This appears to be a Streaked Orange moth (Nascia acutella), a species that the Peterson Field Guide to Moths of Northeastern North America by David Beadle and Seabrooke Leckie describes as “uncommon” with its host plant “presumably grasses and sedges”. It is an example of how little we know about some of these scarce, cryptic, often local or specialized moth species. Only by extensive searching and subsequent discovery can we begin to unravel the mysteries of their life histories.
