Found today on July 17, 09. It mostly has gray coloring matching the local oak and pine trees. Its hind wings have brilliant burgundy markings. Would love to know what it is and any info you can give me. Thanks!!!

Dear Miss Bolding,
Your moth is a Western Poplar Sphinx, Pachysphinx occidentalis. It is found in western North America. There is a light and a dark form, and your moth is a lovely example of the light form.

I live in long Island, New York. Today my son yells “mom come and see this.” On the front door screen was a huge bug, light brown, with dark eyes, the wings look like it was wearing a cape. Before i could get my phone or camera my son tapped the screen and the bug flew away. I never saw an insect like this therefore I went online to look at photographs of insects, from the photos on this site we concluded that this huge bug was a WESTERN POPLAR SPHINX, and we saw it in New York. Awesome!
