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