Status in North Carolina
Natural Heritage Program Status: W3
Natural Heritage Program Ranks: GNR S3?->[S1S3]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: The existence of multiple records from one site, from both May and July, indicates that a resident population exists in that location, i.e., that this species is not simply a stray from the south. Almost no information exists on its distribution, abundance, host plants, and habitat preferences anywhere within its range, which limits our ability to assess its conservation status.
