the carmine colored flush on the bases of their wings. They 

 fly late in the summer (in Illinois they have been reported as

 companies on streamside shrubs. The nymphs live in mov- 

 ing water — in rapids, sometimes in the lapping waters of 

 lake shores. They are brown or green, without any color 

 pattern (Fig. 166). Fullgrown nymphs are one and a quarter 

 inches long. 



Lestes. — Nymphs of Lestes all live in ponds and small lakes 

 where they climb about among the plants of the shallow water. 

 They are very long bodied and slender with green and brown 

 bandings which camouflage them extremely well among their 

 surrounding stems and leaves (Fig. 167). Length of nymph, 

 three quarters of an inch.
