For care of "found larvae/caterpillars" visit Manduca sexta larva, central Texas, August 21, 2008, Trina Woodall.

Forty-one Sphingidae species are listed for Massachusetts on the U.S.G.S. website. Not all of the species are reported or anticipated in Franklin County (Eleven are reported on U.S.G.S. as of August 29, 2008). It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the caterpillars you are likely to encounter.

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 caterpillar is present. An * indicates the moth is reported in Lepidoptera of North America, #1. Distribution of Silkmoths (Saturniidae) and Hawkmoths (Sphingidae) of Eastern North America, 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 electronic image, via email to Bill Oehlke.

This page is inspired by and dedicated to Alex Haro who sent me the images of the mature Eumorpha pandorus larva featured at page top and bottom.

Alex writes, "My family and I enjoy your website very much and use it frequently for our irregular encounters with moth larvae and adults. I hope you're willing to answer a short question: We collected a pandorus sphinx larva on our backyard virginia creeper this summer and watched grow to the last instar and orange color. I transferred it to a 6-quart tupperware container with 2" of soil in the bottom, where it buried itself about 3 weeks ago and (I presume) pupated. I would like to transfer just the pupa to a smaller container for safekeeping in the refrigerator over the winter, but am not sure how to go about isolating the pupa from the dirt/silk cell in the larger container. Any advice?"

I replied, "Just be as gentle as you can. Hopefully the soil is still fairly loose. You can probably put some newspapers over kitchen table or on an outdoor picnic table and tap corner of current storage tub so that loose soil begins to fall onto the paper.

"Gently use a spoon like a miniature shovel to work one corner of the tub toward the middle until you have unearthed the pupa. Get a piece of paper towelling about six inches square. Put the pupa perpendicular to the diagonal and begin to roll the paper around the pupae. Leave both ends open. Put a paper towel in bottom of sandwich sized ziploc tub or tupperware tub. Put two drips of water on paper towel in bottom of tub. Put pupa wrapped in paper towel in the tub, lid on tight no airholes. Put in fridge crisper mid October. Once a month check and make sure to add a drip or two of water if paper towels seem stiff and dry. They should be slightly limp. "Take out of cold storage in early May.

Write back in May and I'll tell you what to do at that time.

"I am always looking for sighting data and images to add to the site. Can you give me state and county of sighting??"

"Thanks very much for the advice - I'll start "excavating" for the pupa this evening.

"The caterpillar (last instar?) was collected in Franklin County, Massachusetts, during the first week of August.

I have attached several photographs (none of them great) of the caterpillar for your site. I can take a photo of the pupa for you as well - let me know."

Yes, the larval image is fifth instar, and I would like to display the pupa once you have unearthed it. Thanks.

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 catalpae WO, the Catalpa Sphinx

This caterpillar is one of the few North American Sphingidae that feed in large groups. Colouration is distinctive.

The larvae are much more spectacular than the moths. Catalpa is the larval host.

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 WO, 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.

Lapara coniferarum USGS, the Southern 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 jasminearum WO, the Ash Sphinx

Larvae feed on ash in the Fraxinus genus. Syringa and Ulmus have also been reported.

Note the black anal horn.

Manduca quinquemaculata 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.

Manduca sexta WO, the Carolina Sphinx

Note the red horn and black dots anterior to the white oblique lines.

If you grow tomatoes, you have probably encountered it.

Paratrea plebeja WO, the Plebeian Sphinx

Larvae feed at night, hiding on the underside of stems during the day. Preferred hosts are common trumpetcreeper (Campsis radicans), Florida yellow-trumpet (Tecoma stans), lilac (Syringa species), and passionflower (Passiflora species).

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 (darker protrusions) on pinkish 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, 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 kalmiae USGS, the Laurel Sphinx

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.

Sphinx poecila USGS, the Poecila Sphinx

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 USGS, 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 TM, the Huckleberry Sphinx

It would be more common in southern Massachusetts and is a relatively uncommon species.
Only rarely are they seen in Maine. I never saw one in New Jersey.

Paonias excaecata USGS, the Blinded Sphinx

Larvae accept willows, birches, and cherries. I have also found them in the wild on oak in eastern Canada.

Paonias myops USGS, 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 USGS, 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; Cerisyi larvae greatly resemble modesta larvae, both being pale green, with granular skin, pale lateral diagonal lines, faint red spiracular circles, and very pale longitudinal lines running from the head to a more pronounced anal diagonal line. Larvae have green heads bounded dorsally with a pale yellow inverted "V".

Lettered sphinx (Deidamia inscriptum)

Macroglossinae subfamily


Dilophonotini tribe:

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 diffinis USGS, the Snowberry Clearwing or Bumblebee Moth
Larval host plants include Snowberry (Symphoricarpos), honeysuckle (Lonicera), Coralberry, viburnums, Blue Dogbane (Apocynum) and dwarf bush honeysuckle (Diervilla lonicera). Horn is black with a yellow base.

Hemaris gracilis USGS, 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.

Eumorpha pandorus AH, 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.

Eumorpha pandorus larva (green form, top of page), early August, 2008, Alex Haro.

Macroglossini tribe:

Amphion floridensis WO, 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 WO, 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 USGS, 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.

Sphecodina abbottii WO, 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.

Many Sphingidae larvae darken considerably when they are mature and ready to pupate. The darker colouration probably camouflages them against tree/shrub bark and soil/leaf litter as they descend and excavate subterranean chambers in which to pupate.
