Hood River County

Sphingidae

Twenty-three Sphingidae species are listed in the USGS for Oregon. Not all of the species are reported (only three by USGS, Hemaris thysbe, Hemaris diffinis and Hyles lineata) or anticipated in Hood River 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 Hood River County, but I (William Oehlke) expect that this moth is 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 large bodied moth flies in tobacco fields and vegetable gardens (potatoes, tomatoes) and wherever host plants are found.

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 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.

Sphinx vashti WO, the Snowberry Sphinx,

Snowberry Sphinx adults fly as a single brood in montane woodlands and along prairie streamcourses from April to August.
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 at the apex.

Smerinthini Tribe:

Paonias excaecata WO, the Blinded Sphinx,

The outer margin of the forewing is quite wavy. There is a dark cell spot and a dark oblique line mid wing from the costa almost to the inner margin. Basic ground colour is pinkish brown.

Flight would be June-July.

Smerinthus cerisyi WO, 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 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, directly above. S. ophthalmica has smoother scalloping of the fw outer margin.

Macroglossinae subfamily


Dilophonotini tribe

Hemaris thysbe USGS, 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.

Hemaris diffinis USGS, 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.

Macroglossini tribe

Hyles gallii WO, the Bedstraw Hawk Moth or Gallium Sphinx

Larvae feed on Epilobium angustifolium and Galium.

I expect flight is late May-July with a possible fall flight as well.

Hyles lineata USGS, the White-lined Sphinx

Adults usually fly at dusk, during the night, and at dawn, but they also fly during the day over a wide variety of open habitats including deserts, suburbs, and gardens.

Proserpinus clarkiae WO, 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.

Proserpinus flavofasciata WO, the Yellow-banded Day Sphinx,

Proserpinus flavofasciata adults fly from April-June in meadows in coniferous forests. Adults fly during the afternoon, nectaring from lilac, dandelion, cherry, etc.
