I saw this yesterday, and I’m pretty sure it’s a sphinx moth, but I’m a casual bug gal, so I don’t know which type. Do you?
Gardiner, Maine, sitting on the side of a building along Route 24, which parallels the Kennebec River.
It was late morning, probably 10:30 or so, on a sunny day, temps in the low 70’s, June 15, 2013. I’ve got a request out to my invert guy in Maine, but I thought you might like to see the photos too.
Just found your site, it looks great!
This is a recently eclosed Sphinx Moth and its wings have not fully expanded. Because the wings are not ready for flight, we are uncertain of the exact identity, but we believe this is a species related to the Canadian Sphinx known as the Poecila Sphinx, Sphinx peocila. According to the Sphingidae of the Americas website: “The outer wing fringes are checkered black and white on the forewing, and are almost pure white (lightly checked with grey) on the hindwing. The forewing is dark gray with diffuse black and gray wavy lines with a series of black dashes ending at the wing tip, and a white cell spot. The white cell spot readily distinguishes poecila from canadensis. The hindwing is brownish gray with a wide black border and a black median line.” Your individual has a prominent white cell spot. We wish the underwings were visible. We will contact Bill Oehlke for confirmation on this Sphinx Moth. Let us know what your invert guy has to say.

Ceratomia amyntor that has not inflated its wings. They are reported
