Northern Ash Sphinx, we believe
Northern Ash Sphinx

Dear Lesley,
Though it resembles the Australian Wood Moths, this is actually a Sphinx Moth or Hawkmoth in the family Sphingidae.  We believe it is the Northern Ash Sphinx or Great Ash Sphinx,
Sphinx chersis, which is profiled on the Sphingidae of the Americas site, but there are several other similar looking members of the genus Sphinx pictured on the website’s California page, and we would not rule them out.  We will contact Bill Oehlke to see if we can get a definitive identification from him.

Bill Oehlke concurs
Sphinx chersis, possibly an aberration or less commonly seen form. Lines on thorax and wings seem especially thick, checkered fringes are missing and some other features are reduced in their contrast to rest of wing. I had to look at it carefully. It probably has not flown yet.
