Pitcher plants are types of carnivorous plants that have leaves shaped as a pitfall trap with digestive fluid inside. Such plants derive most of their nutrients from consuming insects that fall into the trap, mainly owing to a slippery inner surface of the pitcher. It has been argued that the digestive fluid, which in some species is highly viscoelastic, plays an important role in retaining the pray. In this talk I will discuss a mathematical model of an insect leg moving in the fluid, which aims to estimate the amount of force required for the insect to escape.
