Sphinginae subfamily
 Sphingini tribe:
  | 
Ceratomia amyntor
WO,  Elm Sphinx; 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.
 Elm (Ulmus), birch (Betula), basswood (Tilia), and 
cherry (Prunus). |   
  | 
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 forewing is gray with heavy black bands. 
The upperside of the hindwing is brownish gray with no markings. 
If you have pines, you
probably have this species. It also flies on P.E.I.
   |   
  | 
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.
 |   
  | 
This large bodied moth flies in tobacco fields and vegetable gardens 
(potatoes, tomatoes) and wherever host plants are found. 
  |   
   | 
Sphinx canadensis 
 WO, 
Sphinx canadensis, the Canadian Sphinx, is not common, and is not
 often reported anywhere, but it might possibly be present in Belknap County.
Larval hosts are white ash (Fraxinus americana) and blueberry 
(Vaccinium). 
  |   
  | 
Sphinx chersis 
WO, 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. 
  |   
  | 
Sphinx drupiferarum
 WO, the Wild Cherry 
Sphinx. Forewings, long and slender, are held close to the body when 
the moth is at rest. The top third of the forewing in the basal and median 
areas is grey while most of the rest of the forewing
is dark brown.
 |   
  | 
 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.
  |   
  | 
Sphinx luscitiosa  
 WO, 
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.
 |   
  | 
If you have blueberries in the woods, then you probably have the 
Poecila Sphinx.     |   
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 
WO,
 the Modest Sphinx or Poplar Sphinx, 
Hindwings aremostly deep maroon with some dark blue-black scaling. 
They are a heavy bodied species.
  |   
  | 
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 species ranges across North America. 
The hindwings have a small blue eyespot ringed with black on a yellow 
background.
  |   
  | 
Smerinthus cerisyi 
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. 
  |   
  | 
Smerinthus jamaicensis closely resembles Smerinthus cerisyi,
 but jamaicensis is much smaller with larger blue patches on more 
vibrant and deeper purple in the lower wings. 
  |   
Macroglossinae subfamily 
Dilophonotini Tribe:
 Visit Hemaris comparison to distinguish the following three species.
   | 
Hemaris diffinis 
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. 
  |   
  | 
Hemaris gracilis 
 WO, The Slender Clearwing or Graceful 
Clearwing 
This day flier is not commonly reported, but it might be present in
 Coos County. unlikely
  |   
  | 
Hemaris thysbe 
GDK, 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 thysbe, Laconia, August 9, 2008, Gordon D. King.
 
Philampelini Tribe:
   | 
Adults nectar from flowers of Japanese honeysuckle 
(Lonicera japonica), petunia (Petunia hybrida), mock orange 
(Philadelphus coronarius), and phlox (Phlox). 
Note the differences between this moth and the Pandorus Sphinx.
questionable, northern range limit
  |   
  | 
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. 
  |   
Macroglossini Tribe:
   | 
This day flier is widely distributed.  If you have Virginia Creeper, 
you might 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. 
The forewing upperside is dark brown to pale yellowish gray, with an 
olive green 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. 
   |   
  
  | 
Deidamia inscriptum  LSSS/IM, 
Lettered Sphinx: The moth's outer margin of the forewing is deeply scalloped. 
Light brown with dark brown markings. There is a small black and white spot near the tip. 
The upperside of the hindwing is orange-brown with a dark brown outer margin and median line.
 |   
  | 
Hyles gallii 
 WO, the Bedstraw Hawk Moth 
or Gallium Sphinx 
The thick, cream-coloured, slightly irregular, diagonal line on the 
forewing as well as the absence
of much thinner "white lines/streaks" distinguish this species from
Hyles lineata.
  |   
 
  | 
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.  |   
  | 
Proserpinus flavofasciata 
 WO, the Yellow-banded Day Sphinx:
Fw upperside is medium to dark brown with a faint to distinct white median band. 
Hw upperside is dark brown with a wide orange median band which may not reach the inner margin. The moth mimics a bumblebee. 
  |   
  | 
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. questionable
