The General Assembly of 2005 adopted the Venus Flytrap (Dionaea muscipula) as the official State Carnivorous Plant (Session Laws, 2005, c. 74).
The trap is activated when an insect (or other object) brushes 2 or more times against bristles that grow on the surface of the leaf. The trap springs shut in less than a second, but doesn't close completely until it has determined (either chemically or through movement) if it has caught worthwhile food. If it has, the trap gradually seals completely shut, allowing digestion to take place. It reopens in 3 days to 2 weeks.
