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 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."
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
Gila County (sixteen 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.
Sphinginae subfamily
Sphingini tribe:
 |
This moth is a very strong flier, and make its way to
southern Arizona and southern California.
It is not confirmed for Gila County, but might occur as a rare stray.
|
 |
The upperside of the forewing is gray to yellowish gray to brown.
The reddish brown patch
just outside the cell and above the dashes is the most distinguishing
character.
|
 |
This species is confirmed in Gila County, and
has been seen in nearby counties.
I suspect if you grow tomatoes, you might encounter it.
|
 |
This species is not officially recorded in Gila County,
but it has been taken in other nearby counties. Look for three
large yellow spots on each side of the abdomen.
rare, if present
|
 |
This species has been recorded in Gila County by Evan Rand.
If you grow tomatoes, you may have encountered it.
Larvae get very large and can strip a tomato plant.
|
 |
The upperside of the forewing is pale silver-gray with a series of
black dashes, a white patch at the tip, and a white stripe along the
outer margin. The upperside of the hindwing is black with blurry
white bands.
|
 |
Sphinx chersis
USGS/ER,
the Northern Ash Sphinx or Great Ash Sphinx
This species is reported in Pima. Larval hosts are ash,
lilac, privet, cherry, and quaking aspen.
|
 |
Sphinx dollii
USGS/ER--common,
the Doll's sphinx
Sphinx dollii (Wing span: 1 3/4 - 2 1/2 inches (4.5 - 6.3 cm)),
flies in arid brushlands and desert foothills from Nevada and
southern California east through Utah,
Arizona, Colorado, and New Mexico to Oklahoma and Texas.
|
Smerinthini Tribe:
 |
This one is quite similar to Pachysphinx modesta, with modesta
being smaller and darker.
Moths should be on the wing from June-August.
|
 |
The outer margin of the forewing is quite wavy. There
is a dark cell spot and a dark oblique line mid wing from the
costa almost to the inner margin. Basic ground colour is
pinkish brown. Flight would be June-July. probably rare |
 |
Paonias myops
USGS/ER--rare,
the Small-eyed Sphinx Named for the small eye-spot in the
hindwing, this moth has a wide
distribution but is probably quite rare in Gila County.
|
 |
Smerinthus cerisyi
USGS/ER--uncommon, the Cerisyi's
Sphinx or One-eyed Sphinx, Larvae feed on poplars and willows.
Flight would be from late May-July-early August as a single brood.
|
Macroglossinae subfamily
Dilophonotini tribe:
 |
The upperside of the abdomen is gray, without black bands, and
the underside does not have black spots. The upperside of the
forewing is dark brown, and may have pale yellow-brown patches
along the inner edge. rare stray
|
 |
This species is reported in Gila County and in other southern
Arizona counties. Males and females differ.rare stray
|
 |
During the night adults nectar at flowers, including bouncing bet
(Saponaria officinalis) and Asystasia gangetica beginning at dusk.
July and August are flight times in the southern states. rare stray
|
 |
Hemaris diffinis
USGS, the
Snowberry Clearwing or Bumblebee Moth
This moth is widespread and has been officially recorded in
Gila County.
|
Philampelini tribe:
 |
This moth is officially reported for Gila County.
Eumorpha achemon larvae feed upon Grape (Vitis),
Virginia Creeper (Parthenocissus quinquefolia)
and other vines and ivies (Ampelopsis).
probably rare
|
 |
The Gaudy Sphinx flies in America, and although primarily a
tropical species, it has been taken as far north as
Saskatchewan as a stray. Forewings are a vibrant grey-green.
rare stray
|
 |
The upperside of wings is deep red-brown with pale brown bands. Each
hindwing has pink along the costal margin and a triangular white spot
on the outer part of the inner margin. confirmed by Evan Rand

Macroglossini tribe:
 |
Hyles lineata
USGS/ER-very common,
the White-lined Sphinx
Larvae can be quite varied.
|
|
|
Evan Rand writes, "Hyles lineata is very
common and widespread throughout the state. For example, I had
about six come to my lights in March in Gardner Canyon
(Pima Co.) in only an hour of lighting. I had several dozen
come to MV lights by Pena Blanca Lake (Santa Cruz Co.) last
year. A few years ago I saw thousands of larva crossing the
desert west of Tucson in August (Pima Co.). I've seen hundreds
of adults come to large lights in Scottsdale (Maricopa Co.) in
late March/early April. In Sycamore Creek (extreme NE Maricopa
Co.) in August of 2005 I saw hundreds flying just before dark.
I usually encounter them in moderate numbers (maybe 5-6 per
night) in Gila Co. in late July and early August coming to gas
station lights in Payson, Star Valley, Pine and Kohl's Ranch.
I've seen them in numbers during the afternoon taking nectar
from petunias just north of Page in S. Utah in late May. To
summarize, it's by far the most common sphingid in the state,
and I bet it's found in every county (although I can't confirm
that)."
On August 8, 2007, Evan writes, "I just started with central Arizona
where Hyles lineata is having an excellent year. There are
about 10 times more than average. I've also gotten
Manduca sexta, Sphinx dollii, Pachysphinx occidentalis, and
Smerinthus ceryisi (which is pretty typical) to come to
lights. Also, there have been a few Sphingicampa hubbardi.
However the find so far has been a Gila county record
Manduca florestan (perfect specimen as well)."
