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. The upperside of the hindwing is light brown and has a dark brown band along the outer margin.
Larvae feed on Elm (Ulmus), birch (Betula), basswood (Tilia), and
The upperside of the forewing is yellowish brown with no white markings, but there are indistinct black lines and dashes. The cell spot is gray with a black outline and the upperside of the hindwing is yellowish brown with obscure lines.
The body is gray, spindle-shaped, and 30-35mm long.
Catalpa is the larval host.
the Waved Sphinx.
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.
Some individuals are very dark, almost black, and others are light yellowish brown.
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.
The upperside of the forewing is gray with heavy black bands. The upperside of the hindwing is brownish gray with no markings.
If you have pines, you
might have this species. It flies on P.E.I. questionable, southern range limit

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 costa. The upperside of the hindwing is
black with two white bands and a triangular black patch at the base. Note the golden hair on the thorax.
This large bodied moth flies in tobacco fields and vegetable gardens
(potatoes, tomatoes) and wherever host plants are found.
This species is now recorded in Ingham, which is just north of
its reported range.
If you grow tomatoes, you have possibly encountered it.
Larvae get very large and can strip a tomato plant.
The absence of the white spot on each forewing and the more brownish coloration serve to separate canadensis from S. poecilus.
The hindwing fringe also tends to be white on poecilus and checkered brownish on canadensis.
Larval hosts are white ash (Fraxinus americana) and blueberry
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.
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.
The upperside of the forewing ranges from brown with black borders through brownish gray with paler
borders to pale gray with no borders. Dashes, submarginal line, and cell spot are usually weak.
Note the pm line, absent in Sphinx poecila which flies
more to the north. questionable, northern range linmit
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
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.

the Walnut Sphinx.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. Patterns range from faint to pronounced.
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.
Flight would be June-July.

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.

Along the East Coast, it flies from P.E.I. to Florida.
USGS, 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.
Hemaris gracilis WO, the
Slender Clearwing or Graceful Clearwing
Hemaris gracilis is distinguished from similar species by a pair of red-brown bands on the sides of the thorax, which varies
from green to yellow-green dorsally and sometimes brown with white underneath. They have a red abdomen.
Hemaris thysbe USGS, the Hummingbird Clearwing
This interesting day flier is confirmed for Ingham.
They are widely distributed in the east from P.E.I. to Florida.
This moth is not reported for Eaton County,
but it should be present. 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.
Eumorpha pandorus. Lansing, September 9, 1999, Harry D. King.
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.

The moth's outer margin of the forewing is deeply scalloped.

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 occasionally strays to Eaton County.
