Taxonomy
Superfamily: Geometroidea Family: GeometridaeSubfamily: LarentiinaeTribe: LobophoriniP3 Number: 910479.00 MONA Number: 7638.00
Comments: The genus currently includes four species found in North America, three of which occur in North Carolina.
Species Status: Whether or not C. angulineata and C. limitaria are separable by bar codes is unknown because the samples submitted are often misidentified. If they are separable, it will be by less than the usual 2% minimum.
Identification
Field Guide Descriptions: Covell (1984)Online Photographs: MPG, BugGuide, iNaturalistTechnical Description, Adults: Forbes (1948)                                                                                 
Adult Markings: This species can be distinguished from C. limitaria with practice but the characters of the vertex and frons are reversed in Covell's Field Guide but correct in Forbes. C. limitaria is rather uniformly brownish without a contrasting pattern. Most importantly, it is usually larger than C. angulineata and the wings are more pointed. C. angulineata usually has a distinct pattern often overlaid with a greenish tint but never as contrasting as C. atroliturata. There is a line between the eyes on the vertex and the frons is white in males but in females the brown scaling of the upper frons can result in a spectacled pattern. The wing tips are rounded not pointed as in C. limitaria but the degree of pointedness is sex dependent making females more likely to be misidentified.
Adult Structural Features: Hind tibia of male with hair pencil. Wing apices rounded. Slightly smaller than the other two species. The aedeagi and valves are similar in C. angulineata and limitaria but the sclerotized anal edge on the valve is pointed not blunted as in C. limitaria. The sclerotized projection onto the face of the valve is smaller than in C. limitaria. In females the ostium is triangular and incised distally (it is not incised in limitaria) and the ductus bursae is much shorter than that of C. limitaria.
Structural photos
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].
Larvae ID Requirements: Identifiable only through rearing to adulthood.
Distribution in North Carolina
Distribution: This is the only species outside the mountains and is the most common species until one reaches higher altitudes.
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: Single brooded in the early spring as are all members of the genus. The flight season is 3-4 weeks at a single location but by changing altitude it can be found for a longer period.
Habitats and Life History
Habitats: It occurs in hardwood habitats but these usually contain some evergreens so its requirements are really unknown; found up to 4500 feet.
Larval Host Plants: Due to confusion with limitaria, the caterpillar and its foodplants are unknown. Captive females will probably lay eggs readily and they could be offered a mixture of common hardwood and evergreen foodplants. Once the larval image is known and a food preference determined, one could look for caterpillars on the specific plants.
Observation Methods: The species comes readily to lights but not to baits.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 [S4]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: Found here and there usually as singletons in the Coastal Plain. In the mountains it can be quite common and often flying on cold nights when few other species are active.
