This photo was taken by a Bulwark Pest Control technician working in Tulsa, OK. Moths are among the largest insects in the world. Some moths reach a wing span of 12 inches. They are quite beautiful in flight. Because of their size these large moths could almost be mistaken for a bat, except that they are much slower. Large moths beat their wings to a very melancholy beat, barely sustaining flight. This Tulsa moth isn’t as big as it may appear in the photo.
