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".
