Identification
Field Guide Descriptions: Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: (Ely, 1915)Technical Description, Immature Stages: (Ely, 1915)                                                                                 
Adult Markings: The thorax and forewings have a white ground color that is overlaid with ashy gray to light reddish brown coloration. The basal fourth of the wing is dark gray to reddish brown, and abuts a conspicuous, wide, pale gray fascia which extends obliquely across the wing posteriorly. The pattern beyond the large fascia is indistinct, but several smaller, whitish fasciae or blotches are often evident toward the tip of the wing. The cilia are light colored with two lines about the apex. The face is pale gray, and the crown of the head appears somewhat roughened with tufts above the eyes. The labial palps are white with a few dark scales toward the tips of the joints, and the second joint of the labial palpi has a distinct tuft. The antennae are pale yellow gray with brown annulations. The tibia and femur of the front and middle leg are reddish brown, and the tarsi are white with rusty brown annulations at the tips of the segments. The rear leg is yellowish to light tan.
Wingspan: 10 mm (Ely, 1915)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The leaf mine begins as a narrow, epidermal track on the lower surface, then eventually widens into an oval full-depth blotch that is usually formed at the leaf margin (Eiseman, 2019). The epidermis often tears due to the mine being formed when the leaf is still expanding. After exiting the mine, the larva feeds in a leaf cone made by bending down a single lobe and tying its edges to the underside of the leaf (Eiseman, 2019). In addition to skeletonizing the inside of the cone, the larva eats a row of small holes in the leaf along the outer margin of the cone. In some cases the leaf is skeletonized well beyond the cone.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Povolnya quercinigrella occurs throughout much of eastern North America from southern Ontario and Maine southward to Florida, and westward to Texas and Illinois. As of 2019, our records in North Carolina are from the lower mountains and Piedmont.

Habitats and Life History
Habitats: This species appears to use a variety of forested habitats that support oaks, including habitats that range from moist, alluvial floodplains to dry, upland forests.
Larval Host Plants: Povolnya quercinigrella specializes on oaks and was originally described from adults that were reared on Water Oak (Quercus nigra). Eiseman (2019) found mines of this species on other oaks, including Bear Oak (Quercus ilicifolia), White Oak (Q. alba), Northern Red Oak (Q. rubra), Post Oak (Q. stellata), and Black Oak (Q. velutina). - View
Observation Methods: Adults are attracted to UV lights, and larvae can be obtained from leaf mines on oaks.
