[1] After devouring the captured arthropods, bugs in the genus excrete waste, which the plant absorbs using glands, making it an example of symbiosis.

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.

Without the Roridula, Pameridea cannot find a food source and ultimately die.

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.
