A friend said: In the mountains, we often see "white foam" on the leaves of some plants, and the rural elderly say that it is the saliva of the snake, is this true? Seeing this problem, the first reaction of science and agriculture is snake berry, when I was a child, I often can see snakeberries in the field, snakeberries are often foamed on top, red fruits look very cute, but adults in the family have been warning children that this fruit can not be eaten, the foam on the top is the saliva spit of the snake, is this really the case?

<h1>Is the white foam on the plant the saliva of a snake? </h1>
These bubbles are not the foam spit out by the snake, but most of them are also left by the animals, and which animals are left behind, here science Xingnong will share with you. The first animal that may leave a bubble on a plant is a frog. Many friends should wonder if frogs should lay eggs in the water? And the color of frog eggs is generally transparent, why is it like foam? In fact, this is not an ordinary frog egg, but an egg laid by a tree frog.
Tree frogs are much smaller than ordinary frogs, and many tree frogs look very cute. Tree frogs will choose plants close to the water source as spawning sites during the spawning season, and the eggs of tree frogs look like clusters of white foam from a distance, and if you look closely, you will find that these bubbles are actually the eggs of tree frogs. Tree frog eggs usually hatch within a week or so, and the hatched tadpoles will grow with the rainwater.
In addition to frogs, these bubbles may also be foam cicadas, and from the name we can feel that this should be a small insect related to foam. The cicada is a very small insect, generally less than a centimeter long. There are also some other names such as thrush and blowing insect. The cicada often hides its body in a pile of bubbles, which are made by the cicada's own body, and the foam can hide itself very well, avoid the attack of predators, and keep the body moist. If you see a pile of foam on top of a tree branch, take a closer look at whether there are small bugs hidden inside.
