Taxonomy
Superfamily: Geometroidea Family: GeometridaeSubfamily: EnnominaeTribe: AzelininiP3 Number: 91a1242 MONA Number: 6755.00
Comments: One of nineteen species in this genus that occur in North America north of Mexico (Poole, 1987; Pohl et al., 2016), four of which have been recorded in North Carolina
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Structural Features: Males can be distinguished by the wide, truncate tips of their abdomens; in females, the tip is bluntly rounded and a short, conical ovipositor is usually visible. In males, the eighth sternite is bilobed, the features of which are useful for identifying our three members of this genus. In honestaria, the lobes are narrow but rounded at the tip and are separated at their base by a u-shaped gap. In ancentaria, the lobes are wider and more-or-less diverging at the tip and separated by a much narrower cleft at the base. In morrisonaria, the two lobes are widely separated, strongly bifurcated at the tip, and with the outer process somewhat curved (see illustrations in Poole, 1987 and on the Moth Photographers Group website). Male and female genitalia are also distinctive.

Habitats and Life History
Habitats: We have records from high elevation forests, including the summits of Mt. Mitchell, Clingman's Dome, and Grandfather Mountain, but also from cove forests and riparian forests at lower elevations, e.g., New River State Park ad Stone Mountain State Park.
Larval Host Plants: Larvae feed primarily on conifer species. Poole (1987) lists Fir, Spruce, and Hemlock. Wagner et al., 2001) additionally lists Pine and mentions that it has also reported from birch and other hardwoods but possibly in error. - View

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 S3S4
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 associated with Hemlock Forests and Spruce-fir Forests, all of which are under attack from invasive exotic insects and are likely to become even more stressed due to climate change.
