About Eumorpha achemon Drury, 1773
Eumorpha achemon, first described by Drury in 1773, has a wingspan ranging from 87 to 97 mm. It can be told apart from all other species in the Eumorpha genus by the appearance of its hindwing upperside: this area is almost uniformly pale pink from the base up to a diffuse, dark brown submarginal band. Its larvae occur in three distinct color forms: light green, reddish orange, and tan to brown. This species is native to North America. Across the continent, it can be found across most of the United States, in southern Canada, and in northern Mexico. It is rare or entirely absent from the Pacific Northwest, the Great Basin, and the majority of the Southeastern United States, with Florida being the only exception.
