Identification
Field Guide Descriptions: Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1923)                                                                                 
Adult Markings: This is a distinctive species with a clayish-yellow head and palps that strongly contrast with the grayish-brown to dark brown forewings. The forewing ground varies from grayish-brown to dark brown and has slightly darker antemedial and postmedial lines that are often obscured by the dark ground. A small, triangular, clay-colored patch is often present along the costa in the subapical area. The hindwing is uniformly brown and a shade lighter than the forewing ground. The fringe of both wings tends to be weakly two-toned, with the base darker than the outer portion.
Wingspan: 15 mm (Forbes, 1923).

Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Despite being very common, the life history of this species has not been documented.
Distribution in North Carolina
Distribution: Loxostegopsis merrickalis is found in Mexico, the eastern and central U.S., and adjoining areas of southern Canada (Manitoba; Ontario; Quebec). In the U.S., the range extends from southern Maine and other New England states southward to southern Florida, and westward to Texas, Oklahoma, Colorado, Kansas, eastern Nebraska and the eastern Dakotas. We have records from all three physiographic regions, although this species appears to be absent from much of the northern Coastal Plain and the northern and southern mountains in the Blue Ridge.
