Ants

Black garden ant

These insects are black or dark brown and nest in soil, lawns, at the base of walls or under flat stones. Ants are social insects; they live in colonies that consist mainly of workers – sterile, wingless females.

In July and August, winged males and females emerge for mating flights. They are about twice the size of the workers. Climatic conditions determine when these flying ants appear, and all the nests in any one area will generally erupt at the same time.
After mating, the males die, while females shed their wings and seek suitable nesting sites. Birds take many ants during these mating flights and only a few females (queens) survive to start new colonies.
