Range Map
Edward's Hairstreak possible range (light gray). Few state records.
Reason for SWAP Designation
SGCN (c).
At-risk, expert review or recent assessment.
This species has a global rank of G4 (apparently secure); however, it is vulnerable to possibly extirpated in the majority of its US range.
Threats
Loss of habitat and the use of pesticides are likely the main drivers of population declines.
Research and Monitoring
Statewide pollinator surveys have been completed by the USFWS HAPET team and NDSU.
Pollinator surveys should continue throughout the state to determine species range and population trends in ND.
Management Recommendations
- Develop pollinator habitat.
- Protect and manage high quality native prairie and oak woodlands.
- Develop connectivity between quality habitats.
- Reduce pesticide use.
