Sphinginae subfamily
 Sphingini tribe:
  | 
Ceratomia amyntor
 WO, 
the Elm Sphinx or Four-horned Sphinx:
Caterpillars show both brown and green forms and are unmistakeable
due to four horns on the thorax (near the head).
Larvae feed on Elm (Ulmus), birch (Betula), basswood (Tilia), and 
cherry (Prunus). |   
  | 
Ceratomia undulosa 
WO, the Waved 
Sphinx:
Note the pinkish-orange tail, spiracles outlined in red and the cream
stripes on the head. The dramatic color change from the dorsal 
yellow-green to the lateral light greyish-blue is not always
as intense as in this image.
 |   
  | 
Dolba hyloeus 
USGS, the Pawpaw Sphinx:
Note the smooth skin, blue-black horn and small black spiracles. 
Pawpaw is the primary host. Littleleaf sweetfern, possum haw,
inkberry, tall gallberry holly and others are also utilized. 
 |   
  | 
Lapara bombycoides 
 USGS, the 
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 WO, the 
Hermit Sphinx:
Note triangular bump on the thorax.
Larval hosts are various species of beebalm (Monarda), mints (Mentha), bugleweed (Lycopis), 
and sage (Salvia). 
 |   
  | 
Manduca quinquemaculatus 
 WO, 
the Five-spotted Hawkmoth:
Note the solid black horn and dark spiracular rings. In addition to the white
oblique lines, there are fainter white rings, especially on the back.
I suspect if you grow tomatoes, you are likely to encounter it.
 |   
  
 | 
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 horn.
 |   
  | 
Sphinx chersis 
 WO, 
the Northern Ash Sphinx or Great Ash Sphinx:Note pale blue horn and the creamy-white stripes on head.
The yellow form has a red horn.
Larval hosts are ash, lilac, privet, cherry and quaking aspen. 
 |   
  | 
Sphinx drupiferarum
 WO, 
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.
 |   
  | 
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 
 This one is reported from Richmond and from northeastern New 
Jersey into southern Canada.
  |   
  | 
If you have blueberries in the woods, then you probably have the 
Poecila Sphinx.  
The green form is more common.
  |   
Smerinthini Tribe:
   | 
Amorpha juglandis 
 WO, 
the Walnut Sphinx:
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:
This moth is not officially recorded in Kennebec County. It is fond 
of poplars and 
willows and is most likely present.
  |   
  | 
Paonias astylus 
USGS, the Huckleberry Sphinx:
 It would be more common 
to the  south and is a relatively uncommon species.
Only rarely are they seen in Maine. Blueberry and huckleberry (Vaccinium), cherries (Prunus) and 
willows (Salix) are  favorite larval foodplants.
 |   
  | 
Paonias excaecata WO, 
the Blinded Sphinx:
Larvae accept willows, birches, and cherries. 
I have also found them in the wild on oak in eastern Canada.
 |   
  | 
Paonias myops WO, the 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 jamaicensis 
 WO, 
the 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.
 |   
  | 
Smerinthus cerisyi 
WO, 
Cerisy's Sphinx;
Greatly resemble modesta larvae,  pale 
green, with granular skin, pale lateral diagonal lines, faint red 
spiracular circles, very pale longitudinal lines running from  
head to  more pronounced anal diagonal line.
Larvae have green heads bounded dorsally with  pale yellow 
inverted "V".
 |   
Macroglossinae subfamily 
Dilophonotini tribe:
   | 
Hemaris thysbe
 USGS, the Hummingbird Clearwing:

from S1 to the blue horn.
Hemaris thysbe larvae feed on viburnum and related plants. 
  |   
  | 
Hemaris diffinis
 WO,  
Snowberry Clearwing; Bumblebee Moth:
 Snowberry (Symphoricarpos), 
honeysuckle (Lonicera), Coralberry, viburnums, Blue Dogbane 
(Apocynum)  dwarf bush honeysuckle (Diervilla lonicera).
Horn  black; yellow base.
 |   
  | 
Hemaris gracilis WO,  the 
Slender Clearwing or Graceful Clearwing:
Hemaris gracilis is distinguished from similar species by a pair of 
red-brown bands on the undersides of the thorax, which varies from 
green to yellow-green dorsally and sometimes brown with white 
underneath. They have a red abdomen. unlikely
 |  
 
 
 Philampelini tribe:
   | 
Eumorpha achemon
WO,   
the 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  darker (tan/brown/reddish) 
forms. Note six "segmented" oblique lines. Generally more southerly.
 |   
  | 
Eumorpha pandorus
WO,  the 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.
  |   
Macroglossini tribe:
  | 
Amphion floridensis 
 USGS,
 the 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 
 WO, the 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 
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.
 |   
  | 
Darapsa versicolor 
USGS, 
the Hydrangea Sphinx: 
Larvae feed on Smooth hydrangea (Hydrangea arborescens), 
buttonbush (Cephalanthus occidentalis), and waterwillow 
(Decodon verticillatus). 
Note small head which can be retracted into the thorax.
 |   
  | 
Deidamia inscriptum 
 WO, 
the Lettered Sphinx:
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.
  |   
  | 
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 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. 
 |   
  | 
Proserpinus flavosfasciata 
 WO, 
Yellow-banded Day Sphinx:
Penultimate instar is pale green with  pair of pale, dorsolateral lines running from head to base of short caudal horn. 
Last instar is brown-black with numerous black dots; caudal horn replaced by a black button surrounded by whitish band edged with black.
 |   
  | 
Sphecodina abbottii 
WO/RB, 
the Abbott's Sphinx:
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.
