When the insect is caught by the two leaflets and helpless to get rid of, the insect in the process of struggle the leaf will be clamped tighter and tighter until almost closed, at this time the inner glands of the two leaf lobes collected by the luminal glands will excrete the digestive juice, the application of these digestive juices contained in the protease, the insect protein differentiation into nitrogen, oxygen, carbon, hydrogen mainly, may also contain the rest of the elements of the amino acids and stop receiving.
It usually takes about four days for you to differentiate and receive the more digestible parts, and then continue to receive the remaining nitrogen, phosphorus and other required trace elements. After these nutrients are received, the leaf petals will be closed again, and the whole time will take about 5 to 10 days, at which time only the empty shell remains composed of chitin remains.
In addition to flytraps, they are helpless to distinguish the size of the catch, and occasionally they may catch something similar to the size of the leaf, such as a small field chicken or a long-legged wasp. At this time, it will always form too late to differentiate the reception, and the flycatcher itself will rot first, so that the leaves will appear as ordinary and withered as food poisoning. In addition, each leaf can be caught about 3 to 4 times, and the leaves will hang and wither across this number of times.
