Chittenden County, Vermont
Sphingidae Larvae

This page is dedicated to Elizabeth Finstad who provides the image of a heavily parasitized Paonias excaecata larva at the top of the page.

Elizabeth writes, "I found your website while searching for what kind of parasite might have done this to this pretty caterpillar. I have been trying to find large moth caterpillars for years, and, of course, the first time I do find one it is diseased! I'm not sure what kind of moth it is, but I'm leaning, toward either one-eyed sphinx or poplar sphinx.

"It is almost 2" long, kind of a lime green color with the same color horn. The head is triangular looking.

"There are white egg-like things near its head, and brown spots all over its back. They do not resemble the braconid wasp eggs that I see when searching for what might be wrong with it, but I'm not sure if these are holes that remain after the wasps have hatched.

"I live in Milton, VT and found it in the Niquette Bay State Park near my house this morning. Let me know, if you have time, what kind of caterpillar it might be and if you have seen one look like this before."

I reply, "Thanks for thinking of me. Your larva is that of Paonias excaecata, the Blinded Sphinx.

"I request permission to post one or two of the images to my Chittenden County page at http://www.silkmoths.bizland.com/vtChittendensphlar.htm.

"You are correct, the larva has been parasitized. The darker wounds on the back are from emergent parasitoids. The white eggs closer to the head appear to be fresh eggs of another parasitoid.

Elizabeth writes, "Thanks for getting back to me! The poor thing died last night. You have my permission to use the images. I've never seen the actual moth before."

Visit Chittenden County, Vermont, Adult Sphingidae.

Visit Vermont Catocala, (Underwing Moths).

Seventeen Sphingidae species are listed for Vermont on the BAMONA website. I have added many species based on James P. Tuttle's excellent new book, The Hawk Moths of North America. Not all of the species are reported or anticipated or "considerabled possible" (thirty-two by Bill Oehlke) in your county.

It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the caterpillars (larvae) 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 moth is present or might be present.

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.

Please also send sightings to BAMONA, an excellent online resource, via the link to the left.

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 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 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). Manduca quinquemaculatus 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. 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 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 WO, 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 WO, the Modest Sphinx or Poplar Sphinx The anal horn is very rudimantary in final inistar. It is fond of poplars and willows. Paonias excaecata WO/EF, the Blinded Sphinx Larvae accept willows, birches, and cherries. I have also found them in the wild on oak in eastern Canada. Paonias excaecata fifth instar larva, Niquette Bay State Park, Milton, September 14, 2012, Elizabeth Finstad 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: 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 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 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 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. questionable, generally more southerly 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 (ovals can be orange on green forms). There are orangey-brown and green forms also. 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 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 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. Proserpinus flavosfasciata WO, Yellow-banded Day Sphinx: Penultimate instar is pale green with pair of pale, dorsolateral lines running from head to base of short caudal horn. Last instar is brown-black with numerous black dots; caudal horn replaced by a black button surrounded by whitish band edged with black. 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.
