New Zealand flatworms are predators that primarily feed on earthworms, which can have devastating effects on soil health and garden ecosystems. Their flat, ribbon-like bodies are uniquely adapted to slip through the soil, and their dark purple coloration helps them blend into the shadows beneath pots and stones, where they often hide during the day.
3. How To Positively Identify A New Zealand Flatworm
Identifying a New Zealand flatworm can be done by noting several distinctive characteristics. First, look at its color: a dark purple or brown body with a pale border is a clear indicator. The flatworm’s body is flat and elongated, measuring between 5 to 15 centimeters in length, although larger specimens have been reported.
These flatworms are smooth to the touch and lack any visible segmentation, unlike earthworms. When disturbed, they may curl up or attempt to escape by gliding along the ground. Observing these behaviors, along with their physical traits, can help confirm their identity.
