Which caste of termites are referred to as Alates?

The term "Alates" specifically refers to the winged reproductive caste of termites. These are the individuals that leave the colony during a swarm, which typically occurs during certain environmental conditions, usually in spring or early summer. Alates are essential for the reproduction of termite colonies, as they are the ones that mate and establish new colonies.

When the environmental cues are right, often during warm, humid conditions, Alates will take flight in groups to disperse and find new locations where they can establish themselves as a colony. The ability to fly and establish new colonies is critical for the survival and spread of termite species. In contrast, workers are primarily responsible for foraging, feeding the colony, and taking care of the young, while soldiers protect the colony from predators. Secondary reproductives can also contribute to reproduction within the colony but are not the primary swarming individuals that represent the term Alates.
