The structure of the insect trap bottle is quite special. There is a lot of wax on the inner wall of the bottle, which is very smooth. There are about 6.5438+0 million digestive glands in the inner wall from the middle to the bottom. Nepenthes can secrete a large amount of colorless, transparent and slightly aromatic acid ft-killing liquid after catching insects. This digestive juice contains amines and toxins that can paralyze and poison insects. Usually, there is always about half a bottle of this digestive juice in the insect trap. At the same time, there are many nectaries on the inner side and edge of the bottle cap, which can secrete fragrant and sweet honey juice to attract insects. Opening the lid of the honey pot will attract many greedy insects. Once the bug falls into the honey pot, the lid will automatically close immediately, and the bug will be poisoned and die soon. Soon, all the limbs were digested and the nutrition of the grass was absorbed. Then the lid of the "honey pot" will be opened again, waiting to catch the next prey.
