Sticky glands from a Cape sundew
Drosera capensis, or the Cape sundew, is a carnivorous plant covered with sticky tentacles. Insects become trapped in the sap-covered tentacles and activate the plant’s touch response, called thigmotropism. Within thirty minutes, the sundew rolls its leaves towards its center, ensnaring and enveloping its prey in digestive juices.
