Description

The butterflies seldom come close to the ground and females are usually seen flying near mistletoe clumps high in eucalyptus trees and, in the case of males, patrolling and combatting rival males on hill tops. Eggs are laid on or under bark of the ecalypt, usually within a few metres of the ground or hollow limbs that support temporary nests of the sugar ants. Few to many (50 or more) eggs may be laid at the one site. Many young larvae may shelter under bark near the mistletoe but larger larvae shelter with the ants near the base of the tree, often underground in chambers excavated by ants or under litter or rocks at the base of the tree. At night the larvae emerge with ants to scale the tree and feed on the mistletoe leaves. Pupation generally occurs in the ant nest or under loose bark on the trunk of the tree, the pupa attached to a silken pad by anal hooks and a silk girdle. In souther and central Vic there is one generation a year but in the northern malle there are two generations.
