Lincoln County, Washington
Sphingidae

Seventeen Sphingidae species are listed for Washington. Not all of the species are reported or anticipated in Lincoln 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 Lincoln County, but I (William Oehlke) expect that this moth is present. A USGS indicates the moth is reported on the USGS website 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.

Sphinginae subfamily

Sphingini tribe:

Manduca quinquemaculatus WO, the Five-spotted Hawkmoth

This species is probably present (unreported) and larvae feed on tomatoes and go by the common name of "Tomato Hornworms".

Sphinx drupiferarum WO, the Wild Cherry Sphinx

Although not reported from Lincoln, I suspect it is present. I only see them occasionally on P.E.I. despite visiting lights frequently.

Sphinx perelegans WO, the Elegant Sphinx

The upperside of the forewing is dark grey to black with a paler costa and pale area from the base to the wing's centre.
Prefered habitats include montane woodlands and mixed chaparral-type vegetation.

Sphinx vashti USGS, 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 modesta WO, the Modest Sphinx or Poplar Sphinx,

This large poplar/willow feeder is probably quite common in Lincoln. They are a heavy bodied species.

Pachysphinx occidentalis WO, the Big Poplar Sphinx

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

There may be naturally occuring hybrids in Lincoln.

Paonias excaecata WO, the Blinded Sphinx

The grey-blue eyespot of the hindwing gives this species its name. Larvae feed on birches, willows, cherries and oaks.

The outer edge of the forewings is quite scalloped.

Paonias myops WO, the Small-eyed Sphinx

This small species is probably widespread and common. This species ranges across North America.

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

Smerinthus opthalmica MPNw

Larvae feed on poplars, aspen and willows. Note different shape of double arced forewing pm line compared to the straighter pm line of cerisyi, which it replaces in WA. S. ophthalmica has smoother scalloping of the fw outer margin.

Macroglossinae subfamily


Dilophonotini tribe

Hemaris thetis USGS, the Thetis Clearwing

Hemaris thetis is a very variable species, but almost always the abdomen sports contrasting black and yellow hairs, the ventral surface being quite black. The legs also tend to be quite dark and there is a black mask running across the eye and along the sides of the thorax.

Macroglossini tribe

Arctonotus lucidus PE, the Pacific Green Sphinx Moth or Bear Sphinx

Found to the north, east and west, this species is probably present.
It tends to be an early spring flier, on the wing in the early evening. It comes to lights at night.

Hyles gallii WO, the Bedstraw Hawk Moth or Gallium Sphinx

This species is not officially reported from Lincoln County, but if you have Gallium or Epilobium, you probably have populations of this species.

Hyles lineata WO, the White-lined Sphinx

This species is very widespread. It can be seen flying during the day, into the evening and also at night.
The highly variable larvae are often found in people's gardens.

Proserpinus clarkiae WO, Clark's Sphinx

Although not officially reported from Lincoln County, this day flier, April-June, prefering oak woodland and pine-oak woodland in foothills, is probably present. Moths nectar at a variety of flowers in the afternoon.

Proserpinus flavofasciata WO, the Yellow-banded Day Sphinx

This day flier is not officially reported from Lincoln, but it has been found to the north, east south and west in meadows near coniferous forests.

Here are sighting records and general information for Sphingidae in Lincoln County in northeastern Washington.
