Orchard Butterfly
Papilio aegeusAlso known as Orchard Swallowtail Butterfly, Large Citrus Butterfly
Orchard butterflies are among the largest butterflies in eastern Australia, featuring dramatic sexual dimorphism where females display prominent red and white crescent markings. Early stage caterpillars resemble bird droppings to deter predators before transforming into plump green larvae equipped with a foul smelling red organ called an osmeterium. Adults flutter lazily through suburban gardens, citrus orchards, and coastal rainforest margins in search of nectar rich flowers.

Responsible observation
- Plant Host Trees: Grow native citrus or domestic fruit trees to attract egg-laying females to your garden.
