Sphinginae subfamily
Sphingini tribe:
 |
Ceratomia amyntor, Elm Sphinx, Four-horned Sphinx:

due to four horns on the thorax (near the head).
Larvae feed on Elm (Ulmus), birch (Betula), basswood (Tilia), and
cherry (Prunus).
|
 |
Ceratomia catalpae, Catalpa Sphinx; (Steuben):
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.
|
 |
Ceratomia hageni, Hagen's Sphinx, Osage Orange Sphinx; (Steuben):

along the oblique white stripes.
|
 |
Ceratomia undulosa, Waved Sphinx:

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.
|
 |
Dolba hyloeus, Pawpaw Sphinx:
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.

Larval hosts are various species of beebalm (Monarda), mints (Mentha), bugleweed (Lycopis),
and sage (Salvia).

 |
Manduca quinquemaculatus, Five-spotted Hawkmoth (Allen)é(Steuben):

I suspect if you grow tomatoes, you are likely to encounter it.

Manduca sexta, Carolina Sphinx; (Steuben): Note the red horn and black dots anterior to the white oblique
lines. If you grow tomatoes, you have probably encountered it.

caterpillar a reptilian appearance.

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.

are usually as per the upper image.
Possibly present as a very rare adult stray, unlikely to be seen in larva stage.
