Wing span: 80mm
Flight time: July - September
Description. FW pale gray, with thin blackish lines and light brown shadings. Female more mottled than male, with slight basal dash (usually completely absent in male). HW yellow-orange with black bands; fringe broad and often mostly yellow-orange (males); basal hairs only slightly darker than ground. Underside light yellow-orange and black; with very wide, light outer border and fringe on HW. 75-90 mm. H 33: 15. B & Mc 6: 15, 16.
Similar species. Often confused with neogama, but usually paler and less contrastingly marked on FW; HW has narrower black bands and less contrasting basal hairs, giving a much paler overall appearance. Male neogama generally have at least a trace of a basal dash.
The following distinction between these two species was discovered by Douglas C. Ferguson, and seems entirely reliable. It is best seen under magnification.
C. subnata -- hind tibia almost cylindrical in cross-section, densely and uniformly covered with spines on outer (ventral) surface.
C. neogama -- hind tibia strongly compressed in cross-section, sparsely and sporadically spined on outer (ventral) surface.
Range. Southern Canada (Ontario, Nova Scotia -- one record) to North Carolina and west throughout area.
Status. Generally quite rare, but apparently exhibits long-term fluctuations in abundance (Forbes, 1954).
Larval foodplants. Butternut (Juglans cinerea) (JGF), and possibly Black Walnut (J. nigra) and hickories (Carya).
Notes. Moth rests head-down on tree trunks, often hickories and walnuts (MCN).
