WO, Separated Sphinx. Salvia greggii has been confirmed as a 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."
Tomato Hornworms: each has a black horn at the end of abdomen.
Potato, tobacco, tomato, and other plants in the

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

little leaf ash (Fraxinus gooddingii) in Oleaceae
family. Green and dark forms; larvae tend to darken just before pupation.
Big Poplar Sphinx.
Larvae feed on cottonwood and poplar (Populus) and willow
Larvae are very chunky with little to distinguish them
from Pachysphinx modesta.
Wild cherry species are the favorites as larval
foodplants, but eggs will also be deposited on birches and other
forest trees. To the left a second/third instar larva rests on pin
cherry. The "red heart" marking readily identifies this species.
generally more eastern species; possibly
Cerisy's Sphinx; Greatly resemble modesta larvae, both pale
green, with 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".
Sphinx, flies in valleys and along streamsides from Mexico City north
