Sphingidae Larval Checklist
El Dorado County, California

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

Thirty-two Sphingidae species are listed in the USGS for California. Not all of the species are reported by USGS (now BAMONA) or anticipated in El Dorado County. Six species are reported on BAMONA.

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

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 BAMONA indicates the moth is reported on the BAMONA website and/or in Moths of Western North America, #2. Distribution of Sphingidae of Western North America, revised, 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 image, via email to Bill Oehlke.

Please also forward your sightings to BAMONA, an excellent online resource.

Sphinginae subfamily

Sphingini tribe:

Manduca quinquemaculatus WO, the Five-spotted Hawkmoth

The caterpillars are called Tomato Hornworms and each has a black horn at the end of the abdomen. Larvae feed on potato, tobacco, tomato, and other plants in the nightshade family (Solanaceae). There is also a very beautiful brown form. See bottom of page.

Manduca sexta WO, the Carolina Sphinx

Tobacco Hornworms, equipped with a red-tipped horn at the end of the abdomen, are true gluttons and feed on tobacco and tomato, and occasionally potato and pepper crops and other plants in the nightshade family (Solanaceae).

Sphinx chersis WO, the Great Ash Sphinx

The larvae are pale bluish green. The head has a pair of yellow lateral bands meeting at the apex.

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 perelegans BAMONA, the Elegant Sphinx; A unique feature of this larva is a shield on the first thoracic segment, which is of the same colour as the body and which forms a tight-fitting hood over the vertex of the head. This hides a pair of glossy black spots on top of the head, which are revealed if the animal is disturbed.

Sphinx sequoiae BAMONA, the Sequoiae Sphinx:

Larvae feed on California juniper (Juniperus californica) and Rocky Mountain juniper (J. osteosperma).

Sphinx vashti BAMONA, the Snowberry Sphinx

Larvae feed on the common snowberry (Symphoricarpos albus) and on coralberry (S. orbiculatus).

Note the two golden lines of slightly raised bumps, one just behind the head, the other on the thorax.

Smerinthini Tribe:

Pachysphinx occidentalis WO, the Big Poplar Sphinx

Larvae feed on cottonwood and poplar (Populus) and willow (Salix).

Larvae are very chunky with little to distinguish them from Pachysphinx modesta.

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.

Skin is quite granulous.

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 cerisyi BAMONA, Cerisy's Sphinx; Cerisyi larvae greatly resemble modesta larvae, both being pale green, with granular skin, pale lateral diagonal lines, faint red spiracular circles, and very pale longitudinal lines running from the head to a more pronounced anal diagonal line. Larvae have green heads bounded dorsally with a pale yellow inverted "V".

Macroglossinae subfamily


Dilophonotini Tribe:

Hemaris thetis BAMONA,

Larval host plants include Snowberry (Symphoricarpos), honeysuckle (Lonicera), Coralberry, viburnums, high bush cranberry and hawthorn (Crataegus).

Horn is black with a slightly lighter base. This western species was formerly classified as H. diffinis or H. senta. Those species west of the Continental Divide are now classified as H. thetis.

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.

Macroglossini Tribe:

Arctonotus lucidus WO, the Pacific Green Sphinx Moth or Bear Sphinx

Larvae feed on evening primrose (Oenothera dentata var. campestris) and clarkias. David Wikle fed them on both Mexican evening primrose, Oenothera berlandieri and evening primrose, Oenothera biennis.

Hyles euphorbiae WO ??, Leafy Spurge Hawk Moth Larvae feed on leafy spurge. Larvae are also conspicuously colored, with a pronounced tail or "horn" near rear end. Young larvae are variously patterned with green, yellow, and black; older larvae have distinctive red, black, yellow, and white color pattern. Mature larvae may approach 10 cm in length; when disturbed, they regurgitate a slimy green liquid.

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.

Proserpinus clarkiae BAMONA, Clark's Sphinx,

Larvae feed on elegant fairyfan (Clarkia unguiculata) in the evening primrose family (Onagraceae).
