Fond du Lac County, Wisconsin
Sphingidae

Thirty Sphingidae species are listed in the USGS (now BAMONA for Wisconsin. Not all of the species are reported (none by BAMONA as of July 23, 2012) or anticipated (twenty-seven by Bill Oehlke) in Fond du Lac County.

This page is inspired by and dedicated to Larry Lewis who sent me the image of the White-lined Sphinx at the top of the page.

Larry writes, (after I had identified a larva of this species for him), "Here's the picture of the moth. Had four on the bushes at once."

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 Fond du Lac 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.

Please also send your sightings to BAMONA, an excellent on-line, resource.

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). 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 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. 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. 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 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 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 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. 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. 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 probably in your county. This species ranges across North America. The hindwings have a small blue eyespot ringed with black on a yellow background. Pachysphinx modesta WO, the Modest Sphinx or Poplar Sphinx, This large poplar/willow feeder is reported in nearby Sheboygan County. They are a heavy bodied species. Smerinthus cerisyi WO, the Cerisyi's Sphinx or One-eyed Sphinx, Larvae feed on poplars and willows. Flight would be from late May-July as a single brood. This one is very questionable. 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 your county. Generally it is reported more to the east. unlikely Hemaris thysbe WO, 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. 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 WO, 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. 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. Deidamia inscriptum WO, the Lettered Sphinx This species has not been recorded in Fond du Lac. It is seen in southern Ontario, however, and in central and southern Wisconsin and might be present. Hyles gallii WO, the Bedstraw Hawk Moth or Gallium Sphinx This species is not reported in Fond du Lac, but it has been recorded in other eastern Wisconsin counties. I suspect it is present. Some years I see them on P.E.I., some years, I do not. Hyles lineata LL, 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.
