Dione juno (Juno Heliconian) is a species of butterflies in the family brush-footed butterflies. They visit flowers of lantana, passionflower, and Baccharis latifolia. Unlike other Heliconian species, the Silver-Spotted Flambeau does not feed on pollen. The adults fly quickly and erratically. They prefer open, sunny areas, and may be found up to 2500 m in altitude. Mature caterpillars are black and covered in orange spots and black spines.
