Hypocoena rufostrigata

The combination of moderate size (26–30 mm wingspan), brown streaked forewings, and geographic range along the Atlantic coast and western North America helps distinguish this species. It may be confused with other Hypocoena species, though specific diagnostic characters require examination of genitalia or detailed wing pattern analysis.

Adults have a wingspan of 26–30 mm. The species exhibits a brownish coloration with streaked patterning on the forewings, consistent with its common name.

Found in coastal and inland habitats across its broad North American range. Specific microhabitat preferences are not well documented.

Atlantic coast of North America, extending north to Northwest Territories and Alaska, and south in the western portion of its range to California and Utah. Canadian provincial records include Alberta, Manitoba, and Saskatchewan.

Adults are on wing from June to September. There is one generation per year, with the possibility of a partial second brood in some regions.

Univoltine with one generation per year; partial second brood may occur. Larval stages and host plants are not documented in available sources.

Adults are nocturnal, as is typical for Noctuidae. Specific behavioral observations beyond flight period are not documented.
