Death head hawk moth

Notes:

This species is similar to the European A. atropos but differs in having two medial bands on the underside of the forewing, instead of one, and usually no dark bands across the ventral surface of the abdomen. The skull-like marking is darker and there is a faint blue tornal dot enclosed by a black submarginal band on the hindwing upperside. The forewing discal spot (stigma) is orange; in A. atropos it is usually white. There are two described subspecies, A. s. styx, and A. s. medusa Moore, but they intergrade widely, and authorities presently consider that A. s. medusa is just a wet zone/season form, and not taxonomically distinct.
