Identification
Field Guide Descriptions: Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Hodges, 1974                                                                                 
Adult Markings: The following is primarily based on the description in Clarke (1941). This is a distinctive species that has a pale yellowish-gray to grayish-brown forewing, along with an elongated, curved, dark-brown to black streak at the middle of the wing that extends almost to the white discal spot. The antenna is fuscous with darker annulations. The labial palp is white with the second segment irrorated with blackish fuscous exteriorly. The third segment has basal and subapical bands and an apex that is blackish fuscous. A zone of gray to light brownish-gray scales covers the top of the head and thorax, then extends as a narrow band along the costal margin. The band sometimes terminates shortly before reaching the costa, but on some specimens extends all the way to the mid-costal region to produce a horseshoe shape. There are two small blackish-fuscous spots near the basal portion of the band. At the base of the wing that immediately adjoins the light band there is a dark patch or zone that lightens posteriorly until it grades into the ground color of the forewing. The remainder of the costal margin has a series of alternating dark and light spots or bars that are reduced in size along the termen. The legs are whitish with a series of dark blotches and bands along their length.
Forewing Length: 6.5-9.0 mm (Hodges, 1974)
Adult Structural Features: Clarke (1941) provides detailed descriptions and illustrations of the male and female genitalia.
Genitalia and other structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Although there are numerous adult records, almost no information is available on the larval life history and ecology.
Larvae ID Requirements: Identifiable only through rearing to adulthood.
Distribution in North Carolina
Distribution: Agonopterix curvilineella is found primarily in eastern North America, including much of southern Canada from Nova Scotia to Ontario and Manitoba. In the US, the range extends from the northeastern states westward to Illinois, Iowa, and Wisconsin, and southward to Alabama, Tennessee, and North Carolina. As of 2020, all of our records are from the lower elevations in the mountains.
