Why do some ants have wings?

Focus-Science and Technology - - Q & A - TERRY CROFT, LV

The ants you nor­mally see scur­ry­ing around the gar­den are wing­less fe­males. They do all the work of the colony, but they are ster­ile. The fly­ing ants are the male drones and vir­gin queens that are pro­duced by the colony, once a year. Th­ese are sent out en masse, when the weather con­di­tions are right, to start new colonies.
