I know that the particular horn often denotes a species as being in Sphingidae, but I haven't seen one with this specific pattern before. Tried looking it up using an ID tool that uses traits of the insect and it gave me "Hyles galli" but comparing it to all the other pictures of larvae I'm not confident in that answer. I still have it and could potentially wait for the adult to emerge, but I figured it would be good to post here as well.
