Sphinginae subfamily
Sphingini tribe:
 |
Larvae feed on plants in the Convolvulaceae family, especially
Ipomoea batatas (sweet potato) and in the Solanaceae family,
especially (Datura) (jimsonweed) and related plants in the
Americas. There is also a brown form. Look for very large, dark
spiracular circles. stray
|
|
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.
|
 |
Note the green horn, raised white bumps and strong dark lines
anterior to the white ones.

Manduca sexta
USGS/JC, 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).
|
 |
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.
|
 | Larval hosts are Alligator juniper (Juniperus deppeana)
and 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.
|
 | Larvae feed on New Mexican forestiera
(Forestiera neomexicana), on Forestiera angustifolia
and on little leaf ash (Fraxinus gooddingii) in the Oleaceae
family. There are green and dark forms and all larvae tend to darken
just before pupation.

 |
Sphinx perelegans
USGS, 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.
|
 |
Larvae feed on California juniper (Juniperus californica) and Rocky Mountain juniper (J. osteosperma).
|
 |
Sphinx vashti
USGS,
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.
generally more northerly
|
Smerinthini Tribe:
 |
Larvae feed on cottonwood and poplar (Populus) and willow
(Salix).
Larvae are very chunky with little to distinguish them
from Pachysphinx modesta.
|
 |
Smerinthus cerisyi
USGS,
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:
 |
This species is more likely to occur as an occasional stray rather than as a breeding resident.
As a migrant stray it would be seen later in the season, July-August.
|
 |
Larvae feed on papaya (Carica papaya), Cnidoscolus
angustidens, poinsettia (Euphorbia pulcherrima),
guava (Psidium species) and
saffron plum (Bumelia angustifolia/Bumelia celastrina).
Manilkara bahamensis,
Willow Bustic (Bumelia salicifolia)
and Painted Leaf (Poinsettia heterophylla) are also hosts.
Nice socks! Larvae show considerable variation.
|
 |
Erinnyis obscura, the Obscure Sphinx, USGS
Larvae probably feed on various plants in the dogbane family
(Apocynaceae): Rauvolfia ligustrina, Rauvolfia tetraphylla,
Stemmadenia obovata, Philibertia, Cynanchum, and on papaya
(Carica papaya, Caricaceae), and Asclepiadaceae.
|
 |
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:
 |
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
USGS, the Banded Sphinx
Larvae feed upon primrose-willow, Ludwigia (water primrose)
and other plants in the evening primrose family. This hornless larva is
highly variable. Look for large, dark spiracular circles and a dark
line in the center of the back. See image at bottom of this page.
|
Macroglossini Tribe:
 |
Arctonotus lucidus
USGS, the Pacific Green
Sphinx Moth or Bear SphinxLarvae 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. |
 |
Young caterpillars eat flowers, while older caterpillars eat flowers
and new leaves. Larvae feed on Camissonia contorta epilobioides in
the primrose family (Onagraceae).
This species is listed as "threatened" in its known range. |
 |
Larvae feed on various plants in the primrose family (Onagraceae).
|
 |
Hyles lineata
BDM/,font color=green>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. |
 |
Larvae feed on elegant fairyfan (Clarkia unguiculata) in the evening primrose family (Onagraceae). |
