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
This is generally a more southerly species, but it has been recorded
to the south and west of Genesee and may be present.
The larvae feed in large groups and are much more
spectacular than the moths.
Catalpa is the larval host.
The upperside of the forewing is pale brownish gray with wavy black
and white lines and a black-outlined white cell spot. The upperside
of the hindwing is gray with diffuse darker bands.
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.
This moth is recorded to the south in Oakland County.
Larve are not limited to pawpaw.
The upperside of the forewing is gray with heavy black bands. The
upperside of the hindwing is brownish gray with no markings. questionable
The upperside of the forewing is gray-brown with wavy lines, black
dashes, and one or two small white spots near the center of the
This large bodied moth flies in tobacco fields and vegetable gardens
(potatoes, tomatoes) and wherever host plants are found.
WO, the Carolina Sphinx
This species is not recorded in Genesee, which may be north of its
range. If you grow tomatoes, However, you might encounter it.
Larvae get very large and can strip a tomato plant. unlikely
Sphinx canadensis, the Canadian Sphinx, is not common, and is not
often reported anywhere, but it might possibly be present in Genesee
Larval hosts are white ash (Fraxinus americana) and blueberry
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.
This species is probably present in Genesee County. We have them on P.E.I.,
but I do not see them nearly as frequently as I see the other Sphingidae.
This species is probably present in Berkshire County.
Colouration and markings are highly variable from one specimen to
another. The fringes on forewing are mostly
black with some white; those on the hindwing are mostly white with a
few black patches.
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.
the Canadian Sphinx or
The upperside of the forewing is yellowish gray in males and pale
gray with a faint yellow tint in females. In both sexes, the dark
border on the outer margin widens as it approaches the inner margin.
unlikely, more northerly species
If you have blueberries in the woods, then you probably have the
Poecila Sphinx. They are pretty common here on Prince Edward Island,
but don't fly too far south of Massachusetts, being replaced by
Sphinx gordius in Connecticut. unlikely, more northerly species
This is the first Sphinx species I reared as a boy in New Jersey.
See the file for the female; she is different.
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 widespread and common. This species
ranges across North America.
The hindwings have a small blue eyespot ringed with black on a yellow
the Modest Sphinx or Poplar Sphinx,
This large poplar/willow feeder is probably present in Genesee County.
They are a heavy bodied species.
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. It
might occur in Genesee County.
This moth is widely distributed and fairly common, and it is recorded
to the south in Oakland.
Along the East Coast, it flies from P.E.I. to Florida.
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.
Slender Clearwing or Graceful Clearwing:
Gracilis is distinguished from similar species by pair of red-brown
bands on sides of thorax, varying from green to yellow-green
dorsally and sometimes brown with white below. Abdomen is red. Wings
are transparent with reddish brown borders.
SS, the Hummingbird Clearwing
This interesting day flier is confirmed for Genesee by Sherry Sleep.
They are widely distributed in the east from P.E.I. to Florida.
This moth is not reported for Genesee,
but it is fairly often reported
along the coast from southern New Jersey
to central Maine.
Note the differences between this moth and the Pandorus Sphinx.
If you have Grape or Virginia Creeper nearby, then you probably have
this species. I often get asked to identify larvae from areas where
they have not previously been reported.
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.
They are common in New Jersey and common
here on Prince Edward Island.
You will often see this species listed as Darapsa pholus,
especially in older literature.
WO, the Virginia Creeper Sphinx or the
It is widely reported as far north as southern Maine. If you have the
foodplants indicated in the common names, you probably have this
If you have hydrangea growing near a stream, then you may have the
probably is uncommon.
This species has been recorded in Genesee County.
WO, the Bedstraw Hawk Moth
or Gallium Sphinx
This species is not reported in Genesee, but it has been recorded in
counties to the south and east. I suspect it is present.
Some years I see them on P.E.I., some years, I do not. unlikely, more northerly species
Hyles lineata 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.
This moth is much more common to the south and east. It is a strong
migrant, however, and may stray to Genesee. unlikely stray
