Description
The wingspan is 99–119 mm for males and 103–130 mm for females. It is similar to Eumorpha anchemolus, but the forewing upperside pattern is more contrasting and variegated. There is a prominent discal spot found on the greenish buff basal area of the hindwing upperside.

The larvae feed on Saurauia montana and Cissus rhombifolia, as well as Actinidiaceae species. They have a well-developed anal horn in the first instar, becoming less prominent as the larvae develop.
