Brown County, Wisconsin
Sphingidae

Thirty Sphingidae species are listed in the USGS for Wisconsin. Not all of the species are reported (two by USGS: Achemon sphinx, Eumorpha achemon and Bedstraw hawkmoth, Hyles gallii) or anticipated (twenty-seven by Bill Oehlke) in Brown County.

This page is inspired by and dedicated to Joan Tadisch of Green Bay, Wisconsin. Joan sent me the images of the White-lined Sphinx caterpillar at the top and bottom of this page.

Joan reports, "I ran across your web site when I was trying to identify a caterpillar found in my yard in Green Bay, Wisconsin. Two photos of the caterpillar are attached. The photos are of the same caterpillar and were taken on July 27, 2004. The plant it is on in the photo is the plant I found it on. I think it is a Joe-pye weed but am not sure. The caterpillar has red feet."

Larvae of this species can be quite variable as you will see by visiting the species file below. the caterpillar in Joan's photos was probably green a day or two earlier. Many Sphingidae larvae darken as they prepare to descend foliage to pupate under leaf litter or even under ground.

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 Polk 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.

Sphinginae subfamily Sphingini tribe: Agrius cingulata, WO Pink-spotted hawkmoth, very rare 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 quinquemaculata WO, the Five-spotted Hawkmoth This large bodied moth flies in tobacco fields and vegetable gardens (potatoes, tomatoes) and wherever host plants are found. probably present Sphinx canadensis WO, Sphinx canadensis, the Canadian Sphinx, is not common, and is not often reported anywhere, and may be present in Brown 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 possibly in Brown 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 not reported in Brown County, but it is likely present. 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. probably present 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 Sheboygan 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 USGS, 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. more southerly 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 a bit unlikely. Deidamia inscriptum WO, the Lettered Sphinx This species has not been recorded in Brown. It is seen in southern Ontario, however, and in central and southern Wisconsin and might be present. Hyles gallii USGS, the Bedstraw Hawk Moth or Gallium Sphinx This species is reported in Brown County. Some years I see them on P.E.I., some years, I do not. Hyles lineata JT, 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. Hyles lineata larva, July 27, 2004, Green Bay, Joan Tadisch 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.

Sphingidae larvae can be quite variable. I will try to identify any large larvae you encounter in Wisconsin. An image always helps, via email to Bill Oehlke.

Enjoy some of nature's wonderments: Saturniidae cocoons. Cocoons of these giant silkmoths are for sale in fall and winter. Large, beautiful moths emerge in the spring and summer.
