I photographed this moth in late July (July 19) in Vilas County Wisconsin (northern WI). It looks like a Big Poplar Moth, but it’s coloring is not quite right. Can you help identify it?

We verified the identity of your Modest Sphinx, Pachysphinx modesta, on Sphingidae of the Americas. It is also commonly called the Poplar Sphinx. A similar looking, related species in the same genus, Pachysphinx occidentalis, is commonly called the Big Poplar Sphinx, but it is a western species not reported in Wisconsin according to Sphingidae of the Americas.
