Sphinginae subfamily
 Sphingini tribe:
  | 
Ceratomia amyntor
WO, 
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.
 |   
  | 
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 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 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. 
  |   
  | 
The upperside of the forewing has indistinct black, brown, and white 
markings. 
If you grow tomatoes, you have probably encountered it.
Larvae get very large and can strip a tomato plant.
  |   
  
 | 
Sphinx canadensis 
 WO, 
Sphinx canadensis, the Canadian Sphinx, is not common, and is not often reported anywhere,
but it might possibly be present in Huron 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. 
  |   
 
 | 
 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 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.   They are pretty widespread throughout Michigan.
  |  
 
 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 
BAMONA,
 the Modest Sphinx or Poplar Sphinx, 
This large poplar/willow feeder is reported in Huron County.  
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 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.
  |   
  | 
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.
  |   
  | 
This moth is widely distributed and fairly common, and it is recorded 
in Huron. 
Along the East Coast, it flies from P.E.I. to Florida.
  |   
Macroglossinae subfamily 
Dilophonotini Tribe:
   | 
Hemaris diffinis 
BAMONA,
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 
BAMONA,
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 
WO,
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.
  |   
Philampelini Tribe:
   | 
Eumorpha achemon
 WO,  
the Achemon Sphinx.
Adults nectar at Japanese honeysuckle 
(Lonicera japonica), petunia (Petunia hybrida), mock 
orange (Philadelphus coronarius), and phlox (Phlox). 
Larvae feed upon Grape (Vitis), Virginia 
Creeper (Parthenocissus quinquefolia) and other vines and 
ivies (Ampelopsis). 
 |   
  | 
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 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. 
  |   
 
  | 
Darapsa myron 
WO,
the Virginia Creeper Sphinx or the 
Grapevine Sphinx 
This moth is not recorded on the U.S.G.S. site for Huron County.
It is widely reported in southern Michigan and in southern Ontario. 
If you have the foodplants indicated in the common names, you probably have this 
species nearby.  
 |   
  | 
The upperside is 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 
This species is not reported in Huron, but it has been recorded in 
Michigan counties north and south. I suspect it is present.
 Some years I see them on P.E.I., some years, I do not.
  |   
 
  | 
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.
  |   
  | 
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.
