Leks and hilltopping in insects

摘要: Insects of many groups form mating aggregations on hilltops. Males some hilltopping species behave like certain classic lekking vertebrates, notably in their defense territories that are devoid resources useful to females but which visited by solely for mating. But even within a sample 11 insects found the same habitat central Arizona, there is considerable diversity with respect transferred mates males, degree males aggregated and territorial, extent can choose freely among males. Thus ‘hilltopping’ not single system type; although conform closely traditional definition lek, others very different. The ecological basis behaviour male appears linked differences population density, affect costs territoriality, nature female choice, little understood as yet.
