Waspish males

BEING male doesn’t count for much among social insects, unless you happen to be a wasp called Mischocyttarus mastigophorus from Central America. The males of this species spend much of their time chasing and even biting females, Sean O’Donnell of the University of Washington in Seattle reports in a forthcoming issue of Ethology. He says this is the first known instance of male dominance within an insect society. In temperate zones, males are only needed for mating and they die soon afterwards. M. mastigophorus colonies, on the other hand, thrive all year round and males live longer. O’Donnell speculates that this allows males to make multiple mating flights,
