Taxonomy
Superfamily: Gracillarioidea Family: GracillariidaeSubfamily: LithocolletinaeTribe: [Lithocolletini]P3 Number: 330376.00 MONA Number: 833.00
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: Online Photographs: BugGuideTechnical Description, Adults: Braun, 1908.                                                                                 
Adult Markings: The following is largely based on Braun's (1908) original description based on 18 specimens from a site in Connecticut. The palps are whitish with dark sides, while the face is reddish ocherous. The head tuft is reddish ocherous with some whitish scales, and the antennae are dark brown above with paler bands. The thorax and forewings are brownish ocherous. Each forewing has four dorsal and three white streaks that are dark margined posteriorly. The first (basal) pair consists of a relatively long dorsal streak that parallels the fascia in the middle, and a much shorter costal streak. In some specimens these may nearly touch. The second pair is united to form a posteriorly angulated fascia in the middle of the wing. In some specimens dark shading extends from the angle of the fascia posteriorly between the third pair of streaks to the apex (it can be poorly developed in other specimens). The third pair of whitish streaks occur at about three-fourths and are relatively small and opposite each other. A fourth costal streak occurs near the apex and has variable amounts of dark dusting towards the reddish ocherous cilia. The hindwings and cilia are gray with a brownish tinge. The tarsi on the forelegs and middle legs are white with bold black markings. The hindlegs are white with reduced black marks relative to the other legs. This species is similar to C. bethunella, but can be distinguished by the prominent black markings on the legs.
Wingspan: 6.5-7.0 mm (Braun, 1908).
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larvae mine the upper side of the leaf and create a brownish blotch. The general shape varies from widely oval to more widely elongated. At pupation, the mine has a single, prominent ridge (Braun, 1908).
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Cameraria picturatella is most common in the northeastern US, including Maine, Connecticut, Massachusetts, New York, and New Jersey. We have only two records for North Carolina as of 2020.

Flight Comments: Populations are bivoltine and include both a summer and autumn brood.
Habitats and Life History
Habitats: Cameraria picturatella is restricted to habitats that support the host species (Morella carolinensis and M. pensylvanica). These include sand dunes and sandy flats, pocosins, wet savannas and pine flatwoods, sandhill seepage bogs, and other peaty or sandy-peaty wetlands (Weakley, 2015).
Larval Host Plants: Larvae feed on Morella (Robinson et al., 2010; Eiseman, 2019). The known hosts are Pocosin Bayberry (M. carolinensis) and Northern Bayberry (M. pensylvanica).
Observation Methods: The adults rarely visit lights and almost all records are based on either active mines, or adults reared from mines.
