Subterranean termites are organized by a caste system with workers, soldiers, primary reproductives/swarmers, secondary reproductives, and finally kings and queens. Termites begin the life cycle by swarming. After winged males and females mate, they shed their wings and begin a new colony, becoming the “king” and “queen.” As king and queen, they are the sole reproducers. After the queen’s eggs hatch, the offspring assume the various roles of the caste. Primary reproductives eventually leave the colony to swarm, mate and form new colonies. Wingless secondary reproductives, however, never leave the colony and are present to support the queen. Workers are sexually underdeveloped and do not mate; instead, they are in charge of building tunnels as well as feeding other castes. Soldiers handle defense of the colony, using their large mouthparts to fight off predators. Queens may live up to 50 years under ideal conditions and produce tens of thousands of eggs in her lifetime. Workers and soldiers, on the other hand, live about 1-2 years.
