Alternative reproductive strategies in Formica lugubris Zett (Hymenoptera, Formicidae)
Ethology Ecology and Evolution
Sp. Iss. 1
A long term study on the reproductive strategies of Formica lugubris (Formica rufa group) has revealed many new important facts. Within a supercolony the sex-ratio is strongly female biased. Some of the sexuals mate on the nest surface, whereas others fly from the nest. Those sexuals participating in flights aggregate in particular meadow sites (mating places). On these places females attract males by releasing a sex pheromone.
