Identification
Field Guide Descriptions: Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Munroe (1976)                                                                                 
Adult Markings: In this species, the head, thorax and forewing are shining lead gray, with the head and thorax particularly shiny. The forewing is unmarked and is overlaid with black-tipped, whitish scales that are most concentrated on the basal two-thirds of the wing (Forbes, 1923; Munroe, 1976). The hindwing is also lead gray, but somewhat paler near the base. The fringe of both wings is concolorous with the wings.
Forewing Length: 8-10 mm (Munroe, 1976)
Adult Structural Features: Munroe (1976) has descriptions of the male and female genitalia.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larval life history is undocumented, although Terry Harrison (BugGuide) has reared the adults from a Collinsonia sp.
Distribution in North Carolina
Distribution: Pyrausta demantrialis is found in Mexico, the eastern and south-central U.S., and southern Ontario, Canada The range extends from Pennsylvania and Maryland southwestward through the Appalachian region to northern Florida, and westward to Texas, southern Arizona, Oklahoma, Kentucky, Indiana, and southern Michigan. As of 2023, all of our records are from the Blue Ridge.

Flight Comments: The adults fly from February through October in Texas, and mostly from June through September farther north. As of 2023, our records are from late-July through mid-September, with populations appearing to be univoltine.
Habitats and Life History
Habitats: Our specimens are from rich mesic woods in the Blue Ridge.
Larval Host Plants: The only documented host is a Collinsonia species (BugGuide), which suggests that Canada Horsebalm (C. canadensis) could be a host in North Carolina. - View
Observation Methods: The adults are attracted to lights.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: GNR [S2-S3]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: This species appears to be uncommon in North Carolina and restricted to the Blue Ridge, with only five site records as of 2023. It appears to prefer rich woods with circumneutral soils.
