Beetles with benefits

Cat's Claw Creeper is a woody vine native to tropical America that has become an invasive species in Australia since its introduction. This aggressive vine climbs trees, suffocating the host tree. As a perennial, it outcompetes native vegetation by forming dense mats that choke out ground covers and seedlings. EcoInsects is addressing this issue by introducing two highly effective biocontrol agents, the Tingid and Jewel beetles. These beetles have proven successful in limiting the spread of Cat's Claw Creeper.

What does Cat's claw creeper look like?

Its distinctive green leaves grow opposite one another, each featuring two leaflets. True to its name, the vine produces unique, claw-like tendrils with three prongs. The young leaves often emerge in a striking reddish-brown color, gradually transitioning to green as they mature.

In spring and summer, the plant blooms with vibrant yellow, trumpet-shaped flowers, each with five petals.

The seed pods, initially green, mature to a rich brown color and can grow up to 45 cm long. Inside, each pod contains 40 to 80 seeds, which are carried away by the wind and water for dispersal.

Young vines are smooth and green, but as they age, they develop a light brown or gray, woody texture. Older stems produce short, hair-like rootlets that help the vine cling to surfaces as it climbs.

The plant also has extensive tubers that grow deep into the soil, enabling it to spread efficiently.

How is it controlled?

Much like the vine itself, Cat's claw creeper requires a comprehensive, three-pronged approach for effective management: prevention, early intervention, and long-term control. This approach combines physical, chemical, and biological methods.

The most effective control strategy depends on available resources and the scale of the infestation

What are my biocontrol options?

Biological control leverages natural predators to manage the spread of Cat’s claw creeper. When releasing insects for control, it's crucial that the vine is healthy and not affected by drought. Marking the release site ensures you can monitor the insects' progress each season.

In Australia, three biocontrol agents have been introduced to target Cat’s claw creeper. These insects are host-specific, meaning they can only feed, breed, and survive on the vine.

Hedwigiella jureceki – Jewel Beetle
Preferring sunny areas, the Jewel Beetle targets Cat's claw creeper as it climbs into the tree canopy.
Carvalhotingis visenda – Tingid Bug
The Tingid Bug thrives in shady areas where Cat's claw creeper spreads along the ground.
Hypocosmia pryochroma – Leaf-Tying Moth
This moth favors riparian environments where the vine climbs into the tree canopy.
