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. unlikely
|
|
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). |
|
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. |
|
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.
|
|
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.
|
|
This caterpillar is also without the anal horn and feeds on pines.
The long stripes and reddish brown afford great camouflage.
|
|
Note triangular bump on the thorax.
Larval hosts are various species of beebalm (Monarda), mints (Mentha), bugleweed (Lycopis),
and sage (Salvia).
|
|
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.
|
|
Note the red horn and black dots anterior to the white oblique lines.
If you grow tomatoes, you have probably encountered it.
|
| 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).
|
|
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.
|
|
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.
|
|
Larvae feed exclusively on various species of ash (Fraxinus).
Raised, pointed bumps, especially near the head and thorax give this
caterpillar a reptilian appearance. unlikely
|
|
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).
|
|
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 larvae feed upon Walnut and butternut (Juglans),
hickory (Carya), alder (Alnus), beech (Fagus),
hazelnut (Corylus), and hop-hornbeam (Ostrya).
|
|
Blueberry and huckleberry (Vaccinium), cherries (Prunus) and
willows (Salix) are the favorites as larval foodplants.
|
|
|
Larvae accept willows, birches, and cherries.
I have also found them in the wild on oak in eastern Canada.
|
|
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.
|
|
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 two species.
|
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:
|
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.
|
|
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:
|
In additon to Virginia creeper larvae accept Grape (Vitis),
ampelopsis (Ampelopsis), and cayenne pepper (Capsicum).
Larvae are green until the final instar.
|
|
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
USGS, 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.
|
|
Larvae feed on Smooth hydrangea (Hydrangea arborescens),
buttonbush (Cephalanthus occidentalis), and waterwillow
(Decodon verticillatus).
Note small head which can be retracted into the thorax.
|
|
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.
|
|
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
The snake-like larva has a head and the three thoracic segments which may be retracted into abdominal segment 1, which is swollen and adorned with a pair of
light-ringed eye-spots. I often get questions about these larvae due to their voracious appetites for garden penta species.
