Roridula

Description
Roridula is a genus of carnivorous plants that belong to the Roridulaceae family. It is native to South Africa and consists of two species: Roridula dentata and Roridula gorgonias. Unlike most carnivorous plants, Roridula does not produce enzymes to digest its prey. Instead, it relies on a symbiotic relationship with a species of bug called Pameridea roridulae. The Roridula plant secretes a sugary liquid that attracts the bug, which feeds on the liquid and the trapped insects on the plant’s sticky hairs. In return, Pameridea roridulae provides the plant with nutrients from its excrement.
