Mating root-aphid ants, the queen carrying a mealybug in her mandibles. Acropyga live nearly entirely by consuming secretions of root-feeding mealybugs, and the mealybugs depend on the ants for dispersal and protection. When young queen ants leave the nest to mate and start new colonies, they take a mealybug with them. Portal, Arizona, USA
Prenolepis imparis is the first ant to hold mating flights every year in temperate North America. Alates wait out the winter and emerge on the first warm spring days. This photo was taken in early March. Urbana, Illinois, USA
