Washingon County, Rhode Island

This page is dedicated to Ryan Saint Laurent who sent me the Paonias excaecata larval image at top of page.

Ryan has also reported finds of Hemaris thysbe larvae and an adult Deidamia inscriptum June 1, 2008.

Ryan writes, "Today (June 1st) I found a female (pretty sure it was female) lettered sphinx adult resting on tall grass not far from my house. May have recently eclosed because of its good condition. I brought it home and photographed it, then sat it on a tree. There is a lot of grape around my house so maybe I'll come across some larvae later this year. I'll go back out tonight probably to see if there is a male. This would be my first sphinx of the year, and my first Lettered Sphinx in Washington County, RI."

In August of 2009, Ryan sent a beautiful image of a Ceratomia amyntor larva that he found feeding on birch. Click on the link below the amyntor thumbnail.

Ryan confirms Darapsa choerilus (image and data via link below) and Hyles lineata.

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

Eleven Sphingidae species are listed for Rhode Island on the U.S.G.S. website. Not all of the species are reported or anticipated in Washington County (eight are reported on U.S.G.S.: Northern pine sphinx (Lapara bombycoides), Southern pine sphinx (Lapara coniferarum), Blinded sphinx (Paonias excaecata), Wild cherry sphinx (Sphinx drupiferarum), Apple sphinx (Sphinx gordius), Poecila sphinx (Sphinx poecila), Achemon sphinx (Eumorpha achemon) and Pandorus sphinx (Eumorpha pandorus).

I have added many species to the list which I feel are likely present.

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 your county, but I (William Oehlke) expect that this moth is present or or might be present. I have added many species.

A USGS indicates the moth is reported in the USGS 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.

on Pinus strobus, September 12, 2010, courtesy of Ryan St. Laurent.

Sphinginae subfamily Sphingini tribe: Ceratomia amyntor WO/RSL, 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 larva (green form), August 27, 31, 2009, Ryan Saint Laurent. 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. Ceratomia undulosa WO, 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). Louis Handfield reports larvae probably feed on Ilex verticellata in Quebec. 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. Look for greenish true legs on bombycoides and orangey ones on coniferarum. Lapara bombycoides larva on Pinus strobus; September 12, 2010 Lapara coniferarum USGS, the Southern Pine Sphinx Larvae feed upon various pine species, including loblolly pine (Pinus taeda) and longleaf pine (P. pinaster). They are well camouflaged and are without an anal horn. Look for greenish true legs on bombycoides and orangey ones on coniferarum. 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 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 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). Manduca sexta WO/RSL, 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). Manduca sexta on tomato plant, Washington County, Rhode Island, September 1, 2009, Ryan Saint Laurent. 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. 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 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. Sphinx gordius USGS, 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 The larval skin is much smoother in the final instar, having lost the grainy appearance evident in the fourth instar. Sphinx poecila USGS, the Poecila Sphinx If you have blueberries in the woods, then you probably have the Poecila Sphinx. Most often the larvae are green in final instar. Only a few show the purple form. 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 astylus WO, the Huckleberry Sphinx Paonias astylus, the Huckleberry Sphinx (wingspan 55-65 mm), ranges from Maine south to Florida, west to Missouri and Mississippi. Paonias excaecata RSL/USGS, the Blinded Sphinx Larvae accept willows, birches, and cherries. I have also found them in the wild on oak in eastern Canada. The skin is very granulose. Paonias excaecata, 2007 and 2008, Ryan St. Laurent. Paonias myops WO, the Small-eyed Sphinx The larvae depicted is probably third instar. There may be more red spotting on the sides as larvae mature. 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 thysbe RSL, 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 thysbe, 2007 , Ryan St. Laurent. 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). 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 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/RSL, 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 choerilus September 10, 2009, Ryan Saint Laurent. 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 turn a deep chocolate brown just prior to pupation, and the "horn" on the tail also turns downward as pupation draws near. Darapsa versicolor larvae feed on Smooth hydrangea (Hydrangea arborescens), buttonbush (Cephalanthus occidentalis), and waterwillow (Decodon verticillatus). Deidamia inscriptum RSL, 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. Deidamia inscriptum adult female, June 1, 2008 , Ryan St. Laurent. 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/RSL, 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. Hyles lineata, September 10, 2009, Ryan Saint Laurent 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.
