State: Special Concern
At 1.8”-1.9” in length, this is New Jersey’s smallest striped emerald. Its eyes are bright metallic green and the face has a yellow stripe and green metallic patch. The thorax is green and metallic bronze with a lateral yellow stripe and dot and the abdomen is short. The female is similar and has a scoop-like ovipositor.
DISTRIBUTION AND HABITAT
The brush-tipped emerald was first recorded in New Jersey in 1982 and since then has been reported in a few locations in northern New Jersey. They inhabit open swamps and bogs with small streams flowing through them.
Larvae feed on aquatic invertebrates and adults on flying insects.
Adults are active from early June through the first week in August.
CURRENT STATUS, THREATS, AND CONSERVATION
The brush-tipped emerald is an uncommon dragonfly in New Jersey and therefore is considered a species of Special Concern in the state. Two threats facing this species are habitat modification and groundwater disturbance.
