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

This page is inspired by and dedicated to Don Muse of the Sierra foothills in Reno, Nevada (Washoe County).

Don writes (April 9, 2007):

"The moth was obtaining nectar from the little blue ground cover flower (probably Gentianopsis holopetala = Sierra gentian). This was taken in about 2003 on an eastern Sierra foothill during a lovely spring season."

Eighteen Sphingidae species are listed for Nevada on the U.S.G.S. website. Not all of the species are reported or anticipated in Washoe County (Five are reported on U.S.G.S.: Big poplar sphinx (Pachysphinx occidentalis), One-eyed sphinx (Smerinthus cerisyi), Small-eyed sphinx (Paonias myops), White-lined sphinx (Hyles lineata) and Clark's sphinx (Proserpinus clarkiae)).

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:

Agrius cingulata WO

This species has not been reported in Washoe County, but may be there as a very rare stray.

The moth is a very strong flier and is frequently encountered far north of its usual range.

Manduca quinquemaculata WO, the Five-spotted Hawkmoth

This large bodied moth flies in tobacco fields and vegetable gardens (potatoes, tomatoes) and wherever host plants are found.

Manduca sexta WO, the Carolina Sphinx

This species is not recorded in Washoe County. however, if you grow tomatoes, you may have encountered it.

Larvae get very large and can strip a tomato plant.

Sphinx chersis WO, the 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 reaching the wing tip. Note grey thorax with narrow black lines.

Sphinx drupiferarum WO, the Wild Cherry Sphinx

Forewings, long and slender, are held close to the body when the moth is at rest. I only see them occasionally on P.E.I. despite visiting lights frequently. Hence they may be present, but seldom seen.

Sphinx perelegans 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. Note dark thorax.

Sphinx vashti WO, the Snowberry Sphinx

The upperside of the forewing has a narrow black subterminal line bordered by a white inverted V-shaped line on the outside, and a black line running inwards from the apex of the wing.
It is most often found in montane woodlands and along streamcourses.

Smerinthini Tribe:

Pachysphinx occidentalis USGS, the Big Poplar Sphinx

This one is quite similar to Pachysphinx modesta, with modesta being smaller and darker.

Moths should 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.

Paonias myops USGS, the Small-eyed Sphinx

This small species is present in Washoe County. This species ranges across North America.

The hindwings have a small blue eyespot ringed with black on a yellow background.

Hemaris diffinis WO, the Snowberry Clearwing or Bumblebee 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.

Philampelini Tribe:

Eumorpha achemon WO, the Achemon Sphinx

Adults nectar from flowers of Japanese honeysuckle (Lonicera japonica), petunia (Petunia hybrida), mock orange (Philadelphus coronarius), and phlox (Phlox). Fight would be from June to August. Larvae feed on grape foliage.

Macroglossini Tribe:

Euproserpinus phaeton, 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 February-April.

Hyles lineata USGS/DM, the White-lined Sphinx

Adults usually fly at dusk, during the night, at dawn, and during the day. Moths nectar at a number of different flowers and oviposit on Epilobium cana (California fuchsia) and Hooker's Evening Primrose.

Proserpinus clarkiae USGS, Clark's Sphinx,

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.
