Spinose Flower Moth
Schinia spinosae (Guenée, 1852)
Insects

Identifying Characteristics [-]
The spinose flower moth is various shades of brown with large pale patches. The wingspan is approximately 23-24 mm.

Best Life Stage for Proper Identification [-]
The adult stage is the best life stage for identification.

Behavior [-]
Eggs of moths in this genus develop quickly, and the larval stage is usually three to four weeks or less. Pupation occurs under the ground (Wagner et al. 2008).

Diet [-]
Most moths in this genus have a specialized diet. For many Flower Moths, the host plant on which moths lay eggs and larvae feed is the only plant on which moths nectar. The food source of the spinose flower moth is not known, however, it is known to use plants in the genus Polygonella as host plants. In particular, across much of its northern range, it seems to use coastal jointweed (Polygonella articulata) as a host plant (Wagner et al. 2008).
