The soldiers have elongated yellowish heads with large jaws and are about the same size as adult workers. They protect the colony in case of invasion. During this time, swarms may be found inside infested structures. Sometimes, their shed wings are the only evidence that termites are present. Because winged termites often are confused with winged ants, it's important to know how to tell the difference.
Ants have narrow, wasp-like waists, while termites have broad waists.
Also, the wings of an ant are about the same length as its body, but a termite's wings are about twice the length of its body. Termite tubes are another danger signal to watch for. Because they prefer dark, moist conditions, termites make these earth-colored tubes primarily as protected runways from the earth to the wood they feed on. They also may serve as swarming exits for winged termites. Wood attacked by termites has channels or passages coated with an earth-like material.
