The strangest thing is its insect catching organ-insect catching cage. When pitcher plants grow new leaves, there will be rudiments of insect traps at the bottom of cage vines. At first it was yellow-brown, gradually turned red, and began to expand, forming a cage cover. The mouth of the cage has lips, which gradually develop, widen and enlarge, and turn outwards. At this time, the insect trap is mature and can catch insects!

2. Cage body

The cage can be green, orange, red and other colors with white spots. When a bug falls into a bottle, the bottle will darken from the outside, but the white spot will obviously brighten.

3. Cage cover

The cage is covered above the cage mouth, which can obviously prevent rainwater from entering and avoid polluting the acidic liquid in the cage. It can also block the light and prevent insects from escaping from the cage.

4. Cage mouth

The openings of insect traps are divided into two types: parallel cage openings and inclined cage openings.

5. Lips

The rolled-up part outside the insect trap is the most vivid. Lips can secrete juice, which is quite smooth, but the insects slide directly into the bottle when they touch it.

Extended data:

Nepenthes have strict entry requirements.

Nepenthes is a tropical insect-eating plant with gorgeous appearance and the edge of the bag mouth rolled inward. The cover surface of the bag-shaped body can secrete fragrance to attract insects. When the attracted insects stay at the edge of the bag mouth, the bag mouth will slide into the bag because it is rolled up and smooth. According to Xinhua News Agency. Com, Nepenthes has a tubular or pot-shaped "bag" in which digestive juice is stored, and Nepenthes will use drowned insects falling into the digestive juice as its own source of nutrition.

Many domestic businesses are "discerning" and want to sell pitcher plants to solve the problem of mosquito bites. I'm afraid this kind of behavior is not feasible in China. Nepenthes is a kind of reproductive seedling with certain biological aggression, which is listed in the List of Animals and Plants, Their Products and Other Quarantine Objects Prohibited from Entering People's Republic of China (PRC).

In China, there are strict quarantine regulations for carrying and mailing propagation materials such as seedlings into the country. You need to apply for quarantine examination and approval in advance and obtain a quarantine permit before you can enter the country at the designated port.
