Tips to identify St. Francis satyr

Practical guide to St. Francis satyr habitats

St. Francis satyr

Our current effort with St. Francis satyr is focused on developing techniques for population monitoring.  Our longer-term goals are to determine the spatial structure of the butterfly's population, and in particular the role of riparian corridors in promoting dispersal between sites.   Limited in distribution to Ft. Bragg, North Carolina, St. Francis satyr (Neonympha mitchellii francisci) is one of the rarest butterflies in the US.  Its populations have been reduced by habitat loss, particularly by loss of wetland openings along streams where the butterflies persist.  These wetlands are maintained by disturbance, mainly caused by beavers that create and then abandon ponds.  Fire can also set back succession in these wetlands.

Our current work includes studies of:
  •   Effects of beavers on wetland plant communties, including on habitat quality for St. Francis satyr [more info...]
  •   Effects of habitat fragmentation and landscape boundaries on dispersal behavior  [more info...]
  •   Optimal approaches to monitoring long-term population dynamics
  •   Tests of food preferences for St. Francis satyr caterpillars [more info...]
Our research on St. Francis satyr is funded by DoD, Department of the Army, Endangered Species Branch at Ft. Bragg and the Strategic Environmental Research and Development Program
