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.

longipennis
Blue Dasher
The Blue Dasher (Pachydiplax longipennis) is a common and widely distributed dragonfly in the skimmer family Libellulidae. It is the sole species in its genus. Adults are characterized by a blue pruinose abdomen, particularly in males, and are known as "perchers" that hunt from stationary positions. Males exhibit pronounced territorial behavior at breeding and feeding sites, with social dominance hierarchies influencing dispersal patterns. The species occurs throughout North America and into the Caribbean.
Scathophaginae
dung flies, yellow dung flies
Scathophaginae is a subfamily of predatory flies within the family Scathophagidae, commonly known as dung flies. The subfamily contains at least 30 genera and approximately 130 described species. Adults are frequently associated with dung and decaying organic matter, where they occur in large numbers. The group is notable for being predatory rather than coprophagous, with both adults and larvae feeding on other insects.
