Killer plants - this is how you can call such types of insectivorous plants as Venus flytrap, sundew and fattyanka
As usual, one of the most "dangerous" plants for insects was named after the goddess of love. The plant is small, with leaves from 3 to 7 cm. Long trap leaves are formed after the plant has bloomed.
The Venus flytrap, like many other insectivorous plants, grows on soils that are poor in nitrogen (for example, in swamps); it compensates for the lack of the latter by mercilessly eating insects, and even small mollusks (slugs). The Venus flytrap grows in the temperate climate of the Atlantic coast of the United States.
The plant instantly slams the two-leaf "thorny" trap when touched twice. If the victim could not get out of this crypt, the edges of the ends close up more and more tightly until the trap closes completely, then the process of digesting the prey begins. It lasts about 10 days, after which the trap is opened again hospitably. For the entire period of life of one trap, an average of three insects become its victims.
Toilet bowl for tupayev
In general, this plant is called nepentes or pitcher. It grows mainly in tropical Asia, but it is also found in Madagascar, New Guinea, and Northern Australia. Named after nepenthom - the herb of oblivion, a cure for sadness, mentioned in ancient Greek mythology.
This insidious plant lures insects with its sweet scent. When the victim sits on the slippery rim of the nepentes jug, it immediately slides into his insatiable and deep womb.
Who would have thought that attractive jugs of large nepentes, which look like champagne glasses, small tropical animals - tupai - can be used as … a toilet bowl. Tupai, of course, are not familiar with the rules of hygiene, so they climb onto the nepentes water lily solely to feast on the sweet nectar, but the "convenient" design of the jug probably facilitates emptying. Meanwhile, that is what the plant needs - in addition to insects, it is not averse to "feasting" on the feces of tupai, which are an excellent fertilizer for it.
But this plant has probably been seen by many with their own eyes. But, perhaps, they did not even suspect that in front of them was a real "serial killer" of insects. Sundew leaves secrete a sticky substance - the alkaloid konyin, with the help of which the plant paralyzes insects that have the misfortune to sit on it. After this did happen, the edges of the sundew leaf close, trying to cover the whole insect, and digesting it alive. Interestingly, sundew leaves react only to protein foods, and "refuse" all other "inedible chemistry" - for example, a drop of water or a leaf that has fallen on a sundew.
Not all carnivorous plants use "active" traps, many use "passive" ones. The latter include, for example, the common zhiryanka, which can also be easily found in the vastness of our vast homeland. The mechanism of "killing" in fat women is simpler than in sundews and other "active" predators. She uses only sticky leaves, which are covered with glands that produce both sugar (which attract insects) and digestive enzymes (digesting insects). However, if the insect is large, the fatty, like its active relatives, is able to slightly roll the leaf in order to fix its prey more firmly.
