The largest termite swarms generally occur in the spring time, prompted by warmer temperatures and spring rains. Termites continue to swarm during the summer and even into autumn, but later swarms are generally smaller than the early spring swarms.
Termite swarms usually occur during the daylight hours. Termites are not particularly good flyers, so swarm flights are usually brief. However, a strong wind can carry a swarm a considerable distance. Swarmers are equipped with two long, transparent wings that they shed soon after landing. Swarming is not the only way for termites to establish new colonies. As a colony grows in size, groups of foraging termites sometimes form satellite colonies, a process called "budding."
