Chromagrion conditum
Aurora Damsel
Chromagrion conditum, commonly known as the Aurora Damsel, is the sole species in its genus. This small damselfly is distinguished by its striking coloration with bright yellow-green thorax and blue abdominal markings in males. It inhabits forested streams and seeps across eastern North America. The species is notable for its early spring emergence, often appearing before most other damselflies in its range.
Cordulegaster erronea
tiger spiketail
Cordulegaster erronea, the tiger spiketail, is a large, uncommon dragonfly in the family Cordulegastridae. It is a habitat specialist requiring small, pristine, spring-fed forest streams with muck bottoms and overhanging vegetation. The species has a long larval period estimated at 3-4 years and a brief adult flight period of approximately 2-3 weeks in early summer. Radio-telemetry studies in New Jersey have revealed limited adult movement, with individuals typically remaining within 100-200 meters of natal streams and showing strong site fidelity.

Bent Forestfly
Ostrocerca prolongata, commonly known as the bent forestfly, is a species of spring stonefly in the family Nemouridae. It was described by Claassen in 1923. The species is found in eastern North America, with records from the northeastern United States and adjacent Canada. Like other members of Nemouridae, it is associated with forested stream habitats.
