Behind the scenes of our Cat’s Claw biocontrol program 🐞🌿
Cat’s claw creeper (Dolichandra unguis-cati) is one of the most aggressive invasive vines in our region, a fast-growing climber that can smother native vegetation, block sunlight, and take over entire ecosystems if left unmanaged.
Through our program, we breed leaf-mining jewel beetles (Hylaeogena jureceki), a species that naturally targets cat’s claw vine. These beetles play an important role in a holistic control approach, helping to weaken the vine by feeding on its leaves and reducing its ability to grow and spread. They were approved for release by the Australian Government after extensive testing to ensure they wouldn’t harm native species or crops.
While they don’t completely eliminate the plant, they make a real impact. By defoliating the vine and drawing nutrients from it, the beetles slow its growth, put strain on its tubers, and help prevent further spread, giving native plants a better chance to recover.
📸 In these photos, you’ll see some of the earliest stages of that process, including the beetles’ eggs.
Jewel beetles lay their eggs directly on cat’s claw leaves, often in small, raised circular casings. Once the larvae hatch, they begin mining through the leaf tissue, feeding from within and gradually weakening the plant.
Biocontrol is just one part of the solution and can be a great starting point for infestations. Manual removal and targeted chemical control remain the most effective ways to fully eliminate cat’s claw creeper in the long term. If you’re looking for advice or support, consider reaching out to your local environmental or Landcare group, or council programs such as Land for Wildlife.
By working with nature, not against it, we’re building a more sustainable way to manage invasive species and protect our local ecosystems for the future.
