FEATURES
The sedge sprite is about one inch long; mostly dark, metallic-green, with a pale yellow-green thorax. They have a thin, pale stripe behind the eyes on the head and a blue spot on end of the tail. Females are like males, but their thorax is more yellow, and the end of the tail is greener. The sphagnum sprite (Nehalennia gracilis) is very similar and very subtle differences in the color of the abdomen separate them.  

BEHAVIOR
The sedge sprite is widespread and locally abundant in marshes and weedy ponds. Adults are often seen perching on plants close to water or flying low in the air, zig-zagging between plants. They fly from May to August in all but southern third of Illinois. They are not listed as a such but may be a vulnerable species in Illinois due to habitat degradation and loss.
