Sphinginae subfamily

Sphingini tribe:

Ceratomia amyntor WO, Elm Sphinx; 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. Larvae feed on Elm (Ulmus), birch (Betula), basswood (Tilia), and cherry (Prunus).

Ceratomia catalpae WO, the Catalpa Sphinx
The upperside of the forewing is yellowish brown with no white markings, but there are indistinct black lines and dashes. The cell spot is gray with a black outline and the upperside of the hindwing is yellowish brown with obscure lines. Catalpa is the larval host.

Ceratomia undulosa WO, the Waved Sphinx
The upperside of the forewing is pale brownish gray with wavy black and white lines and a black-outlined white cell spot.

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.

Lapara bombycoides WO, the Northern Pine Sphinx
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 probably have this species. It also flies on P.E.I.

Lintneria eremitus WO, Hermit Sphinx: Fw upperside gray-brown with wavy lines, black dashes, one or two small white spots near center of the costa. Hw upperside black with two white bands and a triangular black patch at the base. Note the golden hair on the thorax.

Manduca quinquemaculatus WO, Five-spotted Hawkmoth: This large bodied moth flies in tobacco fields and vegetable gardens (potatoes, tomatoes) and wherever host plants are found.

Manduca sexta WO, the Carolina Sphinx
The abdomen usually has six pairs of yellow bands, broken across the back. The sixth set of markings is quite small. The upperside of the forewing has indistinct black, brown, and white markings. If you grow tomatoes, however, you may encounter it.

Sphinx canadensis WO, Sphinx canadensis, the Canadian Sphinx, is not common, and is not often reported anywhere, but it might possibly be present in Belknap 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.

Sphinx drupiferarum WO, the Wild Cherry Sphinx. Forewings, long and slender, are held close to the body when the moth is at rest. The top third of the forewing in the basal and median areas is grey while most of the rest of the forewing is dark brown.

Sphinx gordius WO, the Apple Sphinx

Colouration and markings are highly variable from one specimen to another. The fringes on forewing are mostly black with some white; those on the hindwing are mostly white with a few black patches.

Sphinx kalmiae WO, the Laurel Sphinx
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.

Sphinx poecila WO, the Poecila Sphinx
If you have blueberries in the woods, then you probably have the Poecila Sphinx.

Smerinthini Tribe:

Amorpha juglandis WO, the Walnut Sphinx
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. See the file for the female; she is different.

Paonias astylus WO, the Huckleberry Sphinx
This appears to be an uncommon species.
They are not officially recorded for your county but it should be present.

Paonias excaecata WO, Blinded Sphinx: 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.

Paonias myops WO, the Small-eyed Sphinx
This species ranges across North America.
The hindwings have a small blue eyespot ringed with black on a yellow background.

Pachysphinx modesta WO/BM, the Modest Sphinx or Poplar Sphinx,
Hindwings aremostly deep maroon with some dark blue-black scaling. They are a heavy bodied species.
Pachysphinx modesta Cornish, on route 120, June 19, 2014, Butch McCarthy

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.

Smerinthus jamaicensis WO, the Twin-spotted Sphinx
Smerinthus jamaicensis closely resembles Smerinthus cerisyi, but jamaicensis is much smaller with larger blue patches on more vibrant and deeper purple in the lower wings.

Macroglossinae subfamily

Dilophonotini Tribe:

Visit Hemaris comparison to distinguish the following three species.

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 it might be present in Coos County. unlikely

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 from flowers of Japanese honeysuckle (Lonicera japonica), petunia (Petunia hybrida), mock orange (Philadelphus coronarius), and phlox (Phlox). Note the differences between this moth and the Pandorus Sphinx.

Eumorpha pandorus WO, 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:

Amphion floridensis WO, the Nessus Sphinix
This day flier is widely distributed. If you have Virginia Creeper, you might have the Nessus Sphinx.
Two bright, distinct, narrow yellow bands are often visible on the abdomen.

Darapsa choerilus WO, the Azalea Sphinx.
The lower wings of this hawkmoth are a solid brownish-orange, matching the body colour.
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. The forewing upperside is dark brown to pale yellowish gray, with an olive green tint. On the costal margin there is a dark rectangular patch, although this may be reduced or absent. The upperside of the hindwing is pale orange.

Darapsa versicolor WO, the Hydrangea Sphinx
If you have hydrangea growing near a stream, then you may have the Hydrangea Sphinx.

Deidamia inscriptum WO, the Lettered Sphinx: The moth's outer margin of the forewing is deeply scalloped. 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
The thick, cream-coloured, slightly irregular, diagonal line on the forewing as well as the absence of much thinner "white lines/streaks" distinguish this species from Hyles lineata.

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.

Sphecodina abbottii WO, the Abbott's Sphinx: 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.
