Agrius cingulata, Pink-spotted hawkmoth.
Plants in the Convolvulaceae family, especially
Ipomoea batatas (sweet potato); in Solanaceae family,
especially (Datura) (jimsonweed); related plants. Also a brown form. Look for very large, dark
Ceratomia amyntor, Elm Sphinx; Four-horned Sphinx.
Larvae feed on Elm (Ulmus), birch (Betula), basswood
(Tilia), and cherry (Prunus).
There are both green and brown forms. The four horns near
the head are diagnostic.
Lintneria istar, Istar Sphinx. Larvae feed primarily on mints (Salvia).
Larvae can be considerably darker as per the image at top of the page.
I think istar, separatus and smithi are all being reassigned to the Lintneria genus.
Lintneria separatus, Separated Sphinx. Salvia greggii has been confirmed as larval host
by Robert A. Behrstock. Jim Tuttle, tentative id, writes, "All of the penultimate instars of both Lintneria (Sphinx) istar and
Lintneria (Sphinx) separatus that I have reared have been mundane green."
the Five-spotted Hawkmoth.
Tomato Hornworm: black horn at the end of the abdomen.
Larvae feed on potato, tobacco, tomato, other plants in nightshade family (Solanaceae). Very beautiful brown form.
Manduca quinquemaculatus, Five-spotted Hawkmoth. Tomato Hornworm: black horn at end of abdomen.
Larvae feed on potato, tobacco, tomato, and other plants in the nightshade family (Solanaceae). There is also a very beautiful brown form to the left.
Manduca rustica, Rustic Sphinx.
Numerous white nodules on top of thorax;
seven pairs of oblique, blue-gray stripes along side of body.
Horn white at base, blue-gray at tip. Many hosts are utilized.
Manduca sexta, Carolina Sphinx>
Tobacco Hornworms, equipped with red-tipped horn at end of abdomen; true gluttons, feed on tobacco and tomato, and
occasionally potato, pepper crops, other plants in nightshade family (Solanaceae).
Sagenosoma elsa, Elsa Sphinx.
Larval hosts are unknown, but larvae probably feed on Lycium
in the nightshade family (Solanaceae). Note the strong oblique black lines and the black anal horn.
Sphinx asellus, Asella Sphinx.
Larval hosts are Manzanita and Arctostaphylos of Ericaceae family. Note purple on both sides of oblique white lines, pale
blue horn, brown head, purple feet.
Sphinx chersis, Great Ash Sphinx.
Pale bluish green. Head has pair of yellow lateral bands meeting at apex.
Larval hosts: ash, lilac, privet, cherry, quaking aspen.
Sphinx dollii, Doll's sphinx. Larval hosts: Alligator juniper (Juniperus deppeana),
other juniper species. It is amazing to me how well the larval spiracular patches and false feet match the pattern and colour of the juniper bark.
Sphinx libocedrus, Incense Cedar Sphinx. Larvae feed on New Mexican forestiera
(Forestiera neomexicana), on Forestiera angustifolia and on little leaf ash (Fraxinus gooddingii) in the Oleaceae
family. Green and dark forms and all larvae tend to darken just before pupation.
Sphinx vashti, Snowberry Sphinx.
Larvae feed on common snowberry (Symphoricarpos albus)
and on coralberry (S. orbiculatus). Note two golden lines of slightly raised bumps, one just behind head, other on thorax.
Pachysphinx occidentalis, 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, Blinded Sphinx.
Larvae accept willows, birches, and cherries.
I have also found them in the wild on oak in eastern Canada.
Larval skin is rough and grainy.
Paonias myops, Small-eyed Sphinx.
Wild cherry species are the favorites as larval foodplants, but eggs will also be deposited on birches and other
To the left a second/third instar larva rests on pin cherry. The "red heart" marking readily identifies this species.
Smerinthus cerisyi, Cerisy's Sphinx;
Greatly resemble modesta larvae: pale green, granular skin, pale lateral diagonal lines, faint red
spiracular circles, very pale longitudinal lines running from head to more pronounced anal diagonal line.
Green heads bounded dorsally with pale yellow inverted V.
Erinnyis obscura, Obscure Sphinx.
Rauvolfia ligustrina, Rauvolfia tetraphylla, Stemmadenia obovata, Philibertia, Cynanchum, papaya
(Carica papaya), Asclepiadaceae, Blepharodon mucronatum,
White vine (Sarcostemma clausum), Morrenia odorata.
Hemaris diffinis, Snowberry Clearwing; Bumblebee Moth.
Snowberry (Symphoricarpos), honeysuckle (Lonicera), Coralberry, viburnums, Blue Dogbane
(Apocynum), dwarf bush honeysuckle (Diervilla lonicera).
Horn black; yellow base. East of Great Divide.
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 specimens west of the Continental Divide are now classified as
Eumorpha achemon, 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.
Darapsa myron WO, Virginia Creeper Sphinx; 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.
Euproserpinus wiesti, Wiest's Primrose Sphinx:
Day flyer over sand washes, prairie blow-outs as single brood from May-June. Prairie primrose (Oenothera latifolia) in evening
primrose family (Onagraceae).
Captive rearing difficult. Larvae need sunshine, heat, humidity.
Hyles lineata, White-lined Sphinx.
Highly varied; feed on 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), Fuschia. All larvae seem, however, to have red/black swellings split by dorso-lateral lines.
Proserpinus juanita, Juanita Sphinx.
(Onagraceae) including evening primrose (Oenothera), gaura (Gaura), and willow weed
(Epilobium). Early instars are green and lack the dark sharply contrasting spiracular circles and other patterning.
Proserpinus vega, Vega sphinx.
Larvae probably feed on (Onagraceae) including evening primrose (Oenothera), gaura (Gaura), and willow weed (Epilobium).
