The hummingbird clearwing moth, Hemaris thysbe, has a wingspan of about two inches. Click to enlarge.
The moth in the picture is hovering in the air while sipping nectar from a wild bergamot blossom. I spied it in Brooklyn Bridge Park this week. Initially, it is easy to mistake this fat furry reddish moth for a tiny hummingbird. Then it comes into focus and you see the antennae, the proboscis, and all the legs. In all the photos I took of this moth, it rested its front pair of legs on the blossom while drinking.
