Albany County, Wyoming
Sphingidae Larvae

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 help me develop this list with improved, documented accuracy by sending sightings (species, date, location), preferably with an image, via email to Bill Oehlke.

Please also forward your sightings to BAMONA, an excellent online resource.

Sphinginae subfamily

Sphingini Tribe:

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.

Sphinx drupiferarum WO, the 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 WO, the 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 luscitiosa WO, the Canadian Sphinx or Clemen's Sphinx

This one is reported from Richmond and from northeastern New Jersey into southern Canada.

Sphinx vashti BAMONA, 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.

Smerinthini Tribe:

Pachysphinx modesta BAMONA, the Modest Sphinx or Poplar Sphinx
It is fond of poplars and willows.

Pachysphinx occidentalis WO, the Big Poplar Sphinx

Larvae feed on cottonwood and poplar (Populus) and willow (Salix).

Larvae are very chunky with little to distinguish them from Pachysphinx modesta.

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 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.

Smerinthus cerisyi BAMONA, Cerisy's Sphinx; 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 inverted "V".

Smerinthus jamaicensis BAMONA, 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.

Macroglossinae subfamily


Dilophonotini Tribe

Hemaris diffinis WO, 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.

Hemaris thysbe 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.

Hemaris thetis WO,

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 H. thetis.

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 a darker (tan/brown) form. Note six "segmented" oblique lines.

Macroglossini Tribe

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 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 dorso-lateral lines.

Proserpinus flavofasciata WO, Yellow-banded Day Sphinx,

Larvae feed on willow weed (Epilobium) and possibly thimbleberry (Rubus parviflorus).
