BREAKING: The endangered Eltham copper butterfly has been spotted in multiple locations across Victoria, sparking an urgent call from conservationists for the public to report sightings. This rare butterfly, once thought to be extinct, is now facing severe threats from habitat loss and climate change, with only three known populations remaining in the state: Bendigo/Castlemaine, Wimmera, and Eltham in Melbourne.
The North Central Catchment Management Authority (CMA) has announced that there is still time to observe these striking butterflies before their flight season ends in mid-March. “Now is the best chance to get out and find them,” said Laura Chant, project manager for the North Central CMA. “They tend to be flying on hot, sunny, still days.”
This remarkable species relies exclusively on the sweet bursaria plant and the Notoncus ants for survival. The butterfly lays its eggs at the base of this plant, and the ants play a crucial role in protecting and nurturing the caterpillars. “The caterpillars mimic ant hormones and sounds to gain the ants’ trust,” Chant explained, highlighting the complex relationship between these species.
The Eltham copper butterfly was rediscovered in 1986 after being presumed extinct. Conservation efforts have led to the establishment of protected areas in Eltham, yet continued urbanization and climate pressures threaten their existence. “We can’t protect them if we don’t know where they are,” Chant emphasized, urging the community to help track their populations.
Residents are encouraged to participate by photographing any sightings and uploading them to the iNaturalist app. This collaborative approach aims to map out current populations and enhance conservation efforts.
This summer, as Victorians enjoy the warm weather, they are reminded of the critical role they play in preserving this unique species. “It’s surprising where the Eltham copper butterfly can turn up,” Chant noted, recounting a recent sighting in Flora Hill, Bendigo. “Much to my surprise, I found a thriving population just beyond a backyard fence.”
With the clock ticking on their flight season, the urgency to document and protect the Eltham copper butterfly is more pressing than ever. For more information on how to help, visit nccma.vic.gov.au/elthamcopperbutterfly.
