Sphinx drupiferarum WO, Wild Cherry Sphinx:
Hide in day, feed primarily on cherry, plum, apple at night, on Amelanchier nantuckensis
in Massachusetts; in Michigan on Prunus serotina. Note purple oblique lines.
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.
Amorpha juglandis larvae feed upon Walnut and butternut (Juglans),
hickory (Carya), alder (Alnus), beech (Fagus),
hazelnut (Corylus), and hop-hornbeam (Ostrya).
the Modest Sphinx or Poplar Sphinx
This moth is not officially recorded in Bucks County. It is fond
of poplars and
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.
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
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.
See Hemaris comparison to help distinguish
the next three species.
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.
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.
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. unlikely
Larvae feed upon Grape (Vitis), Virginia Creeper
(Parthenocissus quinquefolia) and other vines and ivies
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
Note the five large white ovals. There are orangey-brown and green
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.
WO, the Virginia Creeper Sphinx or the
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
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.
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
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.
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
