A widespread neotropical genus.
A widespread neotropical genus. The butterflies in this genus are recognized by the orange upperside, reflective silver spots on the underside, and the shape of the antennal club (DeVries, 1997).
The hostplants are all members of the Passifloraceae. Dione is able to utilize a great number of species and subgroups of Passiflora. The eggs are laid in large groups on old leaves, and the larvae can be agricultural pests in passion flower farms. The larvae are almost unicolored, spiny and gregarious feeders. The pupae are not spined, and in general are dull and cryptic (DeVries, 1997) (see each species for more details).
Etymology: DIONE was the goddess of the oracle of Dodona in Thesprotia, and the mother of Aphrodite by Zeus. Her name is simply the feminine form of Zeus (Dios) (DIONE).
