Taxonomy
Superfamily: Pyraloidea Family: CrambidaeSubfamily: PyraustinaeTribe: PyraustiniP3 Number: 80a0850 MONA Number: 4973.10
Species Status: Ecpyrrhorrhoe puralis was introduced from southeast Asia into the eastern United States probably in the 1990s (Solis et al., 2010). It has since spread over much of the range of its host plant, the introduced Princess-tree (Paulownia tomentosa).
Identification
Field Guide Descriptions: Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Munroe (1976)                                                                                 
Adult Markings: This species resembles several of our Hahncappsia species, but is significantly larger, lacks dark shading in the subterminal area, has uniquely colored forelegs, and has very different male genitalia (Solis et al. 2010). The forewing has a yellowish-buff ground color with transverse lines that are yellowish-brown. The antemedial line is smoothly excurved. The postmedial line extends from the inner margin as a slightly waved and weakly oblique line, then angles outward at around one-third the wing depth to run parallel to the inner margin for a short distance. It then joins an outwardly bowed and denticulate region on the costal half. The reniform is shaped like a small arc and nearly touches the postmedial line. The hindwing is concolorous with the forewing. Both the antemedial and postmedial lines are relatively straight and incomplete. The forelegs are distinctively patterned, with an extensive region of yellowish-buff near the base that is followed by a patch of chestnut brown on an otherwise pure white ground color.
Forewing Length: mean = 12.8 mm (n = 14) for females; 12.5 mm (n = 10) for males (Solis et al., 2010).
Adult Structural Features: Solis et al. (2010) have images of the male and female genitalia.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larvae feed only on the Princess-tree (Paulownia tomentosa), which is an introduced tree from southeast Asia. The larvae are rather nondescript with a dull whitish color. Pupation occurs in a thin, whitish cocoon.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: This species is found in the eastern U.S. from Massachusetts and New York southwestward through the Appalachian region to central Florida and Alabama, and westward to Texas, Arkansas, Missouri, Illinois, Kentucky and Ohio. Populations have also been documented in Oregon (Solis et al., 2010). Local populations are patchily distributed due to their reliance of Paulownia tomentosa as a host plant. As of 2023, we have records from both lower-elevation sites in the Blue Ridge and the eastern Piedmont.

Flight Comments: The adults fly from April through September in different areas of the range. Southern population probably have two or more broods per year, while northern populations are single-brooded (Solis et al., 2010).
Habitats and Life History
Habitats: Local populations are patchy and centered around local populations of the host plant.
Larval Host Plants: The larvae feed only on the Princess-tree (Paulownia tomentosa). - View
Observation Methods: The adults are attracted to lights.
