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.
