Comments: Cameraria is a genus of leaf-mining micromoths. Many species are stenophagous and specialize on a small number of closely related host species. There are currently more than 50 described species in North America.
Identification
Field Guide Descriptions: Covell (1984)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Braun (1908)Technical Description, Immature Stages: Braun (1908)                                                                                 
Adult Markings: The following description is based primarily on that of Braun (1908). The thorax is saffron yellow to reddish brown, and on some specimens the dorsum may have a central whitish line. The upper head is similar, but somewhat lighter, and the face and palps are whitish. The antenna is closely annulated with brown, and the annulations often become obsolete toward the base. The ground color of the forewing is dull saffron yellow to reddish brown, and there are two short whitish, oblique, costal streaks just before and after the middle that are narrowly edged with black. A third short oblique costal streak is present near the apical fringe, but on some specimens may be masked by black dusting and represented as a series of small white spots. Along the dorsal margin, there is a narrow white streak that extends from the base to near the tornus. The streak often terminates or becomes indistinct before reaching the tornus. From there, it angles inward towards the third costal streak, and forms the inner margin of an extensive area of black apical dusting. Extensive black dusting is also often present from the tip of the second costal streak towards the apex. The cilia are yellowish gray, and the fringe often has a somewhat faint darker band through the middle region. The fore and middle tarsi are white and spotted with black, while the hind tarsi is mostly white. The hindwings are gray with lighter cilia. Braun (1908) noted that the amount of dark dusting in the apical third of the forewing is variable and in some individuals is poorly developed. In others it may be so extensive that it obscures to varying degrees the deflexed dorso-basal streak that extends from the tornus.

Cameraria conglomeratella resembles C. ulmella, but the latter is smaller, has a paler ground color on the forewings, has costal streaks that are slightly more oblique, and has dark annulations on the antenna that are restricted to the apical two-thirds. In C. conglomeratella the annulations extend along the entire length, although they are sometimes indistinct toward the base (Braun, 1908). This species is also closely resembles C. quercivorella, but the dorso-basal white streak on C. quercivorella extends only a short distance beyond the middle of the wing to produce a reddish gap between the dorso-basal streak and the oblique dorsal white streak.
Wingspan: 7.5-9 mm (Braun, 1908)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larvae mine the leaves of oaks and produce yellowish to brownish upper-surface mines. The frass is rather diffuse and is deposited centrally and away from the edges. Mines that we examined from Scotland Co. and Columbus Co. had blackish frass that was deposited centrally on the bottom of the mine. Most of the mines lacked a conspicuous crease. The larvae are blackish and pupate in the mine beneath a flat and nearly circular silken cocoon (Braun, 1908).
Larvae ID Requirements: Identifiable only through rearing to adulthood.
Distribution in North Carolina
Distribution: Cameraria conglomeratella is found in the eastern US from New Jersey to as far south as Florida, and westward to southern Wisconsin, Illinois, Oklahoma and Texas. As of 2021, our records are from xeric habitats in the Sandhills and vicinity.
