They're Baaaack . . . They're Baaaack . . . Unusually early cutworm larvae are being found in some sections of Montana, and Russian wheat aphids have been detected too, say Montana State University - Bozeman entomologists.
Cutworms are a frequent problem in Montana.
Their unusual early development this spring is due to our warm dry winter, which is exactly what the Russian wheat aphid prefers. Russian wheat aphids usually migrate into Montana, but they have been found this year in Cascade and Teton Counties and in the Molt - Rapleje area. Their presence this early in the year indicates they survived the winter, says Greg Johnson, MSU Entomology Department head. That hasn't happened since 1992. Cutworms aren't any fun either.
