Description
Memphis pithyusa is a butterfly with a wingspan of 57 mm to 76 mm, with forewings with a concave outer edge and hindwings with a tail. The upper part is dark blue to brown, with a lighter basal part, blue or blue-green, and a submarginal line of light dots.The underside is light brown and simulates a dead leaf. It is the smallest form of this group. It differs from the similar species chiefly by the shape; distal margin and proximal margin of the forewings are much less deeply sinuous, so that the inner angle does not project so much; the apex of the forewings likewise decreases in intensity thereby. The female [not in errore] is, according to Druce, much larger than the female, the base of the wings is bluer and the spots on the forewings are larger and mostly white. In many places common.
