are the ones that are insectivorous,
like the one above, a Venus fly trap, (Dionaea muscipula), I like many others thought that for the trap to shut, the insect would have to hit 2 'hairs' within the trap for it to close, and apparently for 200 years, scientists have been studying how the trapping
mechanism of Venus flytraps work. It is now known today that touching trigger
hairs twice within 30 seconds would make the trap snap in an instant. New
research from the University of Zurich (UZH) and ETH Zurich, however, found
another way that could make the trap snap immediately: by touching it slowly, "Contrary to popular belief, slowly touching a trigger
hair only once can also cause two signals and thus lead to the snapping of the
trap," says co-last author Ueli Grossniklaus, director of the Department
of Plant and Microbial Biology at UZH, scientists theorize that this happens to catch slow-moving
larvae and snails, more details about this over at ScienceDaily, I took the above photograph when we were living in Thailand and went to our local weekend plant market, and you know what I am going to say next, if only we had a garden!
