Cook County, Illinois
Sphingidae Larvae

Ceratomia undulosa larva, Oak Lawn, Cook County, Illinois,
July 7, 2008, courtesy of Benjamin Bush.

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

Forty-two Sphingidae species are listed in the USGS for Illinois. Not all of the species are reported (thirty-three by USGS as of July 9, 2008) or anticipated (twenty-seven by Bill Oehlke) in Cook County.

This page is inspired by and dedicated to Benjamin Bush. who found the Ceratomia undulosa larva on July 7, 2008, in Oak Lawn.

Ben writes, "First of all, thanks for your helpful and thorough identification site. Within twenty seconds had my guy.

"OK, so my story is that I found this C. undulosa crawling up the bricks beside my entryway door upon my return home from work. I rescued the little guy (or girl!) and transferred him/her to a tree via my book. I would estimate this particular specimen to be 3-3.5 inches long, with quite the horn at the end!

"I took quite a few pictures, and wanted to share them with you not only to peruse, but to use, if you'd like on your C. undulosa page.

"I didn't get one single picture with great head and tail in his natural surroundings, though. These have such great color and detail; hopefully you can use one!

"Again, thanks for your site -- it's really useful!"

It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the larvae you have encountered.

A WO" after the species name indicates that I have no confirmed reports of this species in Cook County, but I (William Oehlke) expect that this species is present.

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.

Sphinginae subfamily Sphingini tribe: Pink-spotted hawkmoth (Agrius cingulata) USGS Non-resident; present only as an adult moth fall stray Ceratomia amyntor USGS, the Elm Sphinx or Four-horned Sphinx Larvae feed on Elm (Ulmus), birch (Betula), basswood (Tilia), and cherry (Prunus). There are both green and brown forms. The four horns near the head are diagnostic. Ceratomia catalpae WO, the Catalpa Sphinx Young caterpillars feed gregariously on Catalpa species (Catalpa bignoniodes and C. speciosa) in the Bignoniaceae family, skeletonizing the foliage. Larvae are mostly white in early instars. generally more eastern species Ceratomia hageni WO, Hagen's Sphinx or Osage Orange Sphinx Larvae feed on osage orange (Maclura pomifera), and they have a granulous appearance with variable amounts of purple along the oblique white stripes. Ceratomia undulosa BB/USGS, the Waved Sphinx Fraxinus, Ligustrum, Quercus, Crataegus and Chionanthus virginicus are listed as hosts. In the fifth instar, the spiracular ovals are decidedly red and the anal horn is off-white to pinkish laterally. Ceratomia undulosa, Oak Lawn, July 7, 2008, Ben Bush Dolba hyloeus USGS, the Pawpaw Sphinx Larvae feed on pawpaw (Asimina triloba), littleleaf sweetfern (Myrica aspleniifolia), possum haw (Ilex decidua), and inkberry (Ilex glabra) as well as Tall Gallberry Holly (Ilex coriacea). Lapara bombycoides WO, 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. 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 USGS, the Five-spotted Hawkmoth The caterpillars are called Tomato Hornworms and each has a black horn at the end of the abdomen. Larvae feed on potato, tobacco, tomato, and other plants in the nightshade family (Solanaceae). Manduca sexta USGS, the Carolina Sphinx Tobacco Hornworms, equipped with a red-tipped horn at the end of the abdomen, are true gluttons and feed on tobacco and tomato, and occasionally potato and pepper crops and other plants in the nightshade family (Solanaceae). Cluentius sphinx (Neococytius cluentius) USGS Non-resident; present only as an adult moth fall stray Paratrea plebeja WO, the Plebeian Sphinx Preferred hosts are common trumpetcreeper (Campsis radicans), Florida yellow-trumpet (Tecoma stans), lilac (Syringa species), and passionflower (Passiflora species). The anal horn is blue, preceded by a yellow dash. Sphinx canadensis WO, Sphinx canadensis, the Canadian Sphinx, is not common, and is not often reported anywhere, but it might be present in Cook County. Larval hosts are white ash (Fraxinus americana) and blueberry (Vaccinium). Sorry, no larval image available. Sphinx chersis USGS, the Northern Ash Sphinx or Great Ash Sphinx: The larvae are pale bluish green. The head has a pair of yellow lateral bands meeting at the apex. The oblique, lateral stripes are pale and bordered anteriorly with a darker green. 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. Lintneria eremitus USGS, the Hermit Sphinx Note triangular bump on the thorax. Larval hosts are various species of beebalm (Monarda), mints (Mentha), bugleweed (Lycopis), and sage (Salvia). 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 USGS, the Canadian Sphinx or Clemen's Sphinx Larval hosts are willow (Salix), poplar (Populus), birch (Betula), apple (Malus), ash (Fraxinus), waxmyrtle (Morella), and northern bayberry. Sphinx poecila USGS, the Poecila Sphinx If you have blueberries in the woods, then you probably have the Poecila Sphinx. They are probably widespread throughout Ilinois, but are very much under reported. 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 USGS, the Modest Sphinx or Poplar Sphinx Larvae feed on poplars and cottonwood. 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: Titan sphinx (Aellopos titan) USGS Non-resident; present only as an adult moth fall stray Ello sphinx (Erinnyis ello) USGS Non-resident; present only as an adult moth fall stray Obscure sphinx (Erinnyis obscura) USGS Non-resident; present only as an adult moth fall stray See Hemaris comparison to help distinguish the next two species. 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 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. generally more eastern species 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 USGS, 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 USGS, the Bedstraw Hawk Moth or Gallium Sphinx This species is not reported in Chippewa, but it has been recorded in eastern Wisconsin counties. I suspect it is present. Larvae come in black and in brown forms and often feed on Epilobium (fireweed). 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. Tersa sphinx (Xylophanes tersa) USGS Non-resident; present only as an adult moth fall stray
