Sphinginae subfamily
 Sphingini tribe:
  | 
Ceratomia amyntor,  Elm Sphinx; 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. |   
  | 
Ceratomia undulosa, the Waved Sphinx.
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.
 |   
  | 
Lapara bombycoides, Northern Pine Sphinx.
This caterpillar is also without the anal horn and feeds on pines.
The long stripes and reddish brown afford great camouflage.
 |   
  | 
Lintneria eremitus, Hermit Sphinx.
Note triangular bump on the thorax.
Larval hosts are various species of beebalm (Monarda), mints (Mentha), bugleweed (Lycopis), 
and sage (Salvia). 
  |   
   | 
Sphinx canadensis,  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, Northern Ash Sphinx; Great Ash 
Sphinx: Pale bluish green. Head has pair of yellow lateral bands meeting at apex. Oblique, lateral stripes 
pale, bordered anteriorly with  darker green. Ash, lilac, privet, cherry, quaking aspen.   |    
  | 
Sphinx drupiferarum, Wild Cherry Sphinx.
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. |   
  | 
Sphinx gordius, Apple Sphinx.
Larval hosts are apple (Malus), sweetfern (Myrica), Carolina rose (Rosa carolina), blueberry and huckleberry 
(Vaccinium), white spruce (Picea glauca), American larch (Larix laricina), and alder (Alnus).  |   
  | 
Sphinx kalmiae,  Laurel Sphinx.
In the final instar, the black on the head, lateral lines, horn (blue with black granulation) and on abdominal legs is diagnostic.Larvae feed primarily on 
lilac and fringe.  |   
Sphinx kalmiae, final instar burrowing, Barnhum, October 12, 2017, Gary Walton.
  | 
Sphinx luscitiosa ,  Canadian Sphinx; Clemen's Sphinx.
 Larval hosts are willow (Salix), poplar (Populus), birch (Betula), apple (Malus), ash (Fraxinus), waxmyrtle (Morella), 
and northern bayberry.  |   
  | 
Sphinx poecila, Poecila Sphinx.
If you have blueberries in the woods, then you probably have the Poecila Sphinx.  
 |   
Smerinthini Tribe:
   | 
Amorpha juglandis,  Walnut Sphinx.
Amorpha juglandis larvae feed upon Walnut and butternut (Juglans), hickory (Carya), alder (Alnus), beech (Fagus), 
hazelnut (Corylus), and hop-hornbeam (Ostrya).  |   
  | 
Paonias excaecata, Blinded Sphinx.
Larvae accept willows, birches, and cherries. I have also found them in the wild on oak in eastern Canada.  |   
  | 
Paonias myops, Small-eyed Sphinx.
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, Cerisy's Sphinx;
Pale green,  granular skin, pale lateral diagonal lines, faint red 
spiracular circles,  very pale longitudinal lines running from head to  more pronounced anal diagonal line.
Green heads bounded dorsally with  pale yellow inverted "V". |   
  | 
Smerinthus jamaicensis,  Twin-spotted Sphinx.
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,  Snowberry Clearwing; Bumblebee Moth:
 Snowberry (Symphoricarpos), honeysuckle (Lonicera), Coralberry, viburnums, Blue Dogbane 
(Apocynum). dwarf bush honeysuckle (Diervilla lonicera).
Horn black; yellow base.  |   
  | 
Hemaris gracilis,  Slender Clearwing; Graceful Clearwing.
  Larval foods are blueberries including low bush blueberry (Vaccinium vacillans), and laurel (Kalmia), all in the 
heath family (Ericaceae). range limit  |   
  | 
Hemaris thysbe,  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:
   | 
Eumorpha achemon generally more southerly ??,   Achemon Sphinx.
 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. |   
  | 
Eumorpha pandorus, Pandorus Sphinx.
If you have Grape or Virginia Creeper nearby, then you might encounter this species. Note the five large white ovals. There are 
orangey-brown and green forms also. (doubtful presence in northern Minnesota) |   
Macroglossini tribe:
  | 
Amphion floridensis, Nessus Sphinix.
In additon to Virginia creeper larvae accept Grape (Vitis), ampelopsis (Ampelopsis), and cayenne pepper (Capsicum).
Larvae are green until the final instar.   |   
  | 
Darapsa choerilus, Azalea Sphinx.
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, Virginia Creeper Sphinx; Grapevine Sphinx.
If you have the foodplants indicated in the common names, you probably have this 
species nearby.  Larvae feed on Virginia creeper (Parthenocissus quinquefolia), 
Grape (Vitis), Ampelopsis, and Viburnum. |   
 
  | 
Hyles euphorbiae, Leafy Spurge Hawk Moth 
Leafy spurge. Conspicuously colored, with  pronounced tail or "horn" near rear end. 
Young larvae variously patterned with green, yellow, black; older larvae have distinctive red, black, yellow,  white color 
pattern. Mature larvae may approach 10 cm in length; when disturbed, they regurgitate slimy green liquid. |   
  | 
Hyles gallii,  Bedstraw Hawk Moth; Gallium Sphinx.
This species is not reported in Chippewa, but it has been recorded in eastern Wisconsin counties. I suspect it is present.
 Larvae come in black and in brown forms and often feed on Epilobium (fireweed).
 |   
  | 
Hyles lineata, White-lined Sphinx.
Highly varied; feed on  great diversity of plants: 
 willow weed (Epilobium), four o'clock (Mirabilis), 
apple (Malus), evening primrose (Oenothera), elm 
(Ulmus), grape (Vitis), tomato (Lycopersicon), 
purslane (Portulaca), Fuschia. All larvae seem, however, to have the red/black swellings split by dorso-lateral lines.
