Found this beauty outside the butterfly garden I worked at this summer. Had large transparent patches on its wings.

Though there are several similar looking, closely related species in your area, we agree that this is most likely a Hummingbird Clearwing, Hemaris thysbe, and you can read more about it on the Sphingidae of the Americas site.
