized mesopleura as compared with orphaned ones. Males from the two categories of colonies did not differ in the head and wing size. The influence of mechanical stress and nutrition during larval development and the specific signaling behavior of the foundresses on the male phenotypic diversity in P. dominula is discussed.
