mating swarms

Mating swarms are dense aerial gatherings of insects—especially ants, termites, bees, and mosquitoes—that form specifically for reproduction.

Males and females congregate in flight, often triggered by weather conditions or time of day, to find mates.

The phenomenon is dramatic: Termite mating swarms descended on the porch lights.

After mating, males typically die while fertilized females disperse to establish new colonies.
