Venus Flytraps Are Even Creepier Than We Thought
If you accidentally get transformed into a fly, and get caught in a Venus flytrap, here is some valuable advice: Don’t panic.
“If you just sit there and wait, the next morning, the trap will open and you can leave,” says Ranier Hedrich from the University of Würzburg. “It you panic, you induce a deadly cycle of disintegration.”
Hedrich and others have found that the Venus flytrap can count the number of times that its victims touch the sensory hairs on its leaves. One touch does nothing. Two closes the trap. Three primes the trap for digestion. And five, according to Hedrich’s latest study, triggers the production of digestive enzymes—and more touches mean more enzymes. The plant apportions its digestive efforts according to the struggles of its prey. And the fly, by fighting for its life, tells the plant to start killing it, and how vigorously to do so.
