Twenty-three Sphingidae species are listed for Oregon. Not all of
the species are reported or anticipated in Lake 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 Lake County, but I
(William Oehlke) expect that this moth is present. A
USGS indicates the
moth is reported on the USGS website 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
This species is not reported, but is probably present. Larvae feed on tomatoes and go
by the common name of "Tomato Hornworms".
Although not reported from Umatilla, 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
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 not reported in Lake County.
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 Lake 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. Questionable
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 diffinis WO, the Snowberry Clearwing or Bumblebee Moth
This species is reported from Umatilla, and this day flying moth
is widely distributed in Oregon.
Arctonotus lucidus USGS, the Pacific Green
Sphinx Moth or Bear Sphinx
is recorded in Lake County.
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 Lake County, but if
you have Gallium or Epilobium, you might have
populations of this species, but it is doubtful.
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 Lake 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 afternoon.
