Taxonomy
Superfamily: Geometroidea Family: GeometridaeSubfamily: EnnominaeTribe: CaberiniP3 Number: 91a1119 MONA Number: 6711.00 MONA Synonym: Thysanopyga intractata
Comments: The genus Ilexia was created by Ferguson (2009) for the single species, I. intractata, which had previous been placed in Thysanopyga. It is a common member of the North Carolina fauna.
Species Status: Specimens from North Carolina have been barare similar to those from elsewhere in its range, with no significant heterogeneity observed
Identification
Field Guide Descriptions: Covell (1984; as Thysanopyga intractata); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Ferguson (2009)Technical Description, Immature Stages: Wagner et al. (2001)                                                                                 
Adult Markings: A medium-small reddish Geometrid with variable dark and pale markings. The species is distinct and should be readily identified from illustrations. It might initially be confused with Episemasia but that species is distinctly smaller, noticeably different in maculation and on the wing only in the spring.
Wingspan: 25 mm (Forbes, 1948)
Adult Structural Features: Males have bipectinate antennae and are smaller than females. The reproductive structures of both sexes are distinctive and can be used to verify identification
Structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Caterpillars are green with few distinguishing characters but have been the most common purely green caterpillars we have found on Ilex species.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Found statewide

Flight Comments: The species is active year long with adults being among the last species on the wing in the winter and first in the spring. Caterpillars are available throughout the year.
Habitats and Life History
Habitats: Near members of the genus Ilex virtually anywhere they are growing. We have records from maritime scrub habitats, peatlands, Longleaf Pine woodlands, floodplains, and dry ridges.
Larval Host Plants: We have found caterpillars commonly on Ilex opaca and I. vomitoria. They are probably present on other Ilex species as well. - View
Observation Methods: Adults are one of the most common species in light trap catches throughout the year in the Coastal Plain. Occasionally they can be flushed during the day but we have not seen them at bait. The caterpillars can be beat from the foodplants on any warm day (over 50 degrees) in the winter as well as all year long. They are very difficult to find once the leaves of I. opaca harden but persist on the other Ilex species.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: GNR [S5]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: This species is as widespread and abundant as are the hollies that it feeds upon. It appears to be quite secure within the state
