Perhaps more accurately, the others haven't been examined for carnivory.
Just having inverts stick onto and die on a plant does not really
satisfy the requirements to be considered carnivorous. But apparently
some studies have been made in which nutrient absorption was demonstrated
with _I.lutea_.

Sounds like my _Stapelia gigantea_ as well. Nasty plant. When it flowers,
run away!
