Saratoga County, New York
Sphingidae: Larval Thumbnails

This page is inspired by and dedicated to Matt Pelikan who sent me the image of the parasitized Hyles gallii larva at the top of this page.

Matt writes, "While visiting Saratoga National Historic Park yesterday, my wife and I found a splended caterpillar, perhaps two inches long, jet black, with a row of round yellow spots like portholes down each side and a red tail-horn. I've tentatively ID'd it as Hyles gallii, the likely foodplant for which, bedstraws, were abundant in the area (at least two species). I've read that this caterpillar is usually brown or green but grows very dark prior to pupating. Is this is a plausible ID? Would be happy to send the photo around."

I reply, "I would like to see photos, and post them with credit to you? Hyles gallii would certainly be in that area, and description and foodplant match."

Matt indicates, "If the photo would be of use on your site, you're very welcome to it. Unfortunately it's not on a natural substrate, so it's not a very attractive shot.

"When I got home and had access to my field guides, I found a photo and account in David Wagner's book that look exactly right (including a penchant in late instars for walking around on pavement). And the abundance of bedstraws nearby was really pronounced, something I had commented on just before we found the caterpillar."

"Many thanks, Matt. It is indeed Hyles gallii. This one is heavily parasitized. You can see the white parasitoid eggs, at least seven of them on the first abdominal and thoracic segments. Many found larva suffer a similar fate, and no moth would develop from this larva."

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

Forty-six Sphingidae species are listed for New York on the U.S.G.S. website. Not all of the species are reported or anticipated in Saratoga County (five are reported on U.S.G.S. as of September 28, 2010). It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the moths you are likely to encounter.

A "WO" after the species name indicates that I have no confirmed reports of this species in Saratoga County, but I (William Oehlke) expect that this moth is present. A "USGS" indicates the moth is reported on the USGS website and/or in Lepidoptera of North America, #1. Distribution of Silkmoths (Saturniidae) and Hawkmoths (Sphingidae) of Eastern North America, an excellent little booklet available through Paul Opler.

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.

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 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. 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. Manduca sexta WO, 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 WO, 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 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 (sometimes greenish), creamy-white stripes on head. Lateral stripes are often not as developed as shown. Thoracic segments have small white nodules. Yellow form has red horn. Larval hosts: ash, lilac, privet, cherry, 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 This one is reported from Richmond and from northeastern New Jersey into southern Canada. 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 USGS, the Modest Sphinx or Poplar Sphinx This moth is officially recorded in Delaware County. It is fond of poplars and willows. Paonias excaecata WO, 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 cerisyi USGS, 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 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. 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 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 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 MP/USGS, the Bedstraw Hawk Moth or Gallium Sphinx Larvae come in black and in brown forms and often feed on Epilobium (fireweed). Hyles gallii, parasitized fifth instar, Saratoga National Historical Park, September 26, 2010, Matt Pelikan. 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: Fourth instar: pale green with pair of pale, dorsolateral lines running from head to base of short caudal horn. Last instar: brown-black with numerous black dots; caudal horn replaced by 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.
