genus: Macrothemis


Three species are known to North America. These are medium sized dragonflies and usually slender in appearance.  The thorax is narrow, the dark brown or black abdomen is thickened at the base and slender at the middle segments and can vary in shape depending upon species. It is generally adorned with small yellow spots or 2 larger spots on segment.Wings may develop brown bands at the base or on the tips, depending upon the individuals age and sex. Coloration similar in both sexes.

In many species, individuals of both sexes sometimes gather in open areas and fly together for awhile, moving slowly and with "small leaps" along short stretches of water.

Sylphs have been known to breed in flowing waters, making them different from most other skimmers.  They prefer clear rocky streams and rivers.
