How Do Carnivorous Plants Trap Insects?
One of the common trapping mechanism used by numerous carnivorous plants is the flypaper trapping mechanism. Here in the plant secretes a glue like substance through their mucilage glands. So, as soon as an insect sits on the plant, it is besieged. Plants like sun dew plants and butternuts make use of this trapping mechanism to catch insects. Insects like flies, mosquitoes and fungus gnats can be easily caught using this mechanism.
Some carnivorous plants use a pitcher type of trap to catch insects as well as big organisms. There are some plants that have plant pitchers. These pitchers are large enough to hold even big organisms like rats and other rodents. Such plants have a long chamber that leads to the pitcher. So, when an organism settles down on the plant, he slips through the chamber to reach the pitcher. Since the pitcher of these plants is full of acid, digesting even big organisms isn't tricky.
Another trap mechanism which is well followed by many carnivorous plants is snap trap mechanism. This mechanism involves the plants to open their leaves and wait for the prey to sit on them. Whenever the prey settles on such leaves, the leaves straight away close down. As the leaves close down the prey gets surrounded. The leaves of the carnivorous plants remain closed for a long time. The leaves in fact remains closed till the catch is totally digested. Though there are several carnivorous plants that use this technique, there are some which are famous for following this technique to the maximum possible extent. Some such carnivorous plants are waterwheel and Venus Flytrap.
Yet another trapping mechanism of the carnivorous plants that's unknown to several to many is the lobster pot trap. These carnivorous plants trap the prey by giving a straightforward entry to the prey. The prey isn't allowed an exit once it enters. As the prey or the catch enters the plant, it loses its way to come out and so remains encircled. It has been observed that such trapping mechanism is in general followed by the nautical plants. Some plants that follow this kind of trapping system are genlisa plants, corkscrew plants and many more.
There are some meat eating plants that fall in the category of borderline carnivores. These plants do not eat the prey. Instead, they soak up the nutrients of the encircled insect and then leave them. Plants like catopsis barteroniana, and Ibicella lutea make use of such a prey catching mechanism.
These wonders of nature are more than fascinating with their carnivorous traits. In the final analysis, it just proves how versatile and unique Mother Nature's creations truly are.
