A couple days ago I found three different species of sphinx moth in the lobby of a local hotel. This one, the smallest, was probably the most beautiful. I can imagine that it is incredibly camouflaged when sitting on a tree trunk. In a hotel lobby, less so. This species, Enyo lugubris, is apparently known as the Mournful Sphinx, and only the males have the strange fan on the end of their abdomen.
I just spotted this moth, which I thought was a hummingbird, in Mobile, AL
