This large bodied moth flies in tobacco fields and vegetable gardens
(potatoes, tomatoes) and wherever host plants are found. |
 |
Sphinx chersis USGS, 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
Forewings, long and slender, are held close to the body when the
moth is at rest. We have them on P.E.I., but I do not see them nearly as frequently
as I see the other Sphingidae.
|
 |
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. |
 |
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. unlikely, generally more eastern species) |
Smerinthini Tribe:
 |
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. |
 |
This one is quite similar to Pachysphinx modesta, with modesta
being smaller and darker and more easterly.
Moths should be on the wing from June-August.
|
 |
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.
|
 | 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 thetis WO/EB, the Thetis Clearwing or Bee Hawk 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.
This moth is reported for nearby Josephine County, but would probably be rare
in the northern most limit of its western range, athough Edna Bottorff reports many vineyards and wild grapes
in creek bottoms, so might be locally common.
Fight would be from June to August. |
Macroglossini tribe
 |
Arctonotus lucidus WO, the Pacific Green
Sphinx Moth or Bear SphinxThis species is confirmed in nearby Josephine County.
It tends to be an early spring flier, on the wing in the
early
evening. It comes to lights at night. |
 |
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. |
 |
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 adults fly from
April-June in meadows in coniferous forests. Adults fly during the
