The wingspan of this moth was about 4.5 cm and it sounded rather heavy while bouncing off my porch light. There are five Mocis species in North America.

The second Mocis species that I found in our yard. The wingspan is about 1.5". The larvae are called "Striped Grass Looper" and feed on grasses, corn, beans and turnip. The second link is for a dissertation titled "Behavioral biology of the striped grass looper, Mocis latipes (Guenée), in north-central Florida".
