Washington County, Rhode Island

This page is dedicated to Ryan Saint Laurent who sent me the beautiful image of a very fresh Hemaris thysbe moth from Washington County, Rhode Island.

Ryan found the larva during the late summer/early fall of 2007. He successfully overwintered the pupa and took this image before the moth had flown.

In August of 2009 Ryan sent me the beautiful image of a Ceratomia amyntor larvae that he found on birch. It is linked below the amyntor thumbnail and from the amyntor page.

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 Newport 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.

Ceratomia amyntor, North Kingstown, Washington County, Rhode Island,
July 6, 2011, as submitted by Sue Bozeman for identification for photographer FF Julin.

Sphinginae subfamily Sphingini tribe: Agrius cingulata WO stray This species would only be enountered in Newport County as a stray from much further south. The moth is a very strong flier and is frequently encountered far north of its usual range. Ceratomia amyntor WO/RSL/FF Julin, the Elm Sphinx or Four-horned Sphinx The upperside of the forewing is brown with dark brown and white markings including a white costal area near the wing base, dark streaks along the veins, and a white spot in the cell. Larvae feed on Elm (Ulmus), birch (Betula), basswood (Tilia), and cherry (Prunus). Ceratomia amyntor larva, August 27, 2009, Ryan Saint Laurent. Ceratomia amyntor, North Kingstown, July 6, 2011, FF Julin Ceratomia catalpae WO, the Catalpa Sphinx This is generally a more southerly species, but it may be present in Newport County near Catalpa Trees. I saw them in great numbers in New Jersey. The larvae feed in large groups and are much more spectacular than the moths. Catalpa is the larval host. Ceratomia undulosa WO, the Waved Sphinx The upperside of the forewing is pale brownish gray with wavy black and white lines and a black-outlined white cell spot. The upperside of the hindwing is gray with diffuse darker bands. Dolba hyloeus WO, the Pawpaw Sphinx The upperside of the forewing is dark brown with a dusting of white scales. Some moths have patches of reddish or yellowish brown on the wings. Larve are not limited to pawpaw. Lapara bombycoides USGS, the Northern Pine Sphinx The upperside of the forewing is gray with heavy black bands. The upperside of the hindwing is brownish gray with no markings. Lapara coniferarum USGS, the Southern Pine Sphinx The upperside is of the forewing is gray with two (sometimes one or three) black dashes near the wing center; other markings are usually diffuse. The upperside of the hindwing is a uniform brown-gray. Lintneria eremitus WO, the Hermit Sphinx The upperside of the forewing is gray-brown with wavy lines, black dashes, and one or two small white spots near the center of the costa. Manduca jasminearum WO the Ash Sphinx This species is not recorded in Newport County and usually is not found north of Connecticut. This moth is a strong flier and may occasionally stray into Rhode Island. Manduca quinquemaculatus WO the Five-spotted Hawkmoth The moth abdomen usually has five but sometimes six pairs of yellow bands. The upperside of the forewing is blurry brown and gray. I suspect if you grow tomatoes you have encountered it. Manduca rustica WO, the Rustic Sphinx Look for three large yellow spots on each side of the abdomen. The upperside of the forewing is yellowish brown to deep chocolate brown with a dusting of white scales and zigzagged black and white lines.unlikely stray Manduca sexta WO, the Carolina Sphinx This species is recorded in Newport County. If you grow tomatoes, you have probably encountered it. Larvae get very large and can strip a tomato plant. Paratrea plebeja WO, the Plebian Sphinx The upperside of the forewing is gray with indistinct black and white markings. There is a series of black dashes from the base to the tip, and a small white cell spot. Sphinx chersis WO, the Northern Ash Sphinx or Great Ash Sphinx The upperside of the forewing is soft dark gray to blue-gray with a series of black dashes, one of which reaches the wing tip. Larval hosts are ash, lilac, privet, cherry, and quaking aspen. Sphinx drupiferarum USGS, the Wild Cherry Sphinx Sphinx drupiferarum larvae hide in the day and feed primarily on cherry, plum, and apple at night. Larvae have been found on Amelanchier nantuckensis in Massachusetts. Sphinx gordius USGS, the Apple Sphinx This species is present in Newport County. Colouration and markings are highly variable from one specimen to another. The fringes on forewing are mostly black with some white; those on the hindwing are mostly white with a few black patches. Sphinx kalmiae WO, the Laurel Sphinx The lower forewings are predominantly brownish-yellow with a fairly wide dark bar along the inner margin. At rest the wings hug the body, giving the moth a long slender look. Sphinx poecila USGS, the Poecila Sphinx If you have blueberries in the woods, then you probably have the Poecila Sphinx. They are pretty common here on Prince Edward Island, but don't fly too far south of Massachusetts, being replaced by Sphinx gordius in Connecticut. Smerinthini Tribe: Amorpha juglandis WO, the Walnut Sphinx The adults are also highly variable; sometimes wings of an individual may be all one color or may have several colors, ranging from pale to dark brown, and may have a white or pink tinge. See the file for the female; she is different. Pachysphinx modesta WO, the Modest Sphinx or Poplar Sphinx This moth is not officially reported from Newport County, but it may be present. They are common on Prince Edward Island. 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 Named for the dull grey-blue spot in the hindwing, this moth has a wide distribution and is probably common in Newport County. I regularly see them on Prince Edward Island, and they are reported as far south as Florida. Paonias excaecata found as larvae, summers of 2007 and 2008, Ryan St. Laurent. Paonias myops WORSL, the Small-eyed Sphinx Named for the small eye-spot in the hindwing, this moth has a wide distribution and is probably common in Washington County. I regularly see them on Prince Edward Island, and they are reported as far south as Florida. Smerinthus cerisyi WO, the Cerisyi's Sphinx Smerinthus cerisyi is found in the southern regions of all Canadian provinces and in northern border states. The one-eyed sphinx is also found along the U.S. west coast, eastward to the Rockies. At my home in Montague, P.E.I., Canada, they are quite common. Smerinthus jamaicensis WO, the Twin-spotted Sphinx Smerinthus jamaicensis closely resembles Smerinthus cerisyi, but jamaicensis is much smaller with larger blue patches on more vibrant and deeper purple in the lower wings. Along the East Coast, it flies from P.E.I. to Florida. Macroglossinae subfamily Dilophonotini tribe: See Hemaris comparison to help distinguish the next three species. Hemaris diffinis WO, the Snowberry Clearwing or Bumblebee Moth Adults mimic bumblebees and are quite variable, both geographically and seasonally. The wings are basically clear, with dark brown to brownish-orange veins, bases and edges. Hemaris gracilis WO, The Slender Clearwing or Graceful Clearwing This day flier is not commonly reported, but is probably present in Newport. Hemaris thysbe RSL, the Hummingbird Clearwing This interesting day flier is confirmed for Newport. They are widely distributed in the east from P.E.I. to Florida. Philampelini tribe: Eumorpha achemon USGS, the Achemon Sphinx This moth is not reported for Newport, but it is fairly often reported along the coast from southern New Jersey to central Maine. Note the differences between this moth and the Pandorus Sphinx. Eumorpha pandorus USGS, the Pandorus Sphinx If you have Grape or Virginia Creeper nearby, then you probably have this species. I often get asked to identify larvae from areas where they have not previously been reported. Macroglossini tribe: Amphion floridensis WO , the Nessus Sphinix This day flier is widely distributed although not officially recorded in Newport County. If you have Virginia Creeper, you probably have the Nessus Sphinx. Two bright, distinct, narrow yellow bands are often visible on the abdomen. Darapsa choerilus WO/RSL, the Azalea Sphinx They are common in New Jersey and common here on Prince Edward Island. You will often see this species listed as Darapsa pholus, especially in older literature. Darapsa choerilus larva on Viburnum, September 10, 2009, Ryan Saint Laurent. Darapsa myron WO, the Virginia Creeper Sphinx or the Grapevine Sphinx This moth is not recorded on the USGS site for Newport County. It is widely reported as far north as southern Maine. If you have the foodplants indicated in the common names, you probably have this species nearby. Darapsa versicolor WO, the Hydrangea Sphinx If you have hydrangea growing near a stream, then you may have the Hydrnagea Sphinx. It has not been widely reported, however, and probably is uncommon. Deidamia inscriptum RSL , the Lettered Sphinx The moth's outer margin of the forewing is deeply scalloped. The upperside is light brown with dark brown markings. There is a small black and white spot near the tip. The upperside of the hindwing is orange-brown with a dark brown outer margin and median line. Deidamia inscriptum, June 1, 2008, Ryan St. Laurent Hyles gallii WO , the Bedstraw Hawk Moth or Gallium Sphinx This species is reported in nearby counties. Some years I see them on P.E.I., some years, I do not. Hyles lineata WO/RSL, the White-lined Sphinx It is a strong migrator from the south, and there are records from the west and to the north. Hyles lineata larva, September 10, 2009, Ryan Saint Laurent Sphecodina abbottii WO , the Abbott's Sphinx This moth is very much under reported. It is a rapid day flier so is probably not in too many collections. Grape is a popular larval host. Xylophanes tersa WO , the Tersa Sphinx The upperside of the forewing is pale brown with lavender-gray at the base and has dark brown lengthwise lines throughout. The upperside of the hindwing is dark brown with a band of whitish, wedge-shaped marks. only as a possible stray
