Sphinginae subfamily
 Sphingini tribe:
  | 
Ceratomia amyntor,
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 
cherry (Prunus). 
 |   
  | 
Ceratomia catalpae,
the Catalpa Sphinx 
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.  
Caterpillars feed gregariously on Catalpa species 
(Catalpa bignoniodes and C. speciosa).
questionable, northern range limit
 |   
  | 
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.
  |   
  | 
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. 
  |   
  | 
The upperside of the forewing is gray with heavy black bands. The 
upperside of the hindwing is brownish gray with no markings.
   |   
  |  
The upperside is of the forewing is gray with two (sometimes one or 
three) black dashes near the wing center; other markings are usually 
diffuse. The upperside of the hindwing is a uniform brown-gray.
questionable, northern 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.  
Larval hosts are various species of beebalm (Monarda), mints (Mentha),
 bugleweed (Lycopis) and sage (Salvia).   |   
  | 
The upperside of forewing is gray to grayish brown with a black line 
running from the middle of the costa to the middle of the outer 
margin; the line may be broken near the margin. There is a splash of 
brown around the cell spot.  questionable, northern range limit
  |   
  | 
Manduca quinquemaculatus, 
the Five-spotted Hawkmoth 
The moth abdomen usually has five but sometimes six pairs of yellow 
bands. The upperside of the forewing is blurry brown and gray. 
I suspect if you grow tomatoes, you are likely to encounter it.
 |   
  | 
The abdomen of the adult moth has three pairs of yellow spots. The 
upperside of the forewing is yellowish brown to deep chocolate brown 
with a dusting of white scales and zigzagged black and white lines.

  |   
  | 
The abdomen usually has six pairs of yellow bands, broken across the 
back. The sixth set of markings is quite small.
The upperside of the forewing has indistinct black, brown, and 
white markings.
   |   
  | The upperside of the forewing is gray with indistinct black and 
white markings. There is a series of black dashes 
from the base to the tip, and a small white cell spot.
   |   
  | 
Sphinx chersis, 
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. 
 Larval hosts are ash, lilac, privet, cherry, and quaking aspen. 
  |   
  | 
 Forewings, long and slender, are held close to the body when the
 moth is at rest. Larvae are beautiful and feed on cherry foliage.
  |   
  | 
  Generally this species is  
not widely reported anywhere.  Similar to S. kalmiae but 
lacks the dark bar along the fw inner margin. unlikely, more southerly
  |   
  | 
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. 
  |   
  | 
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.
  |   
  | 
Sphinx luscitiosa , 
the Canadian Sphinx or 
Clemen's Sphinx  
 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. The upperside of the hindwing is deep yellow in males, pale yellow in females; both with a wide black border. 
 |   
Smerinthini Tribe:
   | 
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. 
  |   
  | 
This moth has a large, heavy body, and females can be remarkably 
plump. 
Larvae are fond of poplars and willows.
  |   
  | , 
the Huckleberry Sphinx
This appears to be an uncommon species but may be present in Wayne 
 County.  
  |   
  | 
Named for the dull grey-blue spot (minus dark pupil) in the hindwing, 
this moth has a wide distribution and is probably common in Wayne 
County. 
I regularly see them on Prince Edward Island, and they are reported 
as far south as Florida.  |   
  | 
Named for the small eye-spot in the hindwing, this moth has a wide 
distribution and is probably common in Sussex County. 
I regularly see them on Prince Edward Island, and they are reported 
as far south as Florida.
  |   
  | 
This moth is widely distributed and fairly common.  
Along the East Coast, it flies from P.E.I. to Florida.
  |   
  | 
Smerinthus cerisyi, 
the Cerisyi's Sphinx  
Smerinthus cerisyi is found in the southern regions of all Canadian provinces and in northern border states. 
The one-eyed sphinx is also found along the U.S. west coast, eastward to the Rockies. At my home in Montague, P.E.I., Canada, they are quite common.

Macroglossinae subfamily 
Dilophonotini tribe:
 See Hemaris comparison to help distinguish
the next three species.
   | 
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.
  |   
  | 
Hemaris diffinis,  the 
Snowberry Clearwing or Bumblebee Moth  
Adults mimic bumblebees and are quite variable, both geographically 
and seasonally. The thorax is golden-brown to 
dark greenish-brown. The abdomen tends to be dark (black) with 
1-2 yellow segments just before the terminal end. 
 |   
  | 
Hemaris gracilis,  the 
Slender Clearwing or Graceful Clearwing   
Hemaris gracilis is distinguished from similar species by a pair of 
red-brown bands on the undersides of the thorax, which varies from 
green to yellow-green dorsally and sometimes brown with white 
underneath. They have a red abdomen. unlikely
  |  
 
 Philampelini tribe:
   | 
Adults nectar from flowers of Japanese honeysuckle 
(Lonicera japonica), petunia (Petunia hybrida), mock 
orange (Philadelphus coronarius), and phlox (Phlox).  
If you have Grape or Virginia Creeper nearby, then you probably have 
this species.
  |   
  | 
If you have Grape or Virginia Creeper nearby, then you probably have 
this species.
  |   
Macroglossini tribe:
  | 
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 Pennsylvania and common
here on  Prince Edward Island. 
You will often see this species listed as Darapsa pholus, 
especially in older literature. Hindwings are the same colour as the abdomen. 
  |   
  | 
Darapsa myron, the Virginia Creeper Sphinx or the 
Grapevine Sphinx
The forewing upperside is dark brown to pale yellowish gray, with an 
olive tint. On the costal margin there is a dark rectangular patch, 
although this may be reduced or absent. The upperside of the hindwing 
is pale orange. 
  |   
  |  
If you have hydrangea growing near a stream, then you may have the 
Hydrangea Sphinx. If it is present, it probably is not common.
  |   
  | 
This small species flies in the early spring. 
Grape (Vitis), ampelopsis (Ampelopsis), and Virginia creeper (Parthenocissus) all serve as larval hosts.    |   
  | 
Hyles gallii, the Bedstraw Hawk Moth 
or Gallium Sphinx  
unlikely possibility, southern range limit
  |   
  | 
The forewing upperside is dark olive brown with paler brown along the 
costa and outer margin, a narrow tan band running from the wing tip 
to the base, and white streaks along the veins.  
  |   
  | 
This moth is very much under reported  across the United States. 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. It is a strong migrant, 
however. unlikely stray
