Henry County, Illinois
Sphingidae Larvae

For care of "found larvae/caterpillars" visit Manduca sexta larva, central Texas, August 21, 2008, Trina Woodall.

Forty-two Sphingidae species are listed in the USGS for Illinois. Not all of the species are reported (five species by USGS as of August 17, 2010) or anticipated (twenty-seven by Bill Oehlke) in Henry County.

This page is inspired by and dedicated to Rita Dakin and her grandson Ryan Linden.

Rita writes, "My grandson found a caterpillar that matches the coffee can lid photo in the info on your web page.

"It has just gone into the pupa stage and we would like to know if it will now overwinter here in Illinois, USA, or hatch sooner.

"Thank you for any information you can give us."

I replied, "Usually they only produce a single brood each year, so I suspect it will overwinter, but I cannot be sure. Some of the Sphingidae produce more than one brood each year. If you took a picture of the caterpillar, please send it along as a jpg attachment." ......

"With the arrival of the picture, I can confirm it is Pachysphinx modesta. They are thought to be single brooded in northern parts of their range, with a possible second brood from Missouri south. The prepupal purplish colouration of your larva suggest it is going to overwinter. Had your grandson found it a few days earlier, it would have been green and likely still feeding on foliage."

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

A WO" after the species name indicates that I have no confirmed reports of this species in Cook County, but I (William Oehlke) expect that this species 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.

Please also forward your results to BAMONA, an excellent on-line resource.

Macroglossinae subfamily


Dilophonotini Tribe:

Hemaris diffinis WO, the Snowberry Clearwing or Bumblebee Moth
Larval host plants include Snowberry (Symphoricarpos), honeysuckle (Lonicera), Coralberry, viburnums, Blue Dogbane (Apocynum) and dwarf bush honeysuckle (Diervilla lonicera). Horn is black with a yellow base.

Hemaris thysbe WO, the Hummingbird Clearwing

There is also an orangey-pink prepupal form. The lateral line runs from S1 to the blue horn.

Hemaris thysbe larvae feed on viburnum and related plants.

Philampelini Tribe:

Eumorpha achemon WO, the Achemon Sphinx

Larvae feed upon Grape (Vitis), Virginia Creeper (Parthenocissus quinquefolia) and other vines and ivies (Ampelopsis).

Larvae occur in both a light (green) form and a darker (tan/brown) form. Note six "segmented" oblique lines.

Eumorpha pandorus WO, the Pandorus Sphinx

If you have Grape or Virginia Creeper nearby, then you might encounter this species.

Note the five large white ovals. There are orangey-brown and green forms also.

Macroglossini Tribe:

Amphion floridensis WO, the Nessus Sphinix

In additon to Virginia creeper larvae accept Grape (Vitis), ampelopsis (Ampelopsis), and cayenne pepper (Capsicum).

Larvae are green until the final instar.

Darapsa choerilus WO, the Azalea Sphinx

Larvae feed on Azalea and Viburnum and progress very rapidly. The larva to the left on Viburnum cassinoides is getting ready to pupate. Color change from green to light burgundy-brown indicates pupation is imminent.

Darapsa myron WO, the Virginia Creeper Sphinx or the Grapevine Sphinx

If you have the foodplants indicated in the common names, you probably have this species nearby. The lower wings are orange. Larvae feed on Virginia creeper (Parthenocissus quinquefolia), Grape (Vitis), Ampelopsis, and Viburnum.

Darapsa versicolor WO, the Hydrangea Sphinx

Larvae feed on Smooth hydrangea (Hydrangea arborescens), buttonbush (Cephalanthus occidentalis), and waterwillow (Decodon verticillatus).

Note small head which can be retracted into the thorax. rare

Deidamia inscriptum WO, the Lettered Sphinx

Grape (Vitis), ampelopsis (Ampelopsis), and Virginia creeper (Parthenocissus) all serve as larval hosts.

The alternating yellow and greyish-green rings across the back distinguish this larva.

Hyles gallii WO, the Bedstraw Hawk Moth or Gallium Sphinx

This species is not reported in Chippewa, but it has been recorded in eastern Wisconsin counties. I suspect it is present.
Larvae come in black and in brown forms and often feed on Epilobium (fireweed). questionable

Hyles lineata USGS, the White-lined Sphinx

Larvae are highly varied and feed on a great diversity of plants including willow weed (Epilobium), four o'clock (Mirabilis), apple (Malus), evening primrose (Oenothera), elm (Ulmus), grape (Vitis), tomato (Lycopersicon), purslane (Portulaca), and Fuschia.
All larvae seem, however, to have the red/black swellings split by dorso-lateral lines.

Sphecodina abbottii WO, the Abbott's Sphinx

Larvae feed at night on grape (Vitis) and ampelopsis (Ampelopsis) and hide on the bark of their host plants during the day. Virginia creeper would also be a suitable host.

There is also a dark form without the green patches. Note the "raised eye", replacing the anal horn.
