If these appear inside a structure, an infestation is present. Before a new colony is formed they break off their wings, leaving only a small stub where the wings were attached. 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.
