The Messalina Underwing (Catocala messalina) is a moth of the Noctuidae family. It is found from Virginia south to Florida and west to Texas and north to Kansas. The wingspan is 40-45 mm. Adults are on wing from May to August. There is probably one generation per year. The larvae feed on Quercus geminata, Quercus hemisphaerica and Quercus virginiana. A moth is an insect closely related to the butterfly, both being of the order Lepidoptera. Moths form the majority of this order; there are thought to be 150,000 to 250,000 different species of moth (about ten times the number of species of butterfly), with thousands of species yet to be described
