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

This page is inspired by and dedicated to Evan Rand of Phoenix, Arizona (Maricopa County).

Evan writes, "I do frequent light-trapping in the summer. I do set up traps frequently in neighboring Gila County and in Maricopa County. I have personally collected two Eumorpha typhon specimens (both perfect) in Gila County."

Evan sent the following summary, which probably also applies to Navajo County, for Gila and nearby counties:

"Paonias myops - Edge of Maricopa Co./Gila Co. 8/05 (rare only seen 1)
Pachysphinx occidentalis - Uncommon Both Maricopa Co. and Gila Co. From April to August
Eumorpha achemon - Maricopa Co. (rare only 1 in April)
Eumorpha typhon - Gila Co. (rare only 2, late July, early August)
Manduca sexta - Uncommon in Maricopa Co. (Mostly seen in late September, early October) Uncommon in Gila Co. (Late July/August), Common in Santa Cruz Co. (Late July/August)
Manduca rustica - Rare in Maricopa Co. (late September), uncommon in Santa Cruz Co.
Manduca muscosa - uncommon in Santa Cruz Co. (late July)
Agrius cingulata- Rare in Maricopa Co. (late September)
Smerinthus cerisyi - Uncommon in Maricopa and Gila Co. (late July/early August)
Sphinx dollii - Common in Gila Co. (late July/early August)
Sphinx chersis - Uncommon in Gila Co. (late July/early August)
Xylophanes falco - Uncommon in Santa Cruz Co. (late July/early August)
Hyles lineata - Very common Maricopa, Yavapai, Gila, Pima, Santa Cruz Cos. (March to October). This species is extremely common almost everywhere, I've seen hundreds of individuals at a single light before, and thousands of larva crawling across the desert. It's hard to light trap anywhere between March and October and not get at least one H. lineata."

Evan Rand writes, May 2010: "I've encountered enough fresh Manduca florestan in Gila and Navajo Cos. in the past two years that I'm pretty sure they're breeding there, which is considerably farther north than most other information indicates."

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 Navajo County (nine are reported on U.S.G.S.). 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.

Agrius cingulata, WO??, Pink-spotted Hawkmoth

This moth is a very strong flier, and make its way to southern Arizona and southern California.
