Comments, suggestions and/or additional information/sightings are welcomed by Bill.

This page is inspired by and dedicated to Bill Wohlenhaus of Mohave County in northwestern Arizona. Bill sent me the images Pachsyphinx occidentalis, top and bottom of this page.

Bill writes (September 26, 2008):

"This moth was found in Wikieup, Arizona (Mohave County) on the night of September 24. Is this P. Occidentalis or Modesta?

"Feel free to use the images if you'd like.."

Fifty-three Sphingidae species are listed for Arizona on the U.S.G.S. website. Not all of the species are reported or anticipated in Mohave County (seven are reported on U.S.G.S. as of September 27, 2008). It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the moths you are likely to encounter.

A "WO" after the species name indicates that I (William Oehlke) expect that this moth is present or might be present, although unreported. A "USGS" indicates the moth is confirmed on USGS site.

Please help me develop this list with improved, documented accuracy by sending sightings (species, date, location), preferably with an electronic image, via email to Bill Oehlke.
