Sphinginae subfamily
 Sphingini tribe:
  | 
Ceratomia amyntor
 WO, 
the Elm Sphinx or Four-horned Sphinx
Larvae feed on Elm (Ulmus), birch (Betula), basswood 
(Tilia), and cherry (Prunus).
There are both green and brown forms. The four horns near 
the head are diagnostic.  |   
  | 
Fraxinus, Ligustrum, Quercus, Crataegus and 
Chionanthus virginicus are  listed as hosts. 
In the fifth instar, the spiracular ovals are decidedly red and the 
anal horn is off-white to pinkish laterally.
  |   
  | 
This caterpillar is also without the anal horn and feeds on pines. 
The long stripes and reddish brown afford great camouflage.
   |   
  | 
Note triangular bump on the thorax.
 
Larval hosts are various species of beebalm (Monarda), mints (Mentha), bugleweed (Lycopis), 
and sage (Salvia). 
  |   
Lintneria eremitus fifth instar, August 28, 2012, Cindy Mead
 
  | 
The caterpillars are called Tomato Hornworms and each has a black horn at the end of the abdomen. 
 Larvae feed on potato, tobacco, tomato, and other plants in the 
nightshade family (Solanaceae). 
  |   
  
 | 
Sphinx canadensis 
 WO, 
Sphinx canadensis, the Canadian Sphinx.
This species is not common at lights, and is not 
often reported anywhere. 
Larval host may be exclusively black ash (Fraxinus nigra).
Variable appearance but always with granulous (darker protrusions) on pinkish horn.
  |   
  | 
Sphinx chersis 
 BAMONA, the Northern Ash Sphinx or Great Ash 
Sphinx: 
The larvae are pale bluish green. The head has a pair of yellow 
lateral bands meeting at the apex. The oblique, lateral stripes are 
pale and bordered anteriorly with a darker green. 
Larval hosts are ash, lilac, privet, cherry, and quaking aspen. 
  |    
  | 
Larvae hide in the day and feed primarily on cherry, plum, and apple 
at night. Larvae have been found on Amelanchier nantuckensis
 in Massachusetts and have been reared to pupation in Michigan on 
Prunus serotina. Note purple oblique lines.
  |   
  | 
In the final instar, the black on the head, lateral lines, horn and on abdominal 
legs is diagnostic. Larvae feed primarily on lilac and fringe.
  |   
  | 
Sphinx luscitiosa  
 WO, 
the Canadian Sphinx or 
Clemen's Sphinx 
 Larval hosts are  willow 
(Salix), poplar (Populus), birch (Betula), 
apple (Malus), ash (Fraxinus), waxmyrtle 
(Morella), and northern bayberry. 
  |   
  | 
If you have blueberries in the woods, then you might have the 
Poecila Sphinx.   The green form is more common.
  |   
Smerinthini Tribe:
   | 
Amorpha juglandis larvae feed upon Walnut and butternut (Juglans),
 hickory (Carya), alder (Alnus), beech (Fagus), 
hazelnut (Corylus), and hop-hornbeam (Ostrya).   |   
  | 
Pachysphinx modesta
 WO,  
the Modest Sphinx or Poplar Sphinx 
Larvae feed on poplars and cottonwood. 
Anal horn all but disappears in final instar.
  |   
  | 
Larval skin is grainy in appearance. 
Larvae accept willows, birches, and cherries. 
I have also found them in the wild on oak in eastern Canada. 
  |   
  | 
Wild cherry species are the favorites as larval foodplants, but eggs 
will also be deposited on birches and other forest trees. 
There are varying degrees in the amount of red markings along the sides. 
  |   
  | 
Smerinthus cerisyi 
WO, 
Cerisy's Sphinx;
Cerisyi larvae greatly resemble modesta larvae, both being pale 
green, with granular skin, pale lateral diagonal lines, faint red 
spiracular circles, and very pale longitudinal lines running from the 
head to a more pronounced anal diagonal line.
Larvae have green heads bounded dorsally with a pale yellow 
inverted "V".
 |   
  | 
Larvae feed upon many forest trees including birches and cherries, 
but are expecially fond of poplars and willows. Red markings on sides
vary greatly from specimen to specimen.
  |   
Macroglossinae subfamily 
Dilophonotini Tribe:
  | 
Hemaris diffinis
 WO,  
the 
Snowberry Clearwing or Bumblebee Moth  
Larval host plants include Snowberry (Symphoricarpos), 
honeysuckle (Lonicera), Coralberry, viburnums, Blue Dogbane 
(Apocynum) and dwarf bush honeysuckle (Diervilla lonicera).
Horn is black with a yellow base.
  |   
  | 
Hemaris gracilis
 WO,  the 
Slender Clearwing or Graceful Clearwing  
  Larval foods are blueberries including low bush blueberry 
(Vaccinium vacillans), and laurel (Kalmia), all in the 
heath family
(Ericaceae).
  |   
  | 
Hemaris thysbe 
WO, the Hummingbird Clearwing 
There is also an orangey-pink prepupal form. The lateral line runs 
from S1 to the blue horn. 
Hemaris thysbe larvae feed on viburnum and related plants.  
  |   
Philampelini Tribe:
   | 
 Larvae feed upon Grape (Vitis), Virginia Creeper 
(Parthenocissus quinquefolia) and other vines and ivies 
(Ampelopsis). 
Larvae occur in both a light (green) form and a darker (tan/brown) 
form. Note six "segmented" oblique lines.
  |   
Macroglossini Tribe:
   | 
In additon to Virginia creeper larvae accept Grape (Vitis), 
ampelopsis (Ampelopsis), and cayenne pepper (Capsicum).
 Larvae are green until the final instar. 
  |   
  | 
Larvae feed on Azalea and Viburnum and progress very rapidly. The 
larva to the left on Viburnum cassinoides is getting ready to 
pupate. Color change from green to light burgundy-brown indicates 
pupation is imminent.  
  |   
 
  | 
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. 
Larvae feed on Virginia creeper (Parthenocissus quinquefolia), 
Grape (Vitis), Ampelopsis, and Viburnum.
  |   
  |  
Larvae feed on Smooth hydrangea (Hydrangea arborescens), 
buttonbush (Cephalanthus occidentalis), and waterwillow 
(Decodon verticillatus).  
Note small head which can be retracted into the thorax. not common
  |   
  | 
Grape (Vitis), ampelopsis (Ampelopsis), and 
Virginia creeper (Parthenocissus) all serve as larval hosts. 
The alternating yellow and greyish-green rings across the back 
distinguish this larva. questionable as larva, northern range limit
  |   
  | 
Hyles euphorbiae 
 TS, Leafy Spurge Hawk Moth 
Larvae feed on leafy spurge. Larvae are also conspicuously colored, with a 
pronounced tail or "horn" near rear end. 
Young larvae are variously patterned with green, yellow, and black; 
older larvae have distinctive red, black, yellow, and white color 
pattern. Mature larvae may approach 10 cm in length; when disturbed, 
they regurgitate a slimy green liquid.

Hyles euphorbiae mature larva, September 12, 2015, Trina Sweet
  | 
Hyles gallii 
 WO, the Bedstraw Hawk Moth 
or Gallium Sphinx:
Larvae come in black and in brown forms and often feed on
Epilobium (fireweed). 
  |   
Hyles gallii, Fife Lake, September 11, 2008, Patty Burwell.
 
  | 
Hyles lineata 
 WO, the White-lined Sphinx
Larvae are highly varied and feed on a great diversity of plants 
including willow weed (Epilobium), four o'clock (Mirabilis), 
apple (Malus), evening primrose (Oenothera), elm 
(Ulmus), grape (Vitis), tomato (Lycopersicon), 
purslane (Portulaca), and Fuschia.  
All larvae seem, however, to have the red/black swellings split by
dorso-lateral lines. 
  |   
  | 
Larvae feed at night on grape (Vitis) and ampelopsis 
(Ampelopsis) and hide on the bark of their host plants during 
the day.  Virginia creeper would also be a suitable host.  There is also a dark form
without the green patches. Note the "raised eye", replacing the anal horn.
