The medium-sized, dark brown striped emeralds have some pale markings on the thorax and abdomen, black legs, clear wings and brilliant green eyes. The thorax has a metallic bronze-green sheen and the abdomen is dark metallic black-green. Most species are uncommonly seen, but this may be largely due to their secretive nature. When flying, most species look alike which is why in-hand identifications of their anatomical features are often needed.
This small, stocky, dark dragonfly has a few yellow markings on the side of the throax and the abdomen. The face is yellow. The brush-tipped emerald has a short abdomen, especially in the males. The length of the body varies from 1.6 to 2.0 inches. Juvenile females have orange-tinted wings, amber-tinted wing bases, and tan ovipositors.
Common throughout southern Canada and northern United States, it prefers lake outlets, pond outlets, and small streams that go through bogs, fens, or marshes. In Wisconsin, it has been found in scattered areas, mostly in northern counties.
Mid-June to mid August in Wisconsin.
