Noctua comes is a fairly large (FW length 19-21mm) Noctuid that is native to Eurasia and arrived in British Columbia in the early 80s and has since spread through the western parts of BC, Washington, and Oregon. It is a sturdy looking moth with a broad forewing that is tan to dark brown, with orbicular and reniform spots that are at least slightly darker than the surrounding scales, and a yellow-orange hindwing with a black margin and black discal spot. It is only likely to be confused with the much larger Noctua pronuba, which has longer, narrower forewings, 2 black (possibly fused) dots near the apex of the forewing, and lacks the discal spot in the hindwing.
The larvae feed on a variety of plants, including those in the Polygonaceae, Scrophulariaceae, Asteraceae, Plantaginaceae, and Rosaceae families. Adults are in flight from June to October.
