Venus' flytrap growing wild in the swamp

Best viewed large On Black. The Venus's-flytrap (Dionaea muscipula) uses its claw-like leaves to capture insects. Trigger hairs sense when an insect has landed. If two or more trigger hairs are touched, the trap springs shut. Digestive enzymes consume the soft parts of the insect within a few days and then the trap reopens, redy to catch its next meal.
Aren't they cute? Such a fun project! These seedlings got just big enough to pot them up at the very end of the semester.
Charles has only been here a couple of months, but survived almost completely drying out while adjusting from the grocery store, and sprang back from it healthy and strong. He has 2.5 inch long leaves and 1 inch traps, shows potential for good color next year.
To trigger closing of a venus flytrap leaf, the intruder must touch one of four hairs twice, or touch two different hairs in rapid succession.

The Venus Flytrap, Dionaea muscipula, is a carnivorous plant that catches and digests animal prey—mostly insects and arachnids. Its trapping structure is formed by the terminal portion of each of the plant's leaves and is triggered by tiny hairs on their inner surfaces. When an insect or spider crawling along the leaves contacts a hair, the trap closes if a different hair is contacted within twenty seconds of the first strike. The requirement of redundant triggering in this mechanism serves as a safeguard against a waste of energy in trapping objects with no nutritional value.
