An alate is a winged reproductive of a social insect (especially ants or termites, but the term can also be applied to aphids and some thrips). Alate females are typically those destined to become queens (also referred to as gynes), whereas alate males are occasionally referred to as "drones" (or "kings", in the case of termites). However, the existence of reproductives that do not have wings necessitates a term to distinguish the winged from the wingless reproductive forms. This is an example of polymorphism associated with eusociality.
