Protambulyx eurycles

Description

Protambulyx eurycles is a species of moth of the family Sphingidae first described by Gottlieb August Wilhelm Herrich-Schäffer in 1854. It is known from Suriname, Guyana, French Guiana, Colombia, Ecuador, Peru, Bolivia, Brazil, Costa Rica, Nicaragua and Mexico. It is similar to Protambulyx euryalus but the forewing marginal band is much broader and the proximal edge is crenulated. Females are less heavily marked than males. There are probably multiple generations per year. Adults have been recorded in March, August and October in Bolivia and in September in Brazil. The larvae probably feed on Anacardiaceae species.
