Schinia spinosae
Guenée, 1852
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.

- Polygonella - larval -level association
Life Cycle
Complete with , larva, pupa, and stages. Specific details of voltinism, stage, and developmental timing are not documented.
Behavior

Ecological Role
As a herbivore on Polygonella, larvae contribute to herbivory pressure on this plant . may serve as when visiting flowers for nectar, though this has not been documented. The functions as prey for various and , typical of small .
Human Relevance
No significant documented interactions with humans. The is of interest to lepidopterists and enthusiasts, particularly during National Moth Week events and similar citizen science initiatives.
