Please help me develop this list with improved, documented accuracy by sending sightings (species, date, location), preferably with an
image, via email to Bill Oehlke.
I do not have confirmed reports of all of these species in Albany County, but I (WO) expect they are present.
For care of "found larvae/caterpillars" visit Manduca sexta larva, central Texas, August 21,
2008, Trina Woodall.
Twenty-four Sphingidae species are listed on the Bamona website for Wyoming as of August 10, 12013. Not all of the species are reported by
BAMONA or anticipated in Albany County. Six species are reported on BAMONA as of August 10, 2013 (Sphinx vashti, Pachysphinx modesta,
Paonias myops, Smerinthus cerisyi, Smerinthus jamaicensis, Hyles lineata).
It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the Sphingidae larvae you have encountered.
A WO" after the species name indicates that I have no confirmed reports of this species in your county, but I
(William Oehlke) expect that this moth is present.
A BAMONA indicates the moth is reported on the BAMONA website and/or in Moths of Western
North America, #2. Distribution of Sphingidae of Western North America, revised,
an excellent little booklet available through Paul Opler.

Please also forward your sightings to BAMONA, an excellent online resource.
Visit Albany County Adult Sphingidae.
Visit Wyoming Catocala (Underwing Moths).
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.
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.
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).
the Canadian Sphinx or
This one is reported from Richmond and from northeastern New
Jersey into southern Canada.
the Snowberry Sphinx
Larvae feed on the common snowberry (Symphoricarpos albus)
and on coralberry (S. orbiculatus).
Note the two golden
lines of slightly raised bumps, one just behind the head, the other
on the thorax.
the Modest Sphinx or Poplar Sphinx
It is fond of poplars and willows.
Larvae feed on cottonwood and poplar (Populus) and willow
Larvae are very chunky with little to distinguish them
from Pachysphinx modesta.
Larvae accept willows, birches, and cherries.
I have also found them in the wild on oak in eastern Canada.
BAMONA, 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.
Cerisyi larvae are pale
green, with granular skin, pale lateral diagonal lines, faint red
spiracular circles, and very pale longitudinal lines running from
head to more pronounced anal diagonal line.
Larvae have green heads bounded dorsally with pale yellow
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.
Snowberry Clearwing or Bumblebee Moth:
Larval host plants include Snowberry (Symphoricarpos),
honeysuckle (Lonicera), Coralberry, viburnums, Blue Dogbane
(Apocynum), dwarf bush honeysuckle (Diervilla lonicera).
Horn: black with yellow base.
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.
Larval host plants include Snowberry (Symphoricarpos),
honeysuckle (Lonicera), Coralberry, viburnums, high bush cranberry and hawthorn (Crataegus).
Horn is black with a slightly lighter base. This western species was formerly classified as
H. diffinis or H. senta. Those species west of the Continental Divide are now classified as
Larvae feed upon Grape (Vitis), Virginia Creeper
(Parthenocissus quinquefolia) and other vines and ivies
Larvae occur in both a light (green) form and a darker (tan/brown)
form. Note six "segmented" oblique lines.
WO, the Bedstraw Hawk Moth
or Gallium Sphinx
Larvae come in black and in brown forms and often feed on
BAMONA, 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
Larvae feed on willow weed (Epilobium) and possibly thimbleberry (Rubus parviflorus).
