Superfamily: Tineoidea Family: TineidaeSubfamily: NemapogoninaeP3 Number: 300118.00 MONA Number: 272.00

Identification
Field Guide Descriptions: Leckie and Beadle, 2018 Online Photographs: MPG, BugGuide, GBIF, BOLDTechnical Description, Adults: Dietz (1905)                                                                                 
Adult Markings: The following is based primarily on Dietz's (1905) original description of the species. The head and thorax are dark brown and the antenna pale ochreous fuscous. The ground color of the forewing is a deep rich golden brown and traversed by white longitudinal lines. The extreme costa and dorsal margins are pale, and there are two or more narrow white lines along the costal margin that interconnect to varying degrees. Two other narrow white lines arise from middle of base and run parallel almost to the apical cilia where they converge with a curved white line that originates on the dorsal margin near the beginning of the dorsal cilia. These continue to the cilia where they split into two white lines. The terminal fringe is whitish on the dorsal half, and dark brown on the apical half, with two white lines within. A thin line of scattered, brown scales occurs in the middle of the fringe. The hindwing and cilia are gray. This very distinctively marked species is unmistakable.
Wingspan: 10.0-14.5 mm (Dietz, 1905).
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larva are known to feed on fungi, but almost all aspects of the life history are undocumented.
Distribution in North Carolina
Distribution: Nemapogon rileyi is found across much of the eastern US and adjoining areas of southern Canada (Ontario). The range extends from the northeastern states south and westward to Florida, southern Alabama and Texas. Farther north, population occur as far west as Wisconsin. Populations are most common in the Coastal Plain and lower Piedmont, and relatively rare in many interior regions. As of 2020, our records for North Carolina are from the Costal Plain and Piedmont.
