Clostera multnoma

Members of the genus Clostera are generally small to medium-sized notodontid moths with relatively broad wings and muted coloration. Specific diagnostic features for C. multnoma distinguishing it from congeners such as C. strigosa, C. albosigma, and C. brucei are not well documented in available literature. Accurate identification likely requires examination of genitalia or reference to original type specimens.

Documented from western Canada: Alberta, Manitoba, and Saskatchewan. Distribution records suggest a prairie and boreal forest zone occurrence pattern typical for many North American Notodontidae.

• Clostera bruceiTaxonomic synonymy; some authorities treat C. multnoma as a synonym of C. brucei, while others maintain species distinction. Morphological separation may be subtle or require genitalic examination.
• Clostera strigosaCongeneric species with overlapping North American distribution; both occur in similar western habitats and share general Clostera morphology.
• Clostera albosigmaWidespread congeneric species; may overlap in range and requires careful examination to distinguish from C. multnoma.
