Klickitat County

Sphingidae

Seventeen Sphingidae species are listed for Washington. Not all of the species are reported or anticipated in Klickitat. 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 your county, but I (William Oehlke) expect that this moth is present. A "USGS" indicates the moth is reported in USGS 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 likely present (reported in Yakima) and larvae feed on tomatoes and go by the common name of "Tomato Hornworms".

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 of which reaches the wing tip.

Sphinx drupiferarum WO, the Wild Cherry Sphinx

Although not reported from Klickitat (reported in Yakima), 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. Reported in Yakima.

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 occidentalis USGS, the Big Poplar Sphinx

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

If you've got willows or poplars nearby, then you probably have occidentalis in your immediate area.

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.

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 diffinis WO, the Snowberry Clearwing or Bumblebee Moth

Although not officially reported from Klickitat, this day flying moth is widely distributed in Washington (Yakima +).
I suspect I will get reports from Klickitat County.

Hemaris senta USGS Rocky Mountain clearwing

This report from USGS may be in error as this moth (a day flier in mountain meadows) is easily confused with Hemaris diffinis.

Klickitat is the only county reported in WA. or OR.

Macroglossini tribe

Hyles gallii WO, the Bedstraw Hawk Moth or Gallium Sphinx

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

Hyles lineata DM, the White-lined Sphinx

Dave McNeese reports this species. 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.

Hyles lineata: Dave McNeese DM, mile post 119 on Hwy. 14, Goldendale, 3:30 p.m., May 22

Proserpinus clarkiae LG/WO, Clark's Sphinx

Now officially reported from Klickitat County, this day flier, April-June, prefers oak woodland and pine-oak woodland in foothills. Moths nectar at a variety of flowers in the afternoon.

Proserpinus clarkiae: May 11, 1997, Larry Gooding LG reports a sighting (moth nectaring at flowers) at mid-day, east of Lyle: leave Hwy 14 at milepost 77 and hike on "Cherry Orchard Trail", an unofficial trail. Oak scrub and grassland.

Proserpinus flavofasciata WO, the Yellow-banded Day Sphinx
This species is not officially reported from Klickitat, but it is found to the north, east and south and may be present. It nectars during the day in meadows near coniferous forests.
