the Elm Sphinx or Four-horned Sphinx
The upperside of the forewing is brown with dark brown and white
markings including a white costal area near the wing base, dark
streaks along the veins, and a white spot in the cell.
Larvae feed on Elm (Ulmus), birch (Betula), basswood (Tilia), and
The upperside of the forewing is pale brownish gray with wavy black
and white lines and a black-outlined white cell spot.
WO, the Pawpaw Sphinx
The upperside of the forewing is dark brown with a dusting of
white scales. Some moths have patches of reddish or yellowish
brown on the wings.
Larve are not limited to pawpaw.
This species is officially reported from Chippewa County.
If you have pines, you
probably have this species. It also flies on P.E.I.
This large bodied moth flies in tobacco fields and vegetable gardens
(potatoes, tomatoes) and wherever host plants are found.
Sphinx canadensis, the Canadian Sphinx, is not common, and is not
often reported anywhere,
but it might be present in Chippewa County.
Larval hosts are white ash (Fraxinus americana) and blueberry
LJ, 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.
Lance Johnson reports a larva find, July 13, 2007.
The lower forewings are predominantly brownish-yellow with a fairly
wide dark bar along the inner margin. At rest the wings hug the body,
giving the moth a long slender look.
If you have blueberries in the woods, then you probably have the
They are probably widespread throughout Wisconsin,
but are very much under reported.
The adults are also highly variable; sometimes wings of an individual
may be all one color or may have several colors, ranging from pale to
dark brown, and may have a white or pink tinge.
See the file for the female; she is different.
the Modest Sphinx or Poplar Sphinx,
This large poplar/willow feeder is not reported in Chippewa County, but it is probably present.
They are a heavy bodied species.
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.
This small species is probably in Chippewa County. This species ranges
across North America.
The hindwings have a small blue eyespot ringed with black on a yellow background.
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 jamaicensis closely resembles Smerinthus cerisyi, but
jamaicensis is much smaller with larger blue patches on more vibrant
and deeper purple in the lower wings.
See Hemaris comparison to help distinguish
the next three species.
WO, 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.
WO, The Slender Clearwing or Graceful
This day flier is not commonly reported, but it is confirmed
in the Lep. Soc. Season Summary.
WO, the Hummingbird Clearwing
It is not difficult to see why many gardeners would mistake an
Hemaris thysbe moth for a small hummingbird as it hovers, sipping
nectar from flowers through a long feeding tube.
This moth is not reported for Chippewa,
but it may be present.
Note the differences between this moth and the Pandorus Sphinx.
If you have Grape or Virginia Creeper nearby, then you might have
this species. I often get asked to identify larvae from areas where
they have not previously been reported. unlikely
This day flier is widely distributed. If you have Virginia Creeper,
you probably have the Nessus Sphinx.
Two bright, distinct, narrow
yellow bands are often visible on the abdomen.
The lower wings of this hawkmoth are a solid brownish-orange,
matching the body colour.
You will often see this species listed as Darapsa pholus,
especially in older literature.
WO, the Virginia Creeper Sphinx or the
The forewing upperside is dark brown to pale yellowish gray, with an
On the costal margin there is a dark rectangular patch, although
this may be reduced or absent. The upperside of the hindwing is pale
The moth's outer margin of the forewing is deeply scalloped.
The upperside is light brown with dark brown markings.
There is a small black and white spot near the tip.
The upperside of the hindwing is orange-brown with a dark brown
outer margin and median line.
WO, the Bedstraw Hawk Moth
or Gallium Sphinx
This species is not reported in Chippewa, but it has been recorded in
eastern Wisconsin counties. I suspect it is present.
Some years I see them on P.E.I., some years, I do not.
WO, 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.
This moth is very much under reported on USGS. It is a
rapid day flier so is probably not in too many collections.
Grape is a popular larval host.
