Range Map
Mulberry Wing possible range (light gray). Very few state records.
Reason for SWAP Designation
SGCN (a). Regionally or globally imperiled.

Though there are very few historical records in the state, it is considered Imperiled and a species of concern.
Threats
As a wetland specialist, this skipper is highly threatened by the drainage of wetlands and loss of wetland habitat across its range.
The use of herbicide and pesticides may also be a factor in 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 presence in ND.
Management Recommendations
- Protect and manage native wetlands.
- Minimize draining and developing wetland habitats.
- Include its host plant, Carex stricta, and other Carex species in wetlands plantings.
- Include nectar rich plants in wetland plantings.
