Taxonomy
Superfamily: Gracillarioidea Family: GracillariidaeSubfamily: LithocolletinaeP3 Number: 33a0245 MONA Number: 824.00
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 Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Braun, 1908.Technical Description, Immature Stages: Braun, 1908; Eiseman, 2019.                                                                                 
Adult Markings: The following is mostly based on Braun's (1908) description of adults. The face and palpi are whitish, while the antennae are whitish ocherous with dark brown annulations. The head tuft is reddish orange, and the thorax and forewings are deep reddish orange. At the base of the wing there is a faint, silvery streak with a black margin posteriorly that extends from the margin to the fold. This is followed by two straight, oblique, and roughly parallel silvery bands that are black margined posteriorly. The first is at the basal fourth of the wing, and the second about midway. At three-fourths, there is a costal and dorsal streak with black posterior margins. The dorsal streak is longer and curved rearward, while the costal one is shorter, straight, and often reduced to a spot. At the beginning of the costal cilia there is a short apical streak that is dark margined. The cilia are reddish, but become gray at the tornus. The hindwings and cilia are reddish gray, and the abdomen is dark gray above and ocherous gray beneath. The tarsal joints of the legs are white and tipped with black, but less so on the hindlegs. Although C. hamameliella is very closely related to C. aceriella, C. hamameliella differs by having deeper and more reddish color on the tuft and wings. The hind tarsi of C. hamameliella are also usually tipped with black, whereas in C. aceriella they are either faintly blackish tipped or entirely pure white. There are exceptions to these general trends, and specimens are best identified by rearing or barcoding.
Wingspan: 7 mm (Braun, 1908).
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Larvae mine the upper leaf surface and produce a whitish blotch that usually has a darker central area. The mature blotch is roughly circular or slightly oblong in shape. Larvae in the first brood pupate during the summer beneath a flat silken cocoon (Braun, 1908). Larvae in the second brood construct overwintering niduses which are visible through the epidermis as white rings (Eiseman, 2019). Individuals either overwinter as pupae, or as larvae and pupate the following spring. The adults emerge after the spring leaf-out.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Cameraria hamameliella is widely distributed in eastern North America, including southern Ontario, southern Nova Scotia, and much of the eastern US where the host species are found. As of 2022, our records from North Carolina are mostly from lower elevation sites in the mountains.
