White-Lined Sphinx

Adult sphinx moths have protruding heads, large eyes, a large “furry” thorax, and a conical abdomen that extends well beyond the hindwings when the moth flies. On this species, the top of the long forewing is dark olive brown with a narrow tan band running from the base of the wing to the tip and with light tan streaks along the veins. Larvae vary; bright yellow-green or bluish-black with rows of whitish to yellow spots or dots and veinlike tracings. The caudal horn, which looks something like a tail, is yellowish green or black.
