Diaethria candrena

Diaethria candrena, the candrena eighty-eight or number eighty, is a species of butterfly of the family Nymphalidae. It is found in Argentina and Brazil.

The wingspan is 40–46 mm. The forewings are black with a deep blue basal flush. The hindwings are mostly black, again with a deep blue basal flush. The underside of the forewing is mostly red with a broad black border. The underside of the hindwing is mostly white with a thin black outer margin and two thin black concentric bands bordering a distinct "80" design on the centre of the wing, hence one of the common names.

The larvae feed on Celtis species.
