Clallam County

This page is dedicated to Betty Bates who sent me the image of Smerinthus ophthalmica at top of this page.

Betty writes, "My name is Betty Bates, and I live in Port Angeles, WA. (actually halfway between Port Angeles and Sequim along the Strait of Juan de Fuca). On Wednesday, July 14th, I was sweeping out my garage and right outside my garage door was this moth (see attached picture). I was fascinated by the colorful "face" that this moth had on its wings. My sister-in-law checked out her Northwest Guide book to plants and bugs and told me about the moth called, "Cerisy's Sphinx".

"I did a Google search and found your website. I was wondering if this moth was indeed Cerisy's Sphinx or the Twin Spotted Sphinx. This is the first time I have seen a moth like this in the 17 years that I have lived here. I have seen many other types of moths around here but never one with such a colorful and amazing design.

"Any info would be very much appreciated."

I replied, "Your sister-in-law is correct (now (2013) revised to S. ophthalmica). It is Smerinthus ophthalmica. They are very close in appearance to the Smerinthus cerisyi. One subtle, but consistent, difference is that in ophthalmica the forewing post median line is formed by the union of two convex arcs while in cerisyi the broader pm line/band is a relative straight series of line segments/bars. Also not the smoother scalloping of the forewing outer margin in ophthalmica.

"I would like permission to post image, credited to you, to a webpage??

"In which Washington County do you reside?"

It is also likely that Smerinthus jamaicensis does not fly in Washington, although it is reported in southern British Columbia, Canada.

Those specimens from Washington previously listed as S. cerisyi are probably all S. ophthalmica.

Seventeen Sphingidae species are listed for Washington. Not all of the species are reported or anticipated in Clallam County in northern Washington. It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the moths you have encountered.

The Cascades seem to be a barrier to some of the more eastern species.

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.

A "WO" after the species name indicates that I have no confirmed reports of this species in Clallam County, but I (William Oehlke) expect that this moth is or might be present.

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 possibly present (unreported) and larvae feed on tomatoes and go by the common name of "Tomato Hornworms". Sphinx drupiferarum WO, the Wild Cherry Sphinx There is a broad greyish-white forewing costal area. Most of the rest of the forewing is a dark slate grey with some thin black streaks. There are some white areas near the outer margin. 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 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 modesta WO, more likely P. occidentalis , the Modest Sphinx or Poplar Sphinx. This large poplar/willow feeder is probably quite common in Whatcom. They are a heavy bodied species. Easily confused with P. occidentalis, which might also be present. Forewing lines more diffuse than in P. occidentalis. Pachysphinx occidentalis WO, 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. generally more southerly in Washington Paonias excaecata WO, the Blinded Sphinx The grey-blue eyespot (without a black center pupil) 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 thetis WO, 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. Hemaris thysbe WO, the Hummingbird Clearwing, Many gardeners mistake this moth for a small hummingbird as it hovers, sipping nectar from flowers through a long feeding tube. Flight is probably from late May-July and possibly again in the fall. possibility Macroglossini tribe: Hyles gallii WO, the Bedstraw Hawk Moth or Gallium Sphinx There is a broad, irregular, creamy-white band running diagonally across the dull brown forewing. There is a grey area along the fw outer margin. 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 This day flier, April-June, prefering oak woodland and pine-oak woodland in foothills, is confirmed by Bob Pyle. Moths nectar at a variety of flowers in the afternoon. Proserpinus flavofasciata WO, the Yellow-banded Day Sphinx Fw upperside is medium to dark brown with a faint to distinct white median band. Hw upperside is dark brown with a wide orange median band which may not reach the inner margin. The moth mimics a bumblebee.
