Biology

Adults are on wing from April to July in one generation in the north and in two generations in the south.

The larvae feed on Vitis, Ampelopsis, and Capsicum species.

Taxonomy

It was first described as Sphinx nessus by Pieter Cramer in 1777. This name was invalid, because Dru Drury had already used it for another species (Theretra nessus) in 1773. A replacement name was published in Benjamin Preston Clark in 1920.
