Backyard Summertime Nature in New Jersey.
Hummingbird Clearwing Moth on a Thistle Bloom. Image taken with a Nikon D4 camera and 300 mm f/4 VR lens (ISO 100, 300 mm, f/8, 1/250 sec). Raw image processed with Capture One Pro, Focus Magic, and Photoshop CC.
This one does appear to be a Hummingbird Clearwing Moth (Hemaris thysbe) based on 1) the lack of any banding on the lateral side of the thorax; 2) thysbe always has yellowish or pale colored legs.
