Carnivory
Nepenthes talangensis produces extremely thick, mucilaginous pitcher liquid, which coats the entire inner surfaces of the traps in a thin film. The pitchers of this species appear to function at least in part as flypaper traps, with the sticky inner walls trapping flying insects above the surface of the fluid.
Similarly viscous pitcher fluid is also found in seven other closely allied Sumatran species: N. aristolochioides, N. dubia, N. flava, N. inermis, N. jacquelineae, N. jamban, and N. tenuis. Together with N. talangensis, these species all share infundibular pitchers that are wholly glandular or almost so.
