Spinose Flower Moth

The spinose flower moth (Schinia spinosae) is a small noctuid native to North America. It has a wingspan of approximately 22–24 mm. The is a herbivore whose larvae feed on Polygonella species, with Polygonella articulata documented as a primary in northern portions of its range. are presumably and attracted to light, consistent with other members of the Schinia.

Identification

The small size (22–24 mm wingspan) and association with Polygonella plants may aid identification. Within the Schinia, which contains over 120 North American , precise identification to species level typically requires examination of genitalia or reference to regional identification guides. No distinguishing external features are explicitly documented for this species in available sources.
