Grote, 1881

Schinia luxa is a noctuid native to southwestern North America. The exhibits variable coloration, ranging from plain white or light gray to individuals with dark gray spotting. are active from August to September, with a wingspan of 26–31 mm. The larvae are feeders on Mentzelia species.

Identification

Distinguished from other Schinia by its predominantly pale, unmarked or lightly spotted appearance. Many Schinia species exhibit bold, contrasting color patterns associated with specific flowers; S. luxa lacks such strong patterning. The combination of pale gray-white ground color, variable dark spotting, and southwestern distribution helps separate it from similar pale noctuids. Examination of genitalia may be required for definitive identification where range overlaps with related species.
