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 dark emerald has two distinctive pale yellow spots on its thorax and a slender abdomen. The length of its body varies from 1.7 to 2.0 inches. It is similar to the incurvate emerald and Kennedy's emerald.
Uncommon throughout Wisconsin, it ranges from Canada to northeastern United States. It is usually found at boggy spring-fed streams, bog pools, and alder swamps.
Mid-June to mid August in Wisconsin.
