66. AMPHIAGRION Selys 
These are small stout-bodied black and red damselflies that frequent 
reedy, spring-fed swales. The abdomen is rather short and thick. The 
wings are hyaline. The stigma is notably longer in the front than on the 
hind margin, especially in the male, and the costal area of the wing tips 
beyond the stigma is richly charged with cross veins. 
The sexes are colored alike except that the red of the male becomes 
brighter. The color changes with age are considerable. Size varies 
greatly also and a number of variations have been described. The 
species is wide ranging within our limits; frequenting meadow rivulets. 
Adults are found only in the vicinity of their native streamlets where 
they flit about among the stems in or overhanging the water. 
The nymphs (Ndm. ’03, p. 248) have a thick set body and remarkably 
prominent hind angles on the head. 
In our fauna there is a single variable species.
