Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Brown and Jaeger (2014)                                                                                 
Adult Markings: The following is based on the original description by Brown and Jaeger (2014). The vertex is brownish orange and becomes orange white near the frons. The second segment of the labial palp is yellowish white or orange gray, with scattered light brown scales near the middle, and light brown distal scales that extend ventrally beyond the apex of the pale brown third segment. The thorax and tegulae vary from pale brown to pale brown mixed with orange. The basal half of the wing is concolorous with the thorax and is pale brown intermixed with variable amounts of orange. A rounded spot is present before the middle of the inner margin, and the median fascia is faintly defined and lacks distinct margins. It is dark brown or brownish orange and extends from the middle of the costa to the tornus. The ocellus is distinct and consists of two transverse silvery bars, with the basal bar nearly twice as long as the apical bar. A silvery spot near the tornus, along with the transverse bars, encloses an orange area with two or three brown longitudinal lines. Salt-and-peppered scaling forms a large spot costal to the ocellus and a wide band on the apical margin from the apex to the tornus. The apical third of the wing is orange on the costa, and the costa has 5-9 well expressed strigulae with a narrow silvery stria originating from each pair. The hindwing is uniformly light brown. Eucosma paregoria is distinct from our other Eucosma species by having a forewing with orange scales in the apical third that surround a distinct ocellus that is bordered on the costal side by a patch of salt-and-pepper scales.
Forewing Length: 8.3-10.8 mm (Brown and Jaeger, 2014)
Adult Structural Features: Brown and Jaeger (2014) provide illustrations and descriptions of the genitalia. In the male, the uncus is reduced to a setose, rounded lobe with a notch at the apex. The socii are long, pendant, and setose from beyond the base to the apex and taper in the distal fourth. The gnathos is sclerotized basally, and membranous and fused medially. The phallus is long, tapered, and has 17–20 cornuti. The anellus closely surrounds the base of the phallus, while the medial flanges of the caulis are fused from the juxta to the anellus. The valve has the cucullus well defined by a deep ventral incurvation of the neck, which has a medial flange projecting ventrally. The sacculus is ventrally rounded near the neck, and the cucullus has spiniform setae on the ventral two-thirds.

In the female, sternum VII is rounded and rugose anteriorly. Tergum VIII is sparsely setose laterally, with a row of setae on the dorsoposterior margin and lacks scales. The papillae anales lack a deep posterior cleft, are moderately setose, face laterally, and have narrow ventral faces. The lamella postvaginalis has a straight posterior margin, concave lateral margins, and a posterior area and adjacent membrane with about 20 small setae. The lamella antevaginalis is reduced to a narrow, membranous band, and the ductus bursae is short with a sclerotized ring posterior to the inception of the ductus seminalis. The signa are flattened, apically rounded, and subequal in size.
Immatures and Development: The larval life history is undocumented.
Distribution in North Carolina
Distribution: This species was described in 2014 and the range is poorly defined. Brown and Jaeger (2014) identified specimens from Iowa, Arkansas, Illinois, Louisiana, Missouri, and North Carolina. As of 2022, our two records are both from the Piedmont.
