hinged termites and ants . They are making their 

 spring appearance and are causing concern to 

 homeowners. They can be distinguished from each 

 other rather easily. A flying termite is always 

 black. A flying ant may be black, yellow, tan, 

 or almost red. The back wings of an ant are 

 shorter than the front wings . The two pairs of 

 wings on a termite are of equal size. An ant has 

 a constricted, or narrow, waist just behind the 

 wing-bearing section of the body. The termite 

 has no such constriction. The antennae of ter- 

 mites are straight, those of ants are elbowed. 

 The diagram shows the major differences.
