The time when cicadas come out of their holes in the Book of Insects
About the original text of this part:
On the solstice of summer, the earliest cicadas appeared. Where the sun shines, people come and go, the path is trodden firmly, and there are some finger-thick round holes on the ground, through which cicada nymphs climb from the ground to the ground and emerge into cicadas. There are round holes everywhere except the ground where crops grow. They are usually located in the hottest and driest places, especially on the roadside. With sharp tools, it can penetrate sand and dry soil, and it likes to drill out of the ground from the hardest place.
This article in Entomology, written by French entomologist Fabres, introduces the physiological habits, vocal principles, growth process and natural enemies of cicadas. ?
The personality characteristics of cicadas in insect stories are:
1, cicada larvae live in the soil, suck the juice from the roots of plants, weaken the tree and make the branches shoot? Dead, affecting the growth of trees.
2. Cicada larvae live in the soil all their lives. When it is about to emerge, drill out of the ground at dusk and night, climb to the tree, and then grab the bark to shed its skin and emerge.
3. In summer, trees cry loudly, so it is harmful for trees to suck tree juice with needle-like mouthparts. Larvae inhabit the soil and suck juice from the roots.
4. There are different kinds of cicadas with similar shapes and different colors. Cicada has three less sensitive eye spots between its eyes and a simple supporting tubule on its wings.
5. The tenor singer in the cicada family is a kind of cicada called "double drummer". There are large ring-shaped vocal organs on both sides of its body, and a disk that can be opened and closed inside and outside is in the middle of its body. The opening and closing speed of the disc is very fast, which is the reason for shaking cicada.
