Ragweed Flower Moth
Schinia rivulosa (Guenée, 1852), fam. Noctuidae, P-no. 932091
Host plants: Hosts solely on ragweed (Ambrosia spp.).
Date found(s): September 4, 2026
Location(s) found: Ste. Genevieve County, MO
Notes: For those with a sensitivity to ragweed, like me, the ragweed flower moth should be a favorite. This abundant species feeds on flower buds, blooms and seeds of Ambrosia, acting as a significant natural control for these highly allergenic plants.
