Mallee Bronze Azure Butterfly
The Mallee Bronze Azure butterfly embodies everything that makes Australia’s insects extraordinary — striking in appearance, uniquely Australian and ecologically remarkable.
The Mallee Bronze Azure butterfly's brilliant, iridescent wings are matched by an incredible life cycle.
The species has an obligate relationship with native Brown-bearded Sugar Ants. Butterflies lay their eggs next to ant nests where upon hatching the caterpillars descend underground to grow.
By celebrating this insect, we celebrate the importance of protecting entire ecosystems and the overlooked invertebrates that keep them functioning. It’s a powerful ambassador for biodiversity, proving that even the smallest species can inspire conservation and make a lasting impact.
The Mallee Bronze Azure Butterfly is a finalist in the 2026 ABC Insect of the Year!
Voting is now open and this year features a species Zoos Victoria is fighting to save from extinction as nominated by Invertebrate Conservation Coordinator, Jessie Sinclair.
Voting closes 30 October 2026.
Major threats

Our plan for recovery
Through research, habitat protection and conservation action, Zoos Victoria and Mallee Conservation are working to support existing populations and identify opportunities to establish new ones.
