Omegaw County, northern Michigan
Sphingidae Larvae

This page is inspired by and dedicated to Cindy Mead of Omegaw County, Michigan. Cindy has sent me many Catocala images, as well as the image of Pachysphinx modesta at top of this page.

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

Forty-six Sphingidae species are listed in the USGS (now BAMONA) for Michigan. Not all of the species are reported (three are listed by BAMONA as of August 19, 2012) or anticipated (twenty-eight by Bill Oehlke) in Ogemaw County. Some of the species reported by BAMONA occur in Michigan as fall strays from further south. The strays do not reproduce in Michigan, so you would not encounter their 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 Ogemaw 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 send your sightings to BAMONA, an excellent on-line resource.

Sphinginae subfamily Sphingini tribe: Ceratomia amyntor WO, 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 undulosa BAMONA, 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. 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. 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). Lintneria eremitus fifth instar, August 28, 2012, Cindy Mead Manduca quinquemaculatus 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. 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: 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 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 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 luscitiosa WO, 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 might 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 CM, the Modest Sphinx or Poplar Sphinx Larvae feed on poplars and cottonwood. Anal horn all but disappears in final instar. Paonias excaecata WO, the Blinded Sphinx Larval skin is grainy in appearance. 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 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: Hemaris diffinis BAMONA, 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. 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: 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. not common 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. questionable as larva, northern range limit Hyles gallii PB, the Bedstraw Hawk Moth or Gallium Sphinx: Larvae come in black and in brown forms and often feed on Epilobium (fireweed). Hyles gallii, Fife Lake, September 11, 2008, Patty Burwell. 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.
