Taylor County, Wisconsin
Sphingidae

Thirty Sphingidae species are listed in the USGS for Wisconsin. Not all of the species are reported (none by USGS) or anticipated (twenty-seven by Bill Oehlke) in Taylor County.

This page is inspired by and dedicated to Joan F. Rickert who lives near Medford in Taylor County, Wisconsin. Joan sent me sighting data for Sphinx chersis and also sent the larval images of Ceratomia undulosa, top and bottom of this page, as well as other sightings indicated by JFR.

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 Taylor County, but I (William Oehlke) expect that this moth is 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:

Ceratomia amyntor WO, the Elm Sphinx or Four-horned Sphinx

This moth is not recorded in Taylor County, but I suspect it is present.

Larvae feed on Elm (Ulmus), birch (Betula), basswood (Tilia), and cherry (Prunus).

Ceratomia undulosa JFR/WO, the Waved Sphinx

This moth is now recorded in Taylor County, courtesy of Joan F. Rickert.

It is named for the wavy lines on the forewings.

Lapara bombycoides WO, the Northern Pine Sphinx

This species is not officially reported from Taylor.

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.

Sphinx canadensis WO, Sphinx canadensis, the Canadian Sphinx, is not common, and is not often reported anywhere, but it might possibly be present in Taylor County.

Larval hosts are white ash (Fraxinus americana) and blueberry (Vaccinium).

Sphinx chersis JFR/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 eremitus JR, the Hermit Sphinx

This species is confirmed for Taylor County by Joan F. Rickert. Generally it is not widely reported.

Larval hosts are various species of beebalm (Monarda), mints (Mentha), bugleweed (Lycopis), and sage (Salvia).

Sphinx kalmiae WO/JFR, the Laurel Sphinx

This species is not reported in Taylor County, but it should be present. I have taken them on P.E.I., Canada, and reared them on lilac.

At rest the hindwings are usually completely covered.

Sphinx luscitiosa WO, the Canadian Sphinx or Clemen's Sphinx

This one is not reported from Taylor, but it may be present. Sphinx luscitiosa adults fly as a single brood from June-July.

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

This moth is not reporterd in Taylor County but may be present.

This is the first Sphinx species I reared as a boy in New Jersey. 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 Taylor County. This species ranges across North America.

The hindwings have a small blue eyespot ringed with black on a yellow background.

Pachysphinx modesta JFR/WO, the Modest Sphinx or Poplar Sphinx,

This large poplar/willow feeder is now reported in Taylor County, courtesy of Joan F. Rickert

They are a heavy bodied species.

Smerinthus cerisyi WO/JFR, 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.

Smerinthus cerisyi, May 31, 2006, Joan F. Rickert

Smerinthus jamaicensis WO/JFR, the Twin-spotted Sphinx

This moth is widely distributed and fairly common, although it is not officially recorded in Taylor County.

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/ JFR, 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 Taylor County. unlikely

Hemaris thysbe WO/JFR, the Hummingbird Clearwing

This interesting day flier is now confirmed for Taylor, courtesy of Joan F. Rickert.
They are widely distributed in the east from P.E.I. to Florida.

Philampelini Tribe:

Eumorpha achemon WO, the Achemon Sphinx

This moth is not reported for Taylor, but it may be present.

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 JFR/WO, the Nessus Sphinix

This day flier is widely distributed. 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, 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.
Taylor County may be just slightly northwest of the identified range.

Darapsa myron WO, the Virginia Creeper Sphinx or the Grapevine Sphinx
This moth is not recorded on the U.S.G.S. site for Taylor County. 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 Taylor.

It is seen in southern Ontario, however, and in central and southern Wisconsin.

Hyles gallii WO, the Bedstraw Hawk Moth or Gallium Sphinx

This species is not reported in Taylor, 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 JFR/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.
