view caption
Taxonomy
Superfamily: Noctuoidea Family: NoctuidaeSubfamily: NoctuinaeTribe: OrthosiiniP3 Number: 932785.00 MONA Number: 10502.00 MONA Synonym: Himella intractata
Comments: A single species genus restricted to eastern North America and found across North Carolina.
Species Status: Although specimens from North Carolina have not been examined, some from South Carolina have and match specimens from throughout eastern North America. There is no evidence of heterogeneity.
Identification
Field Guide Descriptions: Covell (1984; as Himella intractata); Beadle and Leckie (2012)Online Photographs: MPG, BugGuide, iNaturalistTechnical Description, Adults: Forbes (1954)Technical Description, Immature Stages: Wagner et al. (2011)                                                                                 
Adult Markings: A medium sized, brown, spring-flying moth, this species is readily identified by the series of black dots (usually 3) in the fold of the forewing. Once placed in Orthodes (Forbes, 1954), as were a host of other species now placed elsewhere, the exact relationship of this genus is uncertain but it appears to be closer to some species of Orthosia.
Adult Structural Features: Both male and female genitalia are distinct, particularly the deeply cleft valve of the male. The aedeagus tapers posteriorly making eversion of the vesica with its patches of cornuti very difficult.
Structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Caterpillar green with longitudinal white stripes, very similar to the caterpillar of Achatia distincta, characters separating the two undetermined to date.
Larvae ID Requirements: Identifiable only through rearing to adulthood.
Distribution in North Carolina
Distribution: Probably occurs throughout the Mountains and Piedmont but may be confined to brownwater river floodplains in the Coastal Plain.
County Map: Clicking on a county returns the records for the species in that county.
Flight Dates:
 High Mountains (HM) ≥ 4,000 ft.
 Low Mountains (LM) < 4,000 ft.
 Piedmont (Pd)
 Coastal Plain (CP)

Flight Comments: Univoltine, flying primarily in March and April
Habitats and Life History
Habitats: All of our records come from hardwood-dominated forests; no records come from Longleaf Pine, Peatland, or Maritime Forests, all of which have been extensively sampled in North Carolina. Both bottomland and upland stands of hardwoods are used, including in some semi-wooded residential neighborhoods.
Larval Host Plants: Polyphagous on a wide variety of woody plants, actual foodplant choices in North Carolina unknown.
Observation Methods: Adults come to light but the infrequency may be due to weak attraction. Wagner et al (2011) indicate adults do not come to bait but can be found at spring flowers.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: GNR [S4S5]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: Although we have relatively few records for this species, that is most likely due to its early spring flight. It feeds on a wide range of common host plants and has been found in a variety of forest habitat types. While more spring surveys are needed to confirm its distribution and abundance, it currently appears to be secure within the state.
