Technical Description, Adults: Braun, 1908.

Adult Markings: The following is Braun's (1908) description based on specimens from Cincinnati, Ohio. The antennae are pale ocherous and ringed with dark coloration beyond the basal third. Several joints toward the tip are also dark. The palpi and face are shining white, and the head tuft is whitish above and golden toward the sides. The thorax and forewings are ocherous. A white stripe on each side of the middle of the thorax is continuous with a very oblique curved white streak at the inner angle of the forewing. This streak, which is sometimes dark margined behind, extends to the fold and is usually prolonged along the fold to unite with the first dorsal streak. The first dorsal streak begins at the basal fifth, is oblique and curved, and extends slightly more than halfway across the wing. The second dorsal streak, at about the middle of the dorsal margin, is also oblique and curved, and near the costa its apex meets that of the first costal streak, which is short, oblique and placed slightly beyond the middle, thus forming an acutely angled, interrupted fascia. The second costal streak at the apical fourth is sometimes almost overlaid with black scales. Above the dorsal cilia is a long oblique white streak. All the streaks are dark margined externally. The apical portion is white and dusted with black. There is considerable variation in the extent of the black dusting, which sometimes extends to the tornus. The marginal line in the cilia is brownish ocherous and the cilia is pale ocherous. The hindwings are pale grayish ocherous with pale ocherous cilia. The abdomen is gray above and pale ocherous below, and the anal tuft ocherous.

Features of the forewing that help to distinguish this species from other Cameraria include the presence of oblique costal and dorsal streaks, an oblique white streak or patch at the base of the dorsal margin, and two fasciae that are distinctly angulated. Braun (1908) has color illustrations of species in the eastern US that are useful for comparing closely related forms.

Wingspan: 5-7 mm (Braun, 1908).

Adult ID Requirements: Identifiable from good quality photos of unworn specimens.

Immatures and Development: Braun (1908) found the mines to be very common on Sugar Maple in Ohio, with as many as 25 or 30 mines sometimes occurring on one leaf. The larvae create elongated irregular blotch mines on the upper surfaces of leaves. The frass pattern appears to vary markedly, perhaps depending on the host species. Braun (1908) illustrated a mine with narrow, central, branching frass deposits. Eiseman (2019) reared an adult from an elongate, widening mine on Red Maple with the frass deposited in a central band. On two other occasions he raised adults from an elongate or branching mine on Southern Sugar Maple with some of the frass centrally deposited, and some along the margins as in C. aceriella. Larvae in North Carolina typically deposit the frass near the center of the mines, which is helpful in distinguishing this species from C. aceriella. The latter also uses maples, but deposits the frass along the outer margins of the mine.

Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.

Distribution in North Carolina

Distribution: Cameraria saccharella occurs from southern Ontario and Maine, southward and westward to Illinois, Ohio, and North Carolina. As of 2023, our limited records are from scattered localities in the Blue Ridge, Piedmont, and extreme eastern Coastal Plain.

Flight Comments: Populations appear to be bivoltine, with adults appearing shortly after the spring leaf-out and later in late-summer or early fall. Eiseman (2019) raised adults from mines that were collected in May, July, and August from North Carolina.

Habitats and Life History

Habitats: This species feeds on several species of maples. It likely occurs in urban landscapes, as well as hardwood and mixed hardwood-pine forests throughout the state.

Larval Host Plants: The documented host plants include Florida Maple (A. floridanum), Black Maple (A. nigrum), Red Maple (A. rubrum), Silver Maple (A. saccharinum), and Sugar Maple (A. saccharum) (Braun, 1908; Eiseman, 2019). In North Carolina, we have records for Sugar Maple, Florida Maple, and Red Maple. - View

Observation Methods: The adults appear to only rarely visit lights and are best obtained by rearing the adults.
