What’s Happening - 2025

Brisbane is home to one of Australia’s most stunning yet endangered butterflies—the Richmond Birdwing (Ornithoptera richmondia). Once common in the region, this vibrant species has faced significant population declines due to habitat loss and invasive plants. Now, Bald Hills Bushies are helping other local conservation groups who are stepping up efforts to ensure its survival. The Richmond Birdwing is one of Australia’s largest butterflies, with males boasting striking green and black wings, while females are larger with brown and white markings. Historically, these butterflies thrived in Brisbane’s subtropical forests, but as urban development expanded, their essential breeding plant, the Richmond Birdwing Vine (Pararistolochia praevenosa), became increasingly rare Adding to the challenge is the Dutchman’s Pipe Vine (Aristolochia elegans), an introduced species that resembles the native vine but is toxic to the butterfly’s caterpillars. The female birdwings mistakenly lay their eggs on it, dooming the next generation before it even begins. To help other conservation groups who are trying to combat the species decline, Bald Hills Bushies have planted 15 Richmond Birdwing Vines in our Bushies Shed Bed. We also encourage residents to cultivate the vine in their own backyards to create safe breeding sites. Bald Hills Bushies have also been active in removing Dutchmans Pipe from our beds. With continued conservation efforts, Brisbane’s iconic Richmond Birdwing butterfly may once again become a common sight in local gardens and reserves. Each vine planted and each butterfly spotted brings hope for the species’ future
