the Elm Sphinx or 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
The upperside of the forewing is pale brownish gray with wavy black
and white lines and a black-outlined white cell spot.
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.
Forewing upperside is gray-brown with wavy lines, black dashes, and one or two small white spots near center of
the costa. Hindwing upperside is black with two white bands and a triangular black patch at the base. Note the golden hair on the thorax.
This large bodied moth flies in tobacco fields and vegetable gardens
(potatoes, tomatoes) and wherever host plants are found.
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
WO, the Northern Ash Sphinx or Great Ash
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, Jefferson, September 10, 2007, Ron White.
USGS/RW, 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.
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, August 20, 2007, Lancaster, Ron White
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.
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.
If you have blueberries in the woods, then you probably have the
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. questionable
Paonias excaecata, Crawford Notch, July 31, 2004, Deb Lievens
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.
This species ranges across North America.
The hindwings have a small blue eyespot ringed with black on a yellow
the Modest Sphinx or Poplar Sphinx,
Hindwings aremostly deep maroon with some dark blue-black scaling.
They are a heavy bodied species.
USGS, 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 closely resembles Smerinthus cerisyi,
but jamaicensis is much smaller with larger blue patches on more
vibrant and deeper purple in the lower wings.
Visit Hemaris comparison to distinguish the following three species.
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.
WO, The Slender Clearwing or Graceful
This day flier is not commonly reported, but it might be present in
Coos County. unlikely
Hemaris thysbe, North Lancaster, May 28, 2007, North Stratford, Ron White
RW, 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.
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.
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. questionable
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.
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.
WO, the Virginia Creeper Sphinx or the
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
If you have hydrangea growing near a stream, then you may have the
This species has not been recorded in Coos.
It is seen in southern Ontario, however, and in central and
southern Wisconsin and might be present.
USGS, 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
USGS, 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.
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. questionable
