Hemeroplanes ornatus is a species of sphinx moth native from Mexico through northern South America.

[2] H. ornatus is mainly light brownish gray with green, pink, and dark brown markings.

The caterpillar is green, camouflaged against its host plant Fischeria panamensis.

[2][4] However, when disturbed, the caterpillar hangs from the vine with his prolegs and puffs up its head and thorax.

The underside of its body is brown, and it has a pair of false eyes on the thorax, making it look like a small snake.
