Trap Architectures

Diversity of Carnivorous Capture Strategies

Pitfall Traps

Example: Nepenthes, Sarracenia

A passive trap where leaves form a deep pitcher. Prey slips on the slippery peristome and falls into a pool of digestive enzymes.

Snap Traps

Example: Dionaea muscipula

An active trap triggered by touch. Rapid cell volume changes cause the lobes to snap shut in less than a second.

Flypaper Traps

Example: Drosera, Pinguicula

Sticky mucilage droplets mimic nectar. Once the insect is stuck, enzymes begin the external digestion process.

Suction Traps

Example: Utricularia

A high-speed vacuum trap. When a trigger hair is touched, the bladder door opens and sucks in prey within milliseconds.
