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

This page is inspired by and dedicated to Kara, who provides the Lintneria eremitus image top of this page.

Kara writes, ``I am writing about the caterpillar that I have had in my possession for the past several weeks, which I finally was able to i.d. through one of your pages.

``He was discovered accidentally on a cut bunch of basil that was in a water filled vase on my kitchen counter. He was exactly the same color as the leaf, and really small (less than an inch long, and slender). I put him in a jar, with his own supply of basil, and continued to watch him change, which was fascinating. I tried in vain to find him on the internet, with his two distinctive horns ... but no luck. He started to develop diagonal bands, pale at first. When he slowed down his massive appetite one day, I was concerned for him (I have no experience raising these lovely creatures!), and monitored him more closely. In the morning, he had morphed into a totally new worm! No longer the bright green, but a tawny brown color that seemed to change in texture by the hour. The black spot that formed on his head was spectacular! No longer did he have a horn there, and the horn in the rear was yellow at first, with a thin black line at the center. Eventually, it was all black. He grew to an enormous size, and eschewed any other type of leaf that I put in there. Basil was on the menu in perpetuity.

``I am writing now because I just i.d.'d him from the aforementioned site yesterday, and he has taken a new turn.. interestingly... yesterday. He stopped eating, and has been circling the open weave 'critter cage' that I moved him into a couple of weeks ago. I put several layers of torn paper toweling in the bottom (as I saw suggested for pupating) and he moved around under those, but gave up on that idea and is looking smaller (did he shrink!?!?) and forlorn on the plastic bottom of this container. His head looks a bit lighter in colour, other than the black spot. He definitely lost some mass and length since yesterday. I wanted to rear him to the moth stage, but I certainly don't want him to expire on my watch! Can you give me some advice? I sure would appreciate it! Thanks.

``p.s. I was going to take a picture of him, but he has now crawled underneath the paper toweling, between the plastic bottom and the first piece of towel.``

I replied, ``Yes, It is Lintneria eremitus. Shrinkage is typical just prior to pupation. It will probably settle shortly and pupate within three to five days.``

Twenty Sphingidae species are listed for Maryland on the U.S.G.S. website as of August 2007. Not all of the species are reported or anticipated in Carroll County (none are reported on U.S.G.S. as of August 2010). It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the caterpillars you are likely to encounter.

A "WO" after the species name indicates that I (William Oehlke) expect that this species is present or might be present. I have added quite a few species to the Maryland list.

A "USGS" indicates the moth is reported on the USGS website and/or 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.

Ceratomia amyntor WO, the Elm Sphinx or Four-horned Sphinx
Caterpillars show both brown and green forms and are unmistakeable due to four horns on the thorax (near the head).

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

Ceratomia catalpae WO, the Catalpa Sphinx

This caterpillar is one of the few North American Sphingidae that feed in large groups. Colouration is distinctive.

The larvae are much more spectacular than the moths. Catalpa is the larval host.

Ceratomia undulosa WO, the Waved Sphinx

Note the pinkish-orange tail, spiracles outlined in red and the cream stripes on the head.
The dramatic color change from the dorsal yellow-green to the lateral light greyish-blue is not always as intense as in this image.

Dolba hyloeus WO, the Pawpaw Sphinx

Note the smooth skin, blue-black horn and small black spiracles.
Pawpaw is the primary host. Littleleaf sweetfern, possum haw, inkberry, tall gallberry holly and others are also utilized.

Lapara bombycoides WO, generally more westerly, the Northern Pine Sphinx

This caterpillar is also without the anal horn and feeds on pines.

The long stripes and reddish brown afford great camouflage.

Lapara coniferarum WO, the Southern Pine Sphinx

This caterpillar is also without the anal horn and feeds on pines.

The long stripes and reddish brown afford great camouflage.

Lintneria eremitus Kara, the Hermit Sphinx

Note triangular bump on the thorax.

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

Manduca jasminearum WO, the Ash Sphinx

Larvae feed on ash in the Fraxinus genus. Syringa and Ulmus have also been reported.

Note the black anal horn.

Manduca quinquemaculatus WO, the Five-spotted Hawkmoth
Note the solid black horn and dark spiracular rings. In addition to the white oblique lines, there are fainter white rings, especially on the back.

I suspect if you grow tomatoes, you are likely to encounter it.

Manduca sexta WO, the Carolina Sphinx

Note the red horn and black dots anterior to the white oblique lines.

If you grow tomatoes, you have probably encountered it.

Paratrea plebeja WO, the Plebeian Sphinx

Larvae feed at night, hiding on the underside of stems during the day. Preferred hosts are common trumpetcreeper (Campsis radicans), Florida yellow-trumpet (Tecoma stans), lilac (Syringa species), and passionflower (Passiflora species). Questionable

Sphinx chersis WO, the Northern Ash Sphinx or Great Ash Sphinx

Note pale blue horn and the creamy-white stripes on head. The yellow form has a red horn. Larval hosts are ash, lilac, privet, cherry and quaking aspen.

Sphinx drupiferarum WO, the Wild Cherry Sphinx

Larvae hide in the day and feed primarily on cherry, plum, and apple at night. Larvae have been found on Amelanchier nantuckensis in Massachusetts and have been reared to pupation in Michigan on Prunus serotina. Note purple oblique lines.

Sphinx franckii WO, Franck's Sphinx Moth

Larvae feed exclusively on various species of ash (Fraxinus).

Raised, pointed bumps, especially near the head and thorax give this caterpillar a reptilian appearance.

Sphinx gordius WO, the Apple Sphinx

Larval hosts are apple (Malus), sweetfern (Myrica), Carolina rose (Rosa carolina), blueberry and huckleberry (Vaccinium), white spruce (Picea glauca), American larch (Larix laricina), and alder (Alnus).

Sphinx kalmiae WO, the Laurel Sphinx

In the final instar, the black on the head, lateral lines, horn and on abdominal legs is diagnostic.

Larvae feed primarily on lilac and fringe.

Smerinthini Tribe:

Amorpha juglandis WO, the Walnut Sphinx

Amorpha juglandis larvae feed upon Walnut and butternut (Juglans), hickory (Carya), alder (Alnus), beech (Fagus), hazelnut (Corylus), and hop-hornbeam (Ostrya).

Pachysphinx modesta WO, generally more westerly; unlikely, the Modest Sphinx or Poplar Sphinx
This moth is not officially recorded in Carroll County. It is fond of poplars and willows.

Paonias astylus WO, the Huckleberry Sphinx

Blueberry and huckleberry (Vaccinium), cherries (Prunus) and willows (Salix) are the favorites as larval foodplants.

Paonias excaecata WO, the Blinded Sphinx

Larvae accept willows, birches, and cherries. I have also found them in the wild on oak in eastern Canada.

Paonias myops WO, the Small-eyed Sphinx

Wild cherry species are the favorites as larval foodplants, but eggs will also be deposited on birches and other forest trees.

There are varying degrees in the amount of red markings along the sides.

Smerinthus jamaicensis WO, the Twin-spotted Sphinx

Larvae feed upon many forest trees including birches and cherries, but are expecially fond of poplars and willows. Red markings on sides vary greatly from specimen to specimen.

Macroglossinae subfamily


Dilophonotini tribe:

See Hemaris comparison to help distinguish the next three species.

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.

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 gracilis WO, the Slender Clearwing or Graceful Clearwing
Hemaris gracilis is distinguished from similar species by a pair of red-brown bands on the undersides of the thorax, which varies from green to yellow-green dorsally and sometimes brown with white underneath. They have a red abdomen.

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 fasciatus WO, unlikely, the Banded Sphinx

Larvae feed upon primrose-willow, Ludwigia (water primrose) and other plants in the evening primrose family (Onagraceae). Grape family members also serve as larval hosts. generally further south

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.

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 lineata WO, 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.

Xylophanes tersa WO, the Tersa Sphinx

Larvae feed on Borreria, Catalpa and Manettia spp. and Smooth buttonplant (Spermacoce glabra) and starclusters (Pentas species). They are also recorded on joe-pie weed and Hamelia patens and on Hedoydis nigricans. The green form may be more common. generally more southerly and easterly
