Thirty-two Sphingidae species are listed in the USGS for California. Not all of the species are reported by USGS or anticipated in Orange County.
It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the moths you have encountered.
A WO" after the species name indicates that I have no confirmed reports of this species in Orange County, but I
(William Oehlke) expect that this moth may be present.
A USGS indicates the moth is reported on the USGS website (now BAMONA) and/or in Moths of Western
North America, #2. Distribution of Sphingidae of Western North America, revised, an excellent little booklet available through Paul Opler.
Please help me develop this list with improved, documented accuracy by sending sightings (species, date, location), preferably with an
image, via email to Bill Oehlke.
Many thanks to Jordan Craig who sent the following image of a male Pachysphinx occidentalis.

Eumorpha achemon, Laguna Canyon, Orange County, California,
Alida writes, "hello - found your site and am attaching a photo of a moth that was underneath a lot of vines and ferns that I was clearing just outside my front
door, in preparation for porch renovation."

I reply, "I suspect the vines were grape vines, a common foodplant of Eumorpha achemon."

Visit California Catocala: Underwing Moths
This species might be enountered in Orange County and in other
southern California counties.
The moth is a very strong flier and
is frequently encountered far north of its usual range.
This large bodied moth flies in tobacco fields and vegetable gardens
(potatoes, tomatoes) and wherever host plants are found.
WO, the Rustic Sphinx,
This species is not recorded in Orange County on USGS site.
I would not be surprised to get reports although Orange County would be the northern
limit of its range in California. Look for three large yellow spots
on each side of the abdomen.

Manduca sexta USGS/Joyce, the Carolina Sphinx
This species is recorded in Orange County.
If you grow tomatoes, you have probably encountered it.
Larvae get very large and can strip a tomato plant.
Sphinx chersis WO, Northern Ash
Sphinx or Great Ash Sphinx.
The upperside of the forewing is soft dark gray to blue-gray with a series of black dashes,
one of which reaches the wing tip.
WO, the Elegant Sphinx.
Sphinx perelegans adults fly in montane woodlands and mixed
chaparral-type vegetation as a single brood
in the north, with adults mainly on the wing in June and July.
It flies from dusk until after midnight. maybe
This species is not reported in Orange County.
Adults fly as a single brood in the desert and in pinyon-juniper
woodland from May to August. maybe
Pachysphinx occidentalis male, Tustin, May 4, 2010, courtesy of Jordan Craig.
This one is quite similar to Pachysphinx modesta, with modesta
being smaller and darker.
Moths would be on the wing from June-August.
Smerinthus cerisyi USGS, the Cerisyi's
Sphinx or One-eyed Sphinx,
Larvae feed on poplars and willows.
Flight would be from late May-July as a single brood.
Smerinthus saliceti, San Clemente, September 4, 2016, Monika Burke
WO/MB, the Salicet
Sphinx, flies in valleys and along streamsides from Mexico City north
to west Texas, southern Arizona, and extreme southern California.
Larvae feed on poplars and willows.
Flight would be from late April-September, probably as a double brood.
The body is dark brown with a wide white
band across the abdomen. Wings are dark brown. The forewing has a
black cell spot and 3 white spots near the pale brown marginal
area. unlikely stray
This species is reddish, has falcate wings
and flies after midnight.
It is very questionable for
Orange County, but may stray into
that area. unlikely stray
This species is more likely to occur as an occasional stray rather
than as a breeding resident.
As a migrant stray it would be seen
later in the season, July-August. unlikely stray
The abdomen has very distinct gray and black bands.
Adults nectar at dusk so you may see them in the garden at that
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.
Hemaris thetis USGS, the Thetis Clearwing or Bee Hawk Moth,
The moth flies along forest edges and in meadows, gardens and
brushy fields. Day-flying adults nectar at lantana, dwarf bush honeysuckle,
snowberry, orange hawkweed, thistles, lilac, Canada violet, etc.
Eumorpha achemon, Laguna Canyon, July 8, 2014, courtesy of Alida Cervera.
Eumorpha achemon WO/AC,
the Achemon Sphinx.
This moth is now reported for Orange County, and should be fairly
common. Fight would be from June to August. Larvae feed on grape foliage.
This moth is a very strong flier and is often reported far north of
its normal range.
It would be a rare stray to Orange County if it is at all present. unlikely stray
the Phaeton Primrose Sphinx, WO.
Adults nectar at flowers during the warm parts of the day.
Euproserpinus phaeton adults fly swiftly and close to the ground over
dry washes and flat areas in deserts as a single brood from
Hyles lineata, San Juan
Capistrano, May 18, 2008, 9 pm., courtesy of Andrea Bink.
USGS, the White-lined Sphinx
Adults usually fly at dusk, during the night, at dawn, and during the
day. Moths nectar at salvia and other flowers and oviposit on
Epilobium cana (California fuchsia) and Hooker's Evening
Primrose, and others.
Hyles lineata, Huntington Beach, April 7, 2012, courtesy of John Prince
Adults fly in the afternoon from April-June in oak woodland and
pine-oak woodland in foothills, nectaring from chia, heartleaf
milkweed, golden currant, bluedicks, fairyfans, vetches,
thistles, hedgenettles, etc.

wing in the early evening. It comes to lights at night. maybe
Enjoy some of nature's wonderments, giant silk moth cocoons.
These cocoons are for sale winter and fall. Beautiful Saturniidae moths will emerge the following spring and summer.
