The boghaunters are the smallest emeralds in the family with little metallic coloration. Their bodies are thinly haired. The abdomens in males are constricted just below the bases. The boghaunters are rare inhabitants of northeastern bogs, with two species in North America.
This small black dragonfly is one of the rarer emeralds. The body varies from 1.1 to 1.4 inches in the length. The abdomen has white rings near the base of the abdomen. The face is dark brown with bright green eyes for males and gray eyes for females. The ebony boghaunter is similar to the ringed boghaunter. However, the ringed boghaunter has orange rings on most of its abdomen and an orange-brown face.
Not common throughout northeastern United States and southeastern Canada, it prefers forested sphagnum bog pools and fens, often the same places as the ringed boghaunter.
Early May to early July in Wisconsin. The flight season tends to be short, depending on its locations.
