Sphinginae subfamily
 Sphingini tribe:
  | 
Ceratomia amyntor
WO, 
the Elm Sphinx or Four-horned Sphinx: 
The fw upperside is brown with dark brown and white 
markings including white costal area near wing base, dark 
streaks along veins, and  white spot in cell. The hw upperside 
is light brown and has dark brown band along  
outer margin. Larvae feed on Elm (Ulmus), birch (Betula),
 basswood (Tilia), and cherry (Prunus).
 |   
  | 
Ceratomia undulosa 
WO, 
the Waved Sphinx 
The fw upperside is pale brownish gray with wavy black 
and white lines and a black-outlined white cell spot. The hw upperside 
is gray with diffuse darker bands.
Some individuals are very dark, almost black, and others are light 
yellowish brown. 
 |   
  | 
Dolba hyloeus 
 WO, the Pawpaw Sphinx 
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.  Larve are not limited to pawpaw.
 |   
  | 
The upperside of the forewing is gray with heavy black bands. The 
upperside of the hindwing is brownish gray with no markings. 
The underside is rather plain.
   |   
  | 
This large bodied moth flies in tobacco fields and vegetable gardens 
(potatoes, tomatoes) and wherever host plants are found. 
  |   
Fifth instar larva find in tomato garden, August 10-13, Jonathon Tubbs
 
  | 
This species was not recorded in Otsego (now confirmed by Jonathon Tubbs). It is  a strong migrant, however.
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.
The absence of white spot on each forewing and more brownish 
coloration serve to separate S. canadensis from S. poecilus. 
Hw fringe also tends to be white on poecilus and checkered 
brownish on canadensis. Larval hosts are white ash (Fraxinus 
americana) and blueberry (Vaccinium). 
 |   
  | 
Sphinx chersis BAMONA, 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.   |   
 
 | 
The grey costa and terminal area along the fw outer margin are in contrast to 
the remainder of the darker, slatey grey forewing. 
  |   
  | 
Lintneria eremitus
 WO, the 
Hermit Sphinx: 
The fw upperside is gray-brown with wavy lines, black 
dashes, and one or two small white spots near center of  
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.
 |   
  | 
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 fw upperside is yellowish gray in males and pale gray with 
faint yellow tint in females (left). The dark border on the outer 
margin widens as it approaches inner margin. Hw upperside is deep 
yellow in males, pale yellow in females with wide black 
border. |   
  | 
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.
  |   
  | 
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.
  |   
  | 
Pachysphinx modesta 
WO,
 the Modest Sphinx or Poplar Sphinx, 
This large poplar/willow feeder is reported in Oakland County.  
They are a heavy bodied species.
  |   
  | 
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. It is 
reported by Jonathan Tubbs.
  |   
  | 
This moth is widely distributed and fairly common, and it is recorded 
in Otsego. 
Along the East Coast, it flies from P.E.I. to Florida.
  |   
Macroglossinae subfamily 
Dilophonotini Tribe:
   | 
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 is probably present in
 Omegaw.   |   
  | 
Hemaris thysbe 
WO, the Hummingbird Clearwing 
This interesting day flier is not confirmed for Otsego, but is reported in neighbouring counties.
They are widely distributed in the east from P.E.I. to Florida.  |   
Philampelini Tribe:
   | 
This moth is not reported for Otsego, 
but it may be present.  
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 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 
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.   |   
 
  | 
This species has not been recorded in Otsego.
 It is seen in southern Ontario, however, and in central and southern Michigan.   |   
  | 
Hyles euphorbiae 
 TS, the Spurge Hawk Moth 
 The body is light brown with various white and dark brown 
markings, while the wings have a conspicuous tan, brown, and pink or red color pattern.

  | 
Hyles gallii 
 WO, the Bedstraw Hawk Moth 
or Gallium Sphinx 
This species is not reported in Otsego, 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.  |   
Hyles lineata (fresh at light), August 25, 2005, Jonathon Tubbs
  | 
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.
