Fringed Dart
Eucoptocnemis fimbriaris (Guenée, 1852)

Threats [-]
Elimination and fragmentation of habitat by commercial and residential development are threats to the fringed dart. In addition, fire suppression and allowing natural succession may eliminate suitable habitat, yet improperly planned fires could wipe out populations.

Conservation Strategies and Management Practices [-]
Maintaining suitable habitat is the main management need. Although the fringed dart occupies a variety of habitats in addition to pine barrens, several of the natural communities that it occupies in New York State require periodic fire or mechanical management to maintain the natural community. A recent study that was conducted to investigate the effect of prescribed burns on moths in scrub-oak barrens on Long Island found that the abundance of species that feed on forbs, such as the fringed dart, did not increase after burns. This was attributed to the fact that fires in the studied habitat removed the biomass of the shrub layer but did not open up new areas, which would have led to increased forb abundance (McGuinness 2009). In 2005, a fringed dart was captured in an area of a pine barrens habitat that had burned during a wildfire in 1995 (McGuinness 2006). During prescribed burns, some areas should be left unburned to provide refugia for the fringed dart and allow for its later recolonization of burned areas. In addition, it would be beneficial to restrict ATV use and minimize lighting in order to maintain dark sky conditions in occupied areas.

Research Needs [-]
Research is needed to identify larval foodplants, in order to better define suitable habitat.
