Rock County, Wisconsin
Sphingidae

Thirty Sphingidae species are listed in the USGS for Wisconsin. Not all of the species are reported (none by USGS as of August 2009, n.b.: not intended as a criticism; I use the USGS site regularly) or anticipated (thirty-three by Bill Oehlke) in Rock County.

This page is dedicated to and inspired by Scott Smith who has sent the Eumorpha pandorus image top of the page from Rock County.

Scott writes, "Here's a shot I thought you might like for your collection. Not the greatest background, but a beautiful specimen none the less. My family had a garage sale Saturday and looked at this all day thinking it was a shriveled up leaf. Then I happened to sit right next to it... and to my surprise! Enjoy!"

It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the moths you have encountered.

A WO" after the species name indicates that I have no confirmed reports of this species in Rock 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 image, via email to Bill Oehlke.

Many thanks to Chris Frelich who provides the following image of Hemaris thysbe:

Sphinginae subfamily Sphingini tribe: Agrius cingulata, WO Pink-spotted hawkmoth, stray This species is a strong migrant and adults nectar from deep-throated flowers including moonflower (Calonyction aculeatum), morning glory (Convolvulus), honey suckle (Lonicera) and petunia (Petunia species). Might be present as a rare stray. Ceratomia amyntor WO, 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 catalpae WO, the Catalpa Sphinx The upperside of the forewing is yellowish brown with no white markings, but there are indistinct black lines and dashes. The cell spot is gray with a black outline. The larvae feed in large groups and are much more spectacular than the moths. Catalpa is the larval host. Ceratomia hageni WO, Hagen's Sphinx or Osage Orange Sphinx The upperside of the forewing is gray with a green tint and has dark indistinct wavy lines, and pale gray patches at the wing tip and along the costa. 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. 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 WO, 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. If you have pines, you probably have this species. It also flies on P.E.I. generally more northerly Lintneria eremitus WO, the Hermit Sphinx Generally this species is not widely reported. Larval hosts are various species of beebalm (Monarda), mints (Mentha), bugleweed (Lycopis), and sage (Salvia). Manduca quinquemaculatus WO, the Five-spotted Hawkmoth This large bodied moth flies in tobacco fields and vegetable gardens (potatoes, tomatoes) and wherever host plants are found. possibility Manduca sexta WO, the Carolina Sphinx This species is now recorded in Gloucester by Jesse Donovan. If you grow tomatoes, you have probably encountered it, though. Larvae get very large and can strip a tomato plant. only in southern Wisconsin Sphinx canadensis WO, Sphinx canadensis, the Canadian Sphinx, is not common, and is not often reported anywhere, but it has been seen in Sheboygan County. Larval hosts are white ash (Fraxinus americana) and blueberry (Vaccinium). 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. Sphinx drupiferarum WO, the Wild Cherry Sphinx Forewings, long and slender, are held close to the body when the moth is at rest. Larvae are beautiful and feed on cherry foliage. Sphinx gordius WO, the Apple Sphinx The upperside of the forewing ranges from brown with black borders through brownish gray with paler borders to pale gray with no borders. Dashes, submarginal line, and cell spot are usually weak. 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 luscitiosa WO, the Canadian Sphinx or Clemen's Sphinx: The fw upperside is yellowish gray in males and pale gray with faint yellow tint in females (left). The dark border on the outer margin widens as it approaches inner margin. Hw upperside is deep yellow in males, pale yellow in females with wide black border. Sphinx poecila WO, the Poecila Sphinx If you have blueberries in the woods, then you probably have the Poecila Sphinx. They are probably widespread throughout Wisconsin, but are very much under reported. generally more northerly 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 large poplar/willow feeder is probably found in Walworth County. They are a heavy bodied species. Paonias excaecata WO, the Blinded Sphinx, The outer margin of the forewing is quite wavy. There is a dark cell spot and a dark oblique line mid wing from the costa almost to the inner margin. Basic ground colour is pinkish brown. Flight would be June-July. Paonias myops WO, the Small-eyed Sphinx This small species is not confirmed by USGS, but I suspect it is present. This species ranges across North America. The hindwings have a small blue eyespot ringed with black on a yellow background. Smerinthus cerisyi WO, the Cerisyi's Sphinx or One-eyed Sphinx, The fw outer margin is more irregular than in S. jamaicensis. Larvae feed on poplars and willows. Flight would be from early May-July as a single brood. 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. Macroglossinae subfamily Dilophonotini Tribe: See Hemaris comparison to help distinguish the next three species. Hemaris diffinis WO, the Snowberry Clearwing or Bumblebee Moth, The moth flies along forest edges and in meadows, gardens and brushy fields. Day-flying adults nectar at lantana, dwarf bush honeysuckle, snowberry, orange hawkweed, thistles, lilac, Canada violet, etc. Hemaris gracilis WO, The Slender Clearwing or Graceful Clearwing This day flier is not commonly reported, but it might be present in Columbia County. Generally it is reported more to the east. unlikely Hemaris thysbe WO/CF, the Hummingbird Clearwing It is not difficult to see why many gardeners would mistake an Hemaris thysbe moth for a small hummingbird as it hovers, sipping nectar from flowers through a long feeding tube. Hemaris thysbe, Janesville, August 29, 2012, Chris Frelich Philampelini Tribe: Eumorpha achemon WO, the Achemon Sphinx Adults nectar from flowers of Japanese honeysuckle (Lonicera japonica), petunia (Petunia hybrida), mock orange (Philadelphus coronarius), and phlox (Phlox). Note the differences between this moth and the Pandorus Sphinx. Eumorpha pandorus SS, 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. Eumorpha pandorus, Evansville, August 1, 2009, Scott Smith Macroglossini Tribe: Amphion floridensis WO, the Nessus Sphinix This day flier is widely distributed. If you have Virginia Creeper, you might have the Nessus Sphinx. Two bright, distinct, narrow yellow bands are often visible on the abdomen. Darapsa choerilus WO, 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 myron WO, the Virginia Creeper Sphinx or the Grapevine Sphinx It is widely reported in southern Michigan and in southern Ontario. It may be present, although unlikely. Darapsa versicolor WO, the Hydrangea Sphinx If you have hydrangea growing near a stream, then you may have the Hydrangea Sphinx. It has not been reported in Walworth, but is likely there. Deidamia inscriptum WO, the Lettered Sphinx. The forewing outer margin of this early spring flier is deeply scalloped. The upperside is light brown with dark brown markings and a small black and white spot near wing tip. The upperside of the hindwing is orange-brown with a dark brown outer margin and median line. Males rest with a strong curve to the abdomen. Hyles gallii WO, the Bedstraw Hawk Moth or Gallium Sphinx This species is not reported in Columbia, but it has been recorded in eastern Wisconsin counties. I suspect it is present. Some years I see them on P.E.I., some years, I do not. Hyles lineata WO, the White-lined Sphinx Adults usually fly at dusk, during the night, and at dawn, but they also fly during the day over a wide variety of open habitats including deserts, suburbs, and gardens. Sphecodina abbottii WO, the Abbott's Sphinx This moth is very much under reported on USGS. It is a rapid day flier so is probably not in too many collections. Grape is a popular larval host.
