Dear Harley,
This gorgeous moth is an Underwing Moth in the genus
Catocala, but we are uncertain of the species.  This is a large genus, and according to bugGuide:  “Lafontaine & Schmidt (2010) listed 101 species of the genus Catocala in America north of Mexico. Powell & Opler (2009) reported 110 species in all of North America.”  The common name Underwing is derived from the contrasting and often brightly colored underwings that are generally hidden when the moth is resting.  They flash when the moth is in flight, causing a predator to search for a colorful prey, but while the moth is resting camouflaged on a tree trunk, it eludes its hunter and avoids getting eaten.  You didn’t indicate if this sighting was during the day or at night.  Underwings are often attracted to lights at night.
