Description

Perennial species, height about 500 mm, they are covered with sticky glands which capture insects, much like Drosera does. It has been discovered that the plants do not assimilate the nutrients from the dead insects (the sticky material is a resin and not a mucous), so Roridula is not a carnivorous genus in the narrowest definition. The Roridula plants have a relationship with bugs in the genus Pameridea. Roridula captures plenty of prey with its sticky resin, but these are soon eaten by the Pameridea bugs that wait around on the leaves. Then, the excrements of the Pameridea bugs, which contains useable quantities of the nutrients needed by the plant, are absorbed by the leaves of Roridula.
