Status in North Carolina
Natural Heritage Program Status: W-PK
Natural Heritage Program Ranks: GNR SU
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: This species is primarily Floridian and it may occur in North Carolina as only a stray; in South Carolina, it has been recorded only along the Coast near Charleston (Snyder, 2017). More sampling is needed to determine its status as a resident species, and more information is needed on its overall distribution, host plants, and habitat associations before its conservation status can be assessed.
