genus: Macrothemis

Sylphs

Three species are known to North America. These are medium sized dragonflies and usually slender in appearance.  The thorax is narrow, the abdomen is thickened at the base and slender at the middle segments and can vary in shape depending upon species.

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