Taxonomy
Superfamily:
Geometroidea
Family:
Geometridae
Subfamily:
Ennominae
Tribe:
Ourapterygini
P3 Number:
91a1442
MONA Number:
6987.00
Comments: Eight species have been described in the genus, which ranges from Canada south at least to Costa Rica. Most species are found in our western states but one ranges from Costa Rica to North Carolina and northward.
Species Status: Specimens from North Carolina are similar to those from eastern US and eastern southern Canada. Variability in bar codes is minimum. There are synonyms of this species described from Guatemala and Costa Rica but the US records as displayed in Moth Photography Group would lead one to believe they are probably not conspecific with our species. According to Ferris (2010), thisoaria does not occur west of east Texas (95th meridian) and does not overlap with the western Antepione imitata.
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1948, as Sabulodes thisoaria); Ferris (2010)Technical Description, Immature Stages: Forbes (1948); Wagner et al. (2001); Wagner (2005)                                                                                 
Adult Markings: Sexes are highly variable, with different seasonal and sexual forms. Members of the spring brood are typically grayish brown or all pale, whereas in the summer brood, individuals are marked with bright yellow (Forbes, 1948). Males usually have a brown shade past the postmedian line, which is usually distinct; in the summer brood, males are typically two-toned. Females usually are more concolorous, with a less distinct postmedian but with one or two dark spots along that line at the inner margin (Forbes, 1948). Most forms have a distinct apical patch, but that is usually much more contrasting in the females.
Wingspan: 35 mm (Forbes, 1948)
Adult Structural Features: Genitalia are distinct in both sexes, differing from any species in our area likely to be confused with this Antepione
Structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The caterpillars are stick mimics that are highly variable in color. Like Prochoerodes and the two Tetracis species, the larvae are characterized by flattened heads, thickened segments, and prominent warts. Larvae of all three of these genera may be confused with one another, although the technical criteria described by Wagner et al. (2001) may help identify them.
Larvae ID Requirements: Identifiable from close inspection of specimens or by DNA analysis.
Distribution in North Carolina
Distribution: Most of our records come from the Mountains but there are also records from two Monadnocks in the western Piedmont, both of which have habitats similar to those found in the Blue Ridge

Flight Comments: Has two distinct broods per year
Habitats and Life History
Habitats: Our records come from a variety of montane habitats, including monadnock forests in the Piedmont, and both dry ridges -- including rock outcrops -- and mesic forests in the Mountains. The elevational range is also quite large, ranging from below 2,000 ft at Crowders Mountain in the Piedmont to over 5,000 ft in the Great Smokies, Great Balsams, and Grandfather Mountain.
Larval Host Plants: Larvae are reported from a wide variety of host plants including, but probably not limited to, alder, apple, cherry, ninebark, persimmon, sumac, viburnum (Wagner et al., 2001), and blackberry (Wagner, 2005). We do not have any feeding records in North Carolina. - View
Observation Methods: This species comes well to lights and may come to bait, although we have no records for it doing so. Occasionally flushed during the day.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 [S5]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: This species occurs widely throughout the Mountains, extending also into the western Piedmont. It is associated with both a large range of host plants and habitats within that region and appears to be quite secure within the state.
