Roridula (pronounced /rɒˈrɪdjʊlə/; from Latin roridus "dewy") is a South African genus of plants that, whilst having many of the adaptations of a carnivorous plant, such as the possession of insect-trapping sticky hairs, does not directly digest the animals it traps. Instead, it has a mutualistic relationship with Pameridea roridulae, a species of capsid bug, which lives on the plant and feeds on the trapped insects. The plant obtains nutrients from the droppings of this symbiotic insect. Whether this plant is regarded as carnivorous or protocarnivorous is essentially a matter of semantics. The genus contains just two species, Roridula gorgonias Planch. and Roridula dentata L., and is the only genus in the family Roridulaceae.
