No image for this species.
Taxonomy
Superfamily: Geometroidea Family: GeometridaeSubfamily: LarentiinaeTribe: HydriomeniniP3 Number: 91a0342 MONA Number: 7291.00 MONA Synonym: Hydria undulata
Comments: This species (Ferguson, 1955) was previously placed in the genus Hydria (Hodges et al. 1983), then later in Rheumaptera, before being returned to Hydria (Hausmann and Viidalepp 2012). The latest 2023 checklist of North American has returned it to Rheumaptera (Pohl and. Nanz, 2023).
Identification
Field Guide Descriptions: Covell (1984; as Hydria undulata)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Ferguson (1955)                                                                                 
Adult Markings: Rheumaptera undulata and R. prunivorata are two cryptic species that can only be reliably separated using genitalia. In western North Carolina they tend to separate to some extent elevationally, with R. undulata rarely occurring below 3,500' and R. prunivorata extending from the lower valleys to higher elevations where it overlaps elevationally with R. undulata. Thus, specimens from the lower valleys can generally be assigned to R. prunivorata with high confidence.
Adult ID Requirements: Identifiable only by close inspection of structural features or by DNA analysis.
