I found this sphinx moth on 6/16/12 in Door county, WI. Is it a Clemens and if so, any insight on them?

Wow, this sighting has us excited. You are correct, it is the Clemens or Canadian Sphinx, Sphinx luscitiosa, and according to the Sphingidae of the Americas website, it is rare. From that site, we have gleaned that males take nectar during the day and only females are attracted to lights at night. It is also interesting that they are reported to feed on the fluids of rotting fish. The food plants for the caterpillars are listed as “willow (Salix), poplar (Populus), birch (Betula), apple (Malus), ash (Fraxinus), waxmyrtle (Morella), and northern bayberry.” We will copy Bill Oehlke on this reply in the event he can add any information and he also may request permission to reproduce your photo on his excellent website. BugGuide also provides this information: “Global Rank: G3 – Very rare or local throughout its range, or found locally in a restricted range (21 to 100 occurrences). Threatened throughout its range.”
