Comments, suggestions and/or additional information/sightings are welcomed by Bill.

The page is inspired by and dedicated to John Rosendale (Monmouth County), New Jersey. John has sent the Xylophanes tersa larval image at top of page.
For care of "found larvae/caterpillars" visit Manduca sexta larva, central Texas, August 21, 2008, Trina Woodall.
Forty-four Sphingidae species are listed for New Jersey on the U.S.G.S. website. Not all of the species are reported or anticipated in Monmouth County (twenty-seven are reported on U.S.G.S. as of August 31, 2010). 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 (William Oehlke) expect that this moth is present or might be present, although unreported.
The USGS report includes both Enyo lugubris and Cautethia grotei which occasionally are taken in Monmouth County as adult strays, but I do not think there would be breeding/overwintering populations anywhere in New Jersey, and hence no larvae to be encountered.
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.

Ceratomia amyntor USGS, 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 USGS, 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 USGS, 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 USGS, 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 WO, 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 quinquemaculatus USGS, 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 USGS, 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 USGS, 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 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 USGS, 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 franckii WO, Franck's Sphinx Moth. Larvae feed exclusively on various species of ash (Fraxinus).
Raised, pointed bumps, especially near the head and thorax give this caterpillar a reptilian appearance.

Sphinx gordius USGS, 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.

Smerinthini Tribe:

Amorpha juglandis USGS, 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 WO, the Modest Sphinx or Poplar Sphinx. This moth is not officially recorded in Monmouth County. It is fond of poplars and willows.

Paonias astylus USGS, the Huckleberry Sphinx. Blueberry and huckleberry (Vaccinium), cherries (Prunus) and willows (Salix) are the favorites as larval foodplants.

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.

Macroglossinae subfamily

Dilophonotini tribe:

See Hemaris comparison to help distinguish the next three species.

Hemaris thysbe USGS, 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 hosts 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 WO, 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.

Philampelini tribe:

Eumorpha achemon USGS, 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.

Eumorpha pandorus USGS, 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.

Macroglossini tribe:

Amphion floridensis USGS, 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 USGS, 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 USGS, 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 lineata USGS, 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.

Xylophanes tersa JR/USGS, the Tersa Sphinx. Larvae feed on Borreria, Catalpa and Manettia spp. and Smooth buttonplant (Spermacoce glabra) and starclusters (Pentas species). They are also recorded on joe-pie weed and Hamelia patens and on Hedoydis nigricans. The green form may be more common.
