Explanation of Names
NUBILOFASCIATA: from the Latin "nubilus" (cloudy), from "nubes" (a cloud) + "fascia" (a band); refers to the obscure or indefinite appearance of the bands on the forewing
Size
wingspan 27-31 mm (based on eight specimens)
Identification
Adult: FW extremely variable in color and pattern; "typical" specimens have four gray bands alternating with four light gold or greenish bands; PM line forms a smooth concave arc for most of its length, then angles inward near costa (a distinguishing feature); some individuals have a pale median area and dark patches in AM and subterminal areas, others have the reverse pattern - dark median patch and pale AM and subterminal areas; some individuals are uniformly pale except for dark AM and PM lines (see four examples of pinned adults); apical dash composed of 2-4 black spots arranged in line; dark patches along costa interspersed by pale whitish lines or patches. HW pale cream to grayish-brown with three indistinct bands
