This termite is known to swarm in spring, but small flights can occur at any time of the year. Swarming is the visible means that termites use to establish new colonies. As the colony grows, specialized castes are produced for the different tasks required. One caste produced is the workers. Another caste is the soldiers. And a third caste is the reproductives. Primary reproductives swarm and start new colonies. They are called alates or swarmers. Although thousands of primary reproductives may be produced each year, they all leave the nest. Supplementary reproductives, on the other hand, can become reproductive only in the colonies in which they were born. They assist the primary king and queen in population growth of the colony.
