Sphinginae subfamily
 Sphingini tribe:
  | 
 Agrius cingulata,  
WO Pink-spotted hawkmoth,
 possible but unlikely stray
This species is a strong migrant and adults nectar from 
deep-throated flowers including moonflower (Calonyction aculeatum), 
morning glory (Convolvulus), honey suckle (Lonicera) 
and petunia (Petunia species).  
  |   
  | 
Ceratomia amyntor
 USGS, 
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).
  |   
  | 
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. 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.
  |   
  | 
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.
  |   
  | 
 If you have pines, you
might have this species. It flies on P.E.I. 
The upperside of the forewing is gray with heavy black bands. The upperside of the hindwing is brownish gray with no markings.

   |   
  | 
Lintneria eremitus WO, the 
Hermit Sphinx 
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.
 |   
  | 
I suspect if you grow tomatoes, you are likely to encounter Manduca quinquemaculata.
  |   
  | 
If you grow tomatoes, you have probably encountered Manduca sexta 
in the larval stage. 
Larvae get very large and can strip a tomato plant.
   |   
  | 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  USGS, the Northern Ash Sphinx or Great Ash Sphinx
 Larval hosts are ash, 
lilac, privet, cherry, and quaking aspen. 
   |   
  | 
 We have them 
on P.E.I., but I do not see them nearly as frequently
as I see the other Sphingidae.
  |   
  | 
 
Note the pm line, absent in Sphinx poecila which flies
more to the north.
  |   
  | 
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  
 WO, 
the Canadian Sphinx or 
Clemen's Sphinx 
 This one is not reported from Cuyahoga County, but it is a  possibility
  |   
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.
See the file for the female; she is different.
  |   
  | 
Pachysphinx modesta
 USGS,  
the Modest Sphinx or Poplar Sphinx 
This moth has a large, heavy body, and females can be remarkably plump.
  |   
  | 
This appears to be an uncommon species.  They might be present in Summit County.  
  |   
  | 
Named for the dull grey-blue spot (minus dark pupil) in the hindwing, 
this moth has a wide distribution  in the eastern United States. 
I regularly see them on Prince Edward Island, and they are reported 
as far south as Florida.
  |   
  | 
Paonias myops
 USGS, the Small-eyed Sphinx 
Named for the small eye-spot in the hindwing, this moth has a wide 
distribution and is probably common in Licking County. 
I regularly see them on Prince Edward Island, and they are reported 
as far south as Florida.
  |   
  | 
Smerinthus cerisyi
 WO, 
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. 
 maybe, but generally a more northerly species.
 |   
  | 
This moth is widely distributed and fairly common.  
Along the East Coast, it flies from P.E.I. to Florida.
  |   
Macroglossinae subfamily 
Dilophonotini tribe:
 See Hemaris comparison to help distinguish
the next three species.
   | 
Hemaris thysbe 
 USGS, 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.
  |   
  | 
Hemaris diffinis
 USGS,  the 
Snowberry Clearwing or Bumblebee Moth  
Adults mimic bumblebees and are quite variable. The wings are basically clear, with dark brown to 
brownish-orange veins, bases and edges. The thorax is golden-brown to 
dark greenish-brown. The abdomen tends to be dark (black) with 1-2 
yellow segments before the tip. 
 |   
  | 
Hemaris gracilis
 WO,  the 
Slender Clearwing or Graceful Clearwing:
Hemaris gracilis has a pair of red-brown bands on the sides of the thorax. 
Abdomen is red.
Wings are transparent with reddish brown borders. Outer edge of forewing transparent area is even and forewing cell has median row of scales. 
Note red coloration on dorsal surface of legs.
 |  
 
 Philampelini tribe:
   | 
 Larvae get large and feed on grape vines and Virginia creeper. 
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 not 
previously reported. 
  |   
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.

  | 
 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.   |   
 
  | 
Darapsa myron 
 WO, the Virginia Creeper Sphinx or the Grapevine Sphinx 
 If you have the 
foodplants indicated in the common names, you probably have this 
species nearby. The lower wings are orange. 
  |   
  | 
Darapsa versicolor 
 WO, 
the Hydrangea Sphinx: 
If you have hydrangea growing near a stream, then you might have the 
Hydrangea Sphinx.  FW upperside is often greenish brown with curved dark lines and pinkish-white patches. 
HW upperside is pale yellow to reddish brown with white along costal margin, greenish brown along outer margin, 
and white shaded with greenish brown on inner margin. 
 |   
 
  | 
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. 
Grape (Vitis), ampelopsis (Ampelopsis), and Virginia creeper (Parthenocissus) all serve as larval hosts. 
  |   
  | 
Hyles lineata  USGS, the White-lined Sphinx
This species has 
strong migrating tendancies from much further south.
There are records from New Hampshire and Maine. 
  |   
  | 
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.
