Oenosandra boisduvali - the male of this species, shown here, has an interesting speckled pattern on the forewings. It is a sexually dimorphic species - the female has white forewings with a narrow longitudinal stripe of the same pattern as the male’s wings. As befits its name, the adults make their first appearance in early autumn and are gone by the start of winter. The larva feeds at night on Eucalyptus leaves, hiding beneath the bark of the tree during the day.
