Grote’s Sallow
Copivaleria grotei (Morrison, 1874) P-no. 931557, fam. Noctuidae
Host plant: green ash (Fraxinus pennsylvanica)
Dates found: 2 May, 2026
Locations found: Tyson Research Center, St. Louis County, MO
Notes: Copivaleria grotei is classified within a monotypic genus, meaning it is the sole member found in the genus Copivaleria. But it is not alone among many lepidopterans that specialize on ash trees or use ash trees as one of their preferred hosts. These species are at risk in Missouri due to the destruction of millions of ash trees by the invasive emerald ash borer (Agrilus planipennis).
