Nuptial flights in several ant species and their aerial aggregations (Hymenoptera, Formicidae)
Abstract:
Winged ants of the genus Myrmica, Leptothorax and Formica, were observed and caught as they gathered to swarm on the Wysoka summit (1052 m a.s.l.) in the Polish Carpathians, during the six years’ study. Variation in the male biased sex ratios of different species has been ascribed to multiple copulation by males, which remain in the swarming sites much longer than the females. The number of individuals caught and the swarming period changed from year to year, while the composition and participation of species differed in the particular stated capture sites remaining unchanged in the following years.
