Windsor County

Sphingidae

This page, inspired by Beth Anderson, is dedicated to Beth for sending me sighting data for an Hyles gallii caterpillar (August 21, 2006, Chester (near the Williams river), Windsor County, Vermont).

Beth writes, " I saw one of these caterpillars yesterday (Aug 21) evening while out for a walk with my husband in Chester (near the Williams river). It was crossing the road. My husband told me not to touch (because of the sticker on its rear end), but I got it on to a large leaf and put it on the side of the road. It seemed aggressive for a caterpillar. It looked very similar to the caterpillar picture on your site only more reddish-brown, it had a dusty pink belly, and it was about 2 – 2 1\2 inches. I’ve been looking all over the web to find out what it was. I wish we had a camera."

The "horn" at the tail end of Sphingidae larvae looks menacing, but it is harmless. It is always best to proceed with caution, however, as some hairy caterpillars and some spiny ones can give a nasty sting.

Seventeen Sphingidae species are listed for Vermont on the U.S.G.S. website. All of those species are reported in Windsor. I have, however, added some species which I feel are probably present in Vermont (not reported) and in Windsor County. 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. A "USGS" indicates the moth is reported 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.

Sphinginae subfamily

Sphingini tribe:

Ceratomia amyntor USGS, 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 USGS, 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.

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.

Manduca quinquemaculata USGS 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.

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 USGS, the Wild Cherry Sphinx

TForewings, long and slender, are held close to the body when the moth is at rest.

Sphinx eremitus USGS, 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. The upperside of the hindwing is black with two white bands and a triangular black patch at the base. Note the golden hair on the thorax.

Sphinx kalmiae USGS, 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 upperside of the forewing is yellowish gray in males and pale gray with a faint yellow tint in females. In both sexes, the dark border on the outer margin widens as it approaches the inner margin.

Sphinx poecila WO, 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 in eastern Canada. They are reported as far south as northeastern New York.

Smerinthini Tribe:

Amorpha juglandis USGS, 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 USGS, the Modest Sphinx or Poplar Sphinx

This moth has a large, heavy body, and females can be remarkably plump.

They are common on Prince Edward Island.

Paonias excaecata WO, the Blinded Sphinx

Named for the dull grey-blue spot in the hindwing, this moth has a wide distribution and is probably common in Windsor although not officially recorded.

I regularly see them on Prince Edward Island, and they are reported as far south as Florida.

Paonias myops WO, the Small-eyed Sphinx

Named for the small eye-spot in the hindwing, this moth has a wide distribution and is probably common in Windsor although not reported.

I regularly see them on Prince Edward Island, and they are reported as far south as Florida.

Smerinthus cerisyi USGS, the Cerisyi's Sphinx

Smerinthus cerisyi antennae typically rest alongside head and thorax and forewings generally conceal hindwings. This is a very easy species to rear.

Smerinthus jamaicensis USGS, 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:

Hemaris thysbe USGS, 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 diffinis USGS, 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. The abdomen tends to be dark (black) with 1-2 yellow segments just before the terminal end.

Philampelini tribe:

Eumorpha achemon USGS, the Achemon Sphinx

This moth has beautiful pink hindwings.

Larvae get quite large and are often found on grape foliage or crawling on the ground seeking some soft earth for tunneling and pupation.

Macroglossini tribe:

Amphion floridensis USGS, 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. I suspect they are present.

Darapsa myron USGS, the Virginia Creeper Sphinx or the Grapevine Sphinx
This moth is recorded on the U.S.G.S. site for Windsor 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:
Fw upperside is often greenish brown with curved dark lines and pinkish-white patches. Hw upperside is pale yellow to reddish brown with white along the costal margin, greenish brown along the outer margin, and white shaded with greenish brown on inner margin.

Hyles gallii BA/USGS, the Bedstraw Hawk Moth or Gallium Sphinx

This species is reported in Windsor County by Beth Anderson.

Some years I see them on P.E.I., some years, I do not.

Hyles lineata WO, the White-lined Sphinx

This species is not reported from Windsor County. It is a strong migrator from the south, and has been seen in northern New Hampshire.

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.
