Dione junoMargarita Beltrán
Etymology: Juno was a Roman goddess, the equivalent of the Greek Hera, queen of the gods. Juno was a majestical figure, wearing a diadem on her head. The peacock is her symbolic animal. Juno is also the guardian of the Empire's finances and considered the Matron Goddess of all Rome. The month of June was named after her (JUNO).
Early stages: Eggs are red and approximately 1 x 0.7 mm (h x w). Females usually place 60 to 100 eggs under leaves of the host plant. Mature larvae have a brown body with orange spots, with black scoli and head; length is around 0.1 cm. Caterpillars are gregarious (Brown, 1981).

Dione juno occurs from sea level to 1200 m in open forests. Usually individuals fly rapidly in the middlestory. Adults roost in loose groups at night lower than 2 m above ground on grass blades and leaves (Brown, 1981, DeVries, 1997).
Hostplant: D. juno larvae feed primarily on plants from the genus Distephana, Tacsonia, Grandilla and Plectostema (Brown, 1981). In Costa Rica D. juno feed on Passiflora vitifolia, P. alata, P. platyloba, and P. edulis (DeVries, 1997).
