The relationship with Roridula consists primarily of the fact that Roridula produces a resin that cannot digest captured insects like other carnivorous plants such as Dionaea muscipula, Drosera, Pinguicula, and Nepenthes.
Thus, P. roridulae and P. marlothii devour the trapped insects on the Roridula and then excrete waste that is consumable by the plant to supplement its diet, since it grows in nutrient poor soil.
Without the Roridula,  Pameridea cannot find a food source and ultimately die.

Because P. roridulae and P. marlothii eat and digest the food for the plant, some carnivorous plant enthusiasts consider Roridula only sub-carnivorous.
However, Sarracenia purpurea uses a variety of worms to digest captured arthropods for them, as does Darlingtonia californica, and these plants are generally considered carnivorous.
Pameridea have special feet with hairs on them that allow them to run through the plants' resin without being caught in it.
