The Plumbago Blue has become a rather common and widespread species along eastern NSW and QLD, because Plumbago shrubs, the larval food plant, are popular ornamental plants in suburban parks and gardens. The butterflies are often encountered fluttering around the food plants in great numbers. Females attach their eggs directly to the flower buds of Plumbago shrubs where the hatched caterpillars feed on both the flower buds and flowers. While in the northern areas the Plumbago Blue can be encountered all around the year, the species is very seasonal around Sydney where the butterflies only fly from late summer until early winter.
