North American velvet ant species form one of the most intricate mimicry rings in the natural world, split into eight separate rings of mimicry.1

Males find females by smelling pheromones and by following their squeaking sounds. They carry the female in their jaws to a shaded, safe spot to mate.1

Females are believed to mate only once in their lifetime.1
