With goblet-shaped leaves, pitcher plants collect rainwater to … This is the first recorded case of a Northern Pitcher Plant regularly capturing vertebrate prey.

A juvenile spotted salamander is seen inside a pitcher plant in this undated photo (Patrick D. Moldowan) Canadian researchers have discovered that carnivorous pitcher … Sarracenia purpurea, the purple pitcher plant, grows naturally in the Suffolk County Boglands.Some of their habitats are along the tributaries to the Peconic River, others in sunny and wet meadows of Sphagnum moss among the watershed. It is possible that vertebrate prey may be more common among carnivorous plants than we ever thought! This location is on a floating Sphagnum mat in the middle of a pond, surrounded by uplands woods, and this place is of special interest because of its history. Another possibility, researchers say, is that the salamanders are attracted to the small insect prey in the plants. According to the researchers’ observations, the plants are a “non-trivial source of mortality” for baby salamanders. To make matters worse for the salamanders, Moldowan suspects some “clever birds” visit the plants looking for an easy meal.
