Slime used to trap insects

Carnivorous plants are some of my favorite plants. I’ve a Nepenthes who has pitchers big enough to catch small rodents, lizards and some of the Texas sized bugs we have down here. It was thought the trap was enough now we know they slime their prey as well.

. . Since Charles Darwin’s time, the mechanism of insect-trapping by Nepenthes pitcher plants from the Asian tropics has intrigued scientists but is still incompletely understood. The slippery inner surfaces of their pitchers have – until now – been considered the key trapping devices, while it was assumed that the fluid secretions were only concerned with digestion. Gaume and Forterre were able to combine their separate expertise in biology and physics to show that the digestive fluid of Nepenthes rafflesiana actually plays a crucial role in prey capture.
