Army cutworm (Euxoa auxiliaris) moths summering in Great Basin National Park

Army cutworm (Euxoa auxiliaris) moths summering in Great Basin National Park. Research Permit and Reporting System

Native army cutworms (Euxoa auxiliaris) consume cheatgrass (Bromus tectorum) to produce "die-offs." Understanding Euxoa auxiliaris outbreaks and migrations will let us predict cheatgrass die-offs so we can reseed these areas. In August, 2020, I visited 11 sites in GRBA where army cutworm moths had been collected. I searched excellent moth habitat along streams and at high elevations, and surprising habitats at low elevations in an old orchard and open woodlands. But I didn't find any moths.
