Eumorpha phorbas is a moth of the Sphingidae family. It is known from Ecuador, Surinam, Bolivia, Guatemala, Nicaragua, Costa Rica, Belize and Mexico.The wingspan is 112–116 mm. It is similar to Eumorpha labruscae labruscae in the largely green upperside of the body and forewings, but can be distinguished by the lacking blue patches on the hindwing upperside, instead showing essentially the same pattern of orange and dark brown as in Eumorpha capronnieri.
