    Are these really carnivorous?

    Are these plants carnivorous? It keeps on popping up in my mind and is a pain to not know if they really are carnivorous...:
    Roridula Sp.
    Byblis Sp.
    Stylidium Debile
    Nepenthes Lowii(I know neps are carnivorous, but a video on YouTube messed my mind up with this one )
    If anyone knows if these plants are really carnivorous, can you reply? Thanks everyone!

    Roridula sort of is. There's a species of insect, Pameridea roridulae, that lives on the plant. When the Roridula traps a bug with its dew, the Pamerideas eat and digext the captured prey (they've evolved to live on the plant without trapping themselves). Their feces are what gets digested by the plant since it can't digest its prey for itself. It's a mutualistic relationship between the plant and the insect. And I'm pretty positive both the N. lowii and Byblis are indeed carnivorous.

    It's listed as quasi-carnivorous.

    To clarify, Byblis and Roridula are both thought to utilize symbiotic organisms is to help with their digestion process, as in they do not produce enzymes. Neither do Darlingtonia or Heliamphora. They require some kind of vector to aid in digestion. Just as we have bacteria in our intestines to aid in our digestion process, these plants have organisms to help them digest their food.

    But since all these species clearly demonstrate mechanisms that are meant to encourage the capture of insects (sticky leaves, nectar, ect) they can be classified as carnivorous.

    I don't consider Stylidium as carnivorous. All it does it hit the pollinator with a pouf full of pollen, it has no intention of ever consuming said be-poufed insect.

    Lil, Stylidium is considered to be carnivorous by some because of the Drosera like glands on their flowerstalks, not the pollen triggers.

    The glands are really hard to see, but apparently they do capture stuff...
