Taxonomy
Superfamily: Geometroidea Family: GeometridaeSubfamily: EnnominaeTribe: MacariiniP3 Number: 910752.00 MONA Number: 6331.00 MONA Synonym: Semiothisa promiscuata
Comments: One of 25 species in this genus -- commonly known as Angles (as in angular, referring to the wing shape) -- that occur in North America; 17 have been reported from North Carolina. Promiscuata is included in the hardwood-feeding notata species group by Ferguson (2008), of which aemulataria and notata are the other members that occur in North Carolina.
Identification
Field Guide Descriptions: Covell (1984; as Semiothisa promiscuata)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Ferguson (2008)Technical Description, Immature Stages: Ferguson (2008)                                                                                 
Adult Markings: A pale gray or white species with a yellow to rust-brown head and the usual Macaria pattern of lines, spots, and subapical excavation on the outer margin. Very similar to M. notata in pattern but has a yellowish or brownish tint, particularly along the lines, which are gray in notata. Macaria aemulataria is also similar but smaller and more heavily dusted with brownish scales, including the basal area, which is usually clear gray or white in promiscuata. The large patch of spots on the subterminal line below the apex is usually larger in promiscuata, extending close to the bar that extends downward from the costal margin along the subterminal. That bar is also usually a brighter red-brown than in aemulataria and there is a strongly marked line on the undersides of the wings of the same color -- easily observed when the wings are held vertically. We recommend examining or photographing the hindwings to distinguish between the two species, since worn specimens can be difficult to assign to species.
Adult Structural Features: Unlike the other two members of the notata group, males in promiscuata have a swollen hind tibiae and a pecten on the third abdominal sternite, similar to most other species of Macaria (Ferguson, 2008).
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Larvae are distinctively marked with purple and green (Ferguson, 2008). Any Macaria larvae found feeding on Red Bud are likely to represent this species (see Ferguson, 2008, for details).
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Found primarily in the Mountains and Piedmont but rare in the Coastal Plain, being found in that region primarily in the floodplains and adjoining slopes of the brownwater rivers (Roanoke, Tar, Neuse, and Cape Fear).
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: Ferguson notes that promiscuata has two clear broods in Maryland and probably elsewhere. In North Carolina, it appears to be out during most of the growing season between late spring and late summer.
Habitats and Life History
Habitats: Redbud often grows on rich soils associated mafic or calcareous rock formations and we have a number of records of promiscuata from such habitats or from similarly rich mountain coves and floodplains. In the Coastal Plain, which is dominated by acidic, nutrient-poor sandy soils, records for promiscuata are essentially confined to brownwater river floodplains and adjoining slopes, where rich alluvial soils are carried down from the Piedmont and Mountains.
Larval Host Plants: Monophagous, feeding solely on Redbud (Ferguson, 2008).
Observation Methods: Comes well to 15 watt blacklights but we do not have any records from either bait or flowers.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G4 [S4]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: This species is something of a habitat specialist, occurring primarily in stands of hardwood forests growing on rich soils. As such, it is fairly local in occurrence but is nonetheless found fairly widely over the state. Currently, there are few known threats other than loss and fragmentation of its habitat units.
