Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Containing group: Dione

Introduction

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).

Characteristics

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).

Habits

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).

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
