Identification
Field Guide Descriptions: Beadle and Leckie (2012)Online Photographs: MPG, BugGuideTechnical Description, Adults: Braun (1908); Eiseman (2019)Technical Description, Immature Stages: Braun (1908); Eiseman (2019)                                                                                 
Adult Markings: The following description of the adults is based primarily on Braun (1908). The face and palps are white, while the antenna is whitish with brown annulations above. The ground color of the thorax and forewing is reddish brown. The head tuft is whitish with some reddish brown laterally. The ground color of the forewing is reddish-brown, and is overlain with several white streaks or fascia with varying levels of black scales on their posterior margins. Two white fascia are present; one at about one-fourth, and the second at the middle of the wing. Each are boldly margined in black posteriorly. The first fascia is slightly concave outwardly on the fold, then extends obliquely to the costa. The second fascia at about the middle of the wing is slightly oblique. At the base of the wing there is a short white streak, often with a few black marginal scales, that extends from the inner margin to no more than the middle of the wing base. At about three-fourths, there is a conspicuous white streak with a black posterior margin. The streak projects from the inner margin rearward, and the terminus approaches a short, straight sub-costal streak that is often reduced to a spot or small patch. Just anterior to the sub-costal streak or patch, there may be a second faint costal patch or spot. Some of the scales in the apical third of the forewing are tipped with brown and produce varying levels of brownish dusting (most evident on unworn specimens). The cilia is ocherous and the marginal line in the cilia is brownish. The hindwing is grayish ocherous. The front and middle legs are banded black and white above, while the rear legs are whitish with a faint darker mark or two sometimes evident near the tarsal joints. Cameraria ostryarella closely resembles C. corylisella, but the later lacks the brownish dusting on the apical third of the wing. In addition, the dorsal streak at about three-fourths is strongly oblique in C. ostryarella. In C. corylisella the dorsal streak is nearly erect and runs nearly parallel to the mid-wing fascia. Cameraria aceriella is also similar, but lacks both the dark dusting on the apical third and the marginal line in the cilia.
Wingspan: 6-7 mm (Braun, 1908)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larvae form irregular upper surface blotch mines that tend to have dark brown interior regions and lighter edges when fresh. The mines are often communal, with as many as five larvae feeding together in a single mine (Braun, 1908; Eiseman 2019). In some instances, these may reflect the fusion of individual mines to form a larger communal mine. Local populations are bivoltine. Larvae in the first seasonal brood pupate within the mines, but do not produce circular silk-lined chambers (niduses). Larvae in the second, overwintering brood do construct niduses. Each nidus has a circular narrow ridge on the upper epidermis and a convex projection on the lower leaf surface (Braun, 1908; Eiseman, 2019). Occupied mines that we have found in North Carolina typically contain from 1-5 larvae, with most having either one or two larvae. The mines varied in shape from being somewhat globular to more elongated. Larvae that were collected in September produced circular niduses. They presumably overwinter in these, then pupate the following spring.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Cameraria ostryarella occurs in eastern North America from the northeastern US, westward to Ontario, Quebec, Michigan, and Iowa, then southward to Kentucky and North Carolina. As of 2020, our records for North Carolina are from the lower mountains.

Flight Comments: Local populations appear to be bivoltine, with adults active from April-August.
Habitats and Life History
Habitats: Local populations are strongly affiliated with the host plants, American Hop-hornbeam (Ostrya virginiana) and American Hornbeam (Carpinus caroliniana). Ostrya occurs in rich woods with circumneutral soils, while Carpinus is common along stream banks, in floodplains, and on moist slopes.
Larval Host Plants: American Hop-hornbeam and American Hornbeam appear to be the primary hosts. As of 2021, all of our five site records for North Carolina were based on leaf mines on American Hop-hornbeam.
Observation Methods: We recommend searching for the rather conspicuous leaf mines on Ostrya and Carpinus during the late spring and summer months. We encourage individuals to rear and photograph the adults. The adults occasionally visit lights that are set up in the vicinity of the host plants.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: GNR SU
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: This species was only recently discovered in North Carolina, which likely reflects the fact that little effort has been put forth to document leafminers within the state.
