Thirty Sphingidae species are listed in the USGS (Now BAMONA) for Wisconsin. Not all of the species are reported (three by USGS; three by Lep. Soc. Season Summary) or anticipated (twenty-seven by Bill Oehlke) in Chippewa County.

This page is inspired by and dedicated to Lance Johnson who found a Sphinx chersis larva on July 13, 2007, in Chippewa Falls.

Lance writes, "I picked up a hawk moth larvae today and was attempting to determine exactly what it is.

"It may be a Sphinx chersis?

"Would you be able to assist if I sent some images of the actual larvae?"

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 Chippewa 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.

Please also submit all sightings to BAMONA, an excellent online resource.

Many thanks to Eric Wymore who sends the following image of a Ceratomia amyntor larva from the Lake Holcombe area. His three young sons found it by their sandbox.

Unfortunately, as is the case with many found larvae, this caterpillar has been heavily parasitized as indicated by the grey, blotchy, circular areas on its skin. These "wounds/scars" are indicative of parasitoid entry or exit points, and this larvae will never become a moth.

I do very much appreciate the submission from Eric and sons, as it confirms Ceratomia amyntor breeding populations in Chippewa County.

Sphinginae subfamily Sphingini tribe: Ceratomia amyntor WO/EW, 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 amyntor fifth instar, Lake Holcombe, Wisconsin, August 31, 2012, Eric Wymore family. Ceratomia undulosa 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. Dolba hyloeus WO, 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 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. Manduca quinquemaculata WO, 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). Sphinx canadensis WO, Sphinx canadensis, the Canadian Sphinx, is not common, and is not often reported anywhere, but it might be present in Chippewa County. Larval hosts are white ash (Fraxinus americana) and blueberry (Vaccinium). Sphinx chersis LJ, 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. Lance Johnson reports a larva find, July 13, 2007. Sphinx kalmiae WO, 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 poecila WO, the Poecila Sphinx If you have blueberries in the woods, then you probably have the Poecila Sphinx. They are probably widespread throughout Wisconsin, but are very much under reported. 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 WO, 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. generally more eastern species Paonias myops WO, 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 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". Smerinthus jamaicensis WO, 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 diffinis WO, 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 WO, the Slender Clearwing or Graceful Clearwing Larval foods are blueberries including low bush blueberry (Vaccinium vacillans), and laurel (Kalmia), all in the heath family (Ericaceae). 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. generally more eastern species 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. Eumorpha pandorus WO, 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. unlikely 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. Deidamia inscriptum WO, 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 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 WO/KD, 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.
