Wildflowers in the Woods: pitcher plants. The leaves of this plant give it its name: four to ten inches long, they are shaped like pitchers, heavily veined with purple streaks, half-filled with water, and lined with bristles that trap insects. A sweet substance secreted by nectar glands along the leaf edges attracts insects, while downward-pointing hairs encourage them to descend further and prevent them from climbing back out. Sticky cells on the inside of the leaves adhere to their feet, making it even harder to move. Eventually, they slide down, exhausted, into a pool of liquid at the bottom, where digestive enzymes and bacteria break them down.
Surprisingly, some insects make their homes in or on the pitcher plant, including mosquitoes that spend the winter there and a fly species whose larvae feed on the remains of other insects that fall into the plant. Spiders spin webs across its mouth, and tree frogs sit on the lip, waiting for unsuspecting prey.
