The peculiar shape makes it the favorite of the flower market. But in fact, this pigsty is just a abnormal leaf, and there is nothing special about it. A tendril grows on the leaf and clings to other plants. The tip of the tendril gradually forms a cup to produce a "lid", which is the so-called bottle shape.
Pitcher is not born to be able to insect, but in the bad environment, its own growth can not get enough nutrients, and use its own sometimes, prey on insects.
In Huashi, the florist will kill mosquitoes with pitcher plant grass in Xuancheng. Actually, mosquitoes are not the meal of pitcher plant grass. It's hard to believe that pitcher plants mainly eat ants and other land insects.
In fact, the mosquitoes sucking human blood at home are all female mosquitoes. They can feel the human breath and the infrared ray emitted by people, and find the target. But pitcher plant grass mainly emits ultraviolet rays, which can't attract female mosquitoes at all. It can only attract male mosquitoes that suck plant juice. It's really useless for indoor mosquitoes.
pitcher plant is not only ineffective in killing mosquitoes, but also easy to help mosquitoes. When pitcher plants eat mosquitoes, they will be in the bottle, but sometimes they will lay eggs and feather in the bottle. Instead, the pitcher plant bottle becomes a place for mosquitoes to live. Larva caught by pitcher plant will become mosquito food. Gradually, there will be a mutually beneficial relationship between pitcher plants and mosquitoes. The emergence of mosquitoes can attract mantis, spiders to come to prey, just become the food of pitcher plant grass, and pitcher plant grass can provide mosquitoes with an undisturbed spawning environment. The two sides reached a balance, which seems to be totally inconsistent with our original intention of buying pitcher plant grass to kill mosquitoes.
