In North Carolina, the United States, a hungry fly rammed through the pine forest. It was attracted by the nectar-like aroma of bright red flower-shaped objects on the ground and landed on its rosy plump leaves. The fly took a sip of the sweet sap from the leaves, rubbed its leg against one of the small fluffs on the leaf, and then rubbed another fluff. Suddenly, the world of flies was wrapped in a wall, and the two sides of the leaf were closed in the middle, and the spines on the edge snapped together like the sharp teeth of a trap. When the fly was struggling to escape, the beast clip had closed the door tightly. At this time, the leaf surface stopped supplying nectar and began to release digestive enzymes, which eroded the flies' internal organs and gradually turned them into viscous objects. This fly has experienced the worst thing that hurts its self-esteem as an animal: it was killed by a plant.
This is a section about the mechanism analysis of the Venus flytrap. I think this description is very interesting, and it also points out several characteristics of the Venus flytrap very vividly.
First, the Venus flytrap has a strong attracting power, it looks good, it has a fragrance, and it has sweet juice; second, the Venus flytrap is very smart, and it can catch the best time to catch prey. And, at the moment of catching, it is so smart that it continues to confuse its prey with nectar and relax its vigilance; third, the powerful destructive power of the Venus flytrap—a small plant can actually digest a small animal. This is Up the killing across a class.
So the fly paper got inspiration from this little plant. It uses attractants to fool the insects, and then uses the mucus to trap the insects until it dies.
But the difference is that it takes time for the Venus flytrap to digest its prey before it reopens its "trap". For the Venus flytrap, getting nutrients from the prey is the most important thing. responsibility. But the fly paper does not need to be digested. Its function is just to kill. No matter how much the paper has been killed, as long as the lure is strong enough, the flies will continue to flow in an endless stream, coming one after another to find death.
I once saw a video that people simulated-the world through the eyes of a fly. Although flies do not have a single eye with one pupil like humans, flies also have eyes. Its eyes are composed of thousands of small compound eyes. The video uses the word "mosaic" as a metaphor. That is to say, the fly does not see things as clearly as people see, but its eyesight is enough for it to grasp all aspects of the situation, and the weak photosensitive system is enough to ensure that it can judge. The source of the object.
Therefore, for the flies, the reason for being hunted by the fly paper may not be because they did not know that this was a trap. It is very likely that they have grasped the situation that this is a trap. However, they still choose to go to it. , They might think that they will become the lucky ones who can retreat after a feast, right?
But the fact is, fly paper won't let its prey feast at all, it will only make it sure to die.
Finally, let's go back to the movie "Flycatcher", I think it is just like the name.
The film "Flycatcher" (2011 U.S.)
