Sphinginae subfamily
 Sphingini tribe:
  | 
This moth is a very strong flier, but would only make its way to
Ontario County as a rare stray. There are not too many records from 
New York state, but records exist for NJ and CT.

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. 
  |   
  | 
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.  doubtful
  |   
  | 
This moth is not reported from Ontario, but it is  
reported to the north, east, south and west. If you have pines, you
probably have this species. It flies on P.E.I.
   |   
  | 
 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.
   |   
  | 
Manduca quinquemaculatus 
USGS, 
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.
 |   
  | 
Manduca sexta 
 USGS, the Carolina Sphinx 
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.
If you grow tomatoes, however, you may have encountered it as it has 
been found in western N.Y.

 | 
Sphinx canadensis 
 WO, 
Sphinx canadensis, the Canadian Sphinx, is not common, and is not 
often reported anywhere,
but it might  be present in Ontario County as it is reported from 
southern Ontario, Canada.
Larval hosts are white ash (Fraxinus americana) and blueberry 
(Vaccinium). 
  |   
  | 
Sphinx chersis 
 USGS, the Northern Ash Sphinx or Great Ash Sphinx
This species is present but may not 
be common. Larval hosts are ash, lilac, privet, cherry, and quaking 
aspen. 
   |   
  | 
 This species is officially reported in Chautauqua. We have them 
on P.E.I., but I do not see them nearly as frequently
as I see the other Sphingidae.  |   
  | 
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 Chautauqua County, but it may be present.
 It is generally not common.

  |   
  | 
If you have blueberries in the woods, then you might have the 
Poecila Sphinx.
They are pretty common here on Prince Edward Island. It has been 
confirmed in Chautauqua County.   |   
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. 
See the file for the female; she is different.  |   
  | 
Pachysphinx modesta
 USGS/BB,  
the Modest Sphinx or Poplar Sphinx  
This moth is recorded in Chautauqua County. It 
is fond of poplars and 
willows.
They are common on Prince Edward Island.
  |   
Pachysphinx modesta, July 19-20, 2009, Beth Boyle.
  | 
Named for the dull grey-blue spot (minus dark pupil) in the hindwing, 
this moth has a wide distribution and is probably common in Chautauqua 
County. 
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 Chautauqua 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. At my home 
in Montague, P.E.I., Canada, they are quite common.
 |   
  | 
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 with 
 1-2 yellow segments on the abdomen. 
  |   
  | 
Hemaris gracilis
 USGS,  the 
Slender Clearwing or Graceful Clearwing  
This day-flying moth is less common, but it has been recorded in 
Chautauqua County.
  |  
 
 Philampelini tribe:
   | 
This moth is reported for Chautauqua, and 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 not 
previously reported.
  |   
Macroglossini tribe:
  | 
This day flier is widely distributed.  If you have Virginia Creeper, 
you probably have the Nessus Sphinx. It is officially reported 
from Chautauqua.  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.   It is confirmed for Chautauqua County.
  |   
 
  | 
Darapsa myron 
USGS, the Virginia Creeper Sphinx or the Grapevine Sphinx 
This moth is  recorded on the U.S.G.S. site for Chautauqua County. 
 
It is widely reported as far north as southern Maine. If you have the 
foodplants indicated in the common names, you probably have this 
species nearby.   |   
  |  
If you have hydrangea growing near a stream, then you may have the 
Hydrangea Sphinx.  It has not been reported in Chautauqua Co., 
but is likely there.
   |   
 
  | 
This species has been recorded in Chatauqua County.
 
Larvae feed on grape foliage and on Virginia Creeper. 
  |   
  | 
Hyles gallii 
 USGS, the Bedstraw Hawk Moth 
or Gallium Sphinx 
This species is reported in Chautauqua County. 
 Some years I see them on P.E.I., some years, I do not.
  |   
  | 
Hyles lineata 
 USGS, the White-lined Sphinx
This species is reported from Chautauqua County. It flies across 
southern New York and has strong migrating tendancies.
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.
