Dedicated as per personal communication from J. Donald Imbrie, July 16, 2011, who sends the image of
Proserpinus clarkiae above.
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 Crook 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.
This species is present (reported) 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.
Although not reported from Crook County, I suspect it is present.
I only see them occasionally on P.E.I. despite visiting lights frequently.
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
Adults fly as a single brood in the desert and in pinyon-juniper
woodland from May 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 running inwards from the apex of the wing.
It is most often found in montane woodlands and along streamcourses.
the Modest Sphinx or Poplar Sphinx,
This large poplar/willow feeder is unlikely in Crook County (generally more easterly).
They are a heavy bodied species.
This one is quite similar to Pachysphinx modesta, with modesta being smaller and darker.
There may be naturally occuring hybrids in Crook County.
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.
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.
If you have willows and poplars nearby, you've probably got populations of
the Cerisyi's Sphinx.
The hindwings are quite striking.
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.
Hemaris thetis WO, 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.
Arctonotus lucidus WO, the Pacific Green
Sphinx Moth or Bear Sphinx
is not recorded in Crooks County, but may be present in the southeast.
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 Crook County, but if
you have Gallium or Epilobium, you might have
populations of this species, but it is doubtful, generally more north easterly.
Hyles lineata WO, the White-lined Sphinx
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.

This species is not reported from Crook County, but 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
This day flier is not officially reported from Crook County and is questionable. It flies
in meadows near coniferous forests.
Enjoy some of nature's wonderments, giant silk moth cocoons.
These cocoons are for sale winter and fall. Beautiful Saturniidae moths will emerge the following spring and summer.
