Winged termites often are confused with ants, especially carpenter ants. There are several distinguishing characteristics. In termites , the abdomen is broadly attached to the thorax or leg-bearing portion of the body. Ants have a pinched-in, narrow waist. Termite antennae are straight and when examined closely, look like a string of beads.
Ant antennae are bent or elbowed.
Worker and soldier castes are wingless and unpigmented. They usually are not seen unless there is a break in the nest structure or connecting tubes. Soldiers are distinguished by their larger heads, which may be hardened and dark in color. Their jaws are larger than those of workers.
