Abbott’s Sphinx Caterpillar

Dear Lauren,
This is a Caterpillar of an Abbott’s Sphinx Moth,
Sphecodina abbottii, and you can verify that by comparing your individual to this image posted to BugGuide.  According to BugGuide:  “Larvae start out green with a horn on the final segment. Middle instar larvae are whitish to blue-green with dark faint cross-stripes and the horn replaced by an orange raised knob on the last segment (A8). The last instars may be either brown with a “wood-grain” pattern or brown with ten pale green saddles along the back. In these late instars the knob resembles an eye.”
