The growth process of the cicada, the development process of the cicada is several stages

Cicadas generally start from the silkworm pupae, in June-July, the pupae become adults, and begin to lay eggs within a few days, from eggs to larvae, cicadas live underground, when a black crack appears on the back of the cicada pupa, the process of molting begins, and the cicada has to go through many times of shedding before it can become an adult.

Cicadas live in temperate to tropical regions of the world (about 2,000 species of cicadas have been recorded). Some species found in desert areas will expel excess water from the tergum when the body temperature is too hot, which will cool and dissipate heat.

The growth process of the cicada is that it will change from a pupae to an adult in June and July every year, and then lay eggs in just a few days, starting from the eggs, until the nymphs live in the ground, until the last time they shed their shells and become adults, chirping in the trees, this period is usually one to two years.

nbsp;In the summer evenings, we can always hear the chirping of cicadas on the trees, and the cicada was originally a pupa, which everyone knows, so what is the growth process of the cicada? Let me give you a science about the growth process of cicadas.

Details:

Ovum. Cicadas will turn from pupae to adults in June and July every year and then lay eggs in just a few days, the eggs are in late May to early June of the following year for the peak incubation period, and the hatching activities end in late June, mostly in the afternoon during the day.

Larvae. The larvae of the cicada live in the soil, have a pair of strong digging forefeet, suck the sap at the roots of the host plant, are less mobile, usually stay in the soil for a few years, and then burrow into the deep soil layer after the temperature drops in the autumn, and then migrate upward to the roots of the tree after the spring is warm.

Eclosion. After the cicada completes the whole life process of the nymph in the soil, the mature nymph emerges from the soil from late May to mid-to-late August, crawls to the branches of shrubs, weeds, stems, etc., and fixes itself on the bark branches and leaves with its claws and forefeet, and molts and feathers.

Imago. After feathering, after a period of stretching, it becomes an adult. Usually mid-June to mid-July is the peak period for adult worms, about 20 days after the adult emerges, the tail lays eggs, after laying eggs, the adults will die, and the eggs begin to hatch into the next life cycle.

There are four stages in the development process of cicadas, which are cicada eggs, larvae, pupa, and adults.

1. Cicada eggs: cicadas will change from pupae to adults in June and July every year, and then lay eggs in just a few days, eggs in late May to early June of the second year for the peak period of incubation, late June hatching activities are over, mostly hatching in the afternoon during the day, accounting for about 80%, less hatching at night, about 20%, and the egg period is close to 300 days.

2. Larvae: The larvae of the cicada live in the soil, have a pair of strong digging forefeet, suck the juice at the roots of the host plant, have less activity, usually stay in the soil for several years or more than ten years, the temperature drops after autumn, they burrow into the deep soil layer for winter, and then migrate upwards to the root of the tree after the spring is warm, and the number of nymphs in the soil is the largest in May of the year.

3. Pupa: The mature larvae of cicadas emerge from the soil from late May to mid-to-late August, molt and feather into adults.

4. Adult: mid-June to mid-July is the peak period of adult appearance, early October is the end stage, the adult emerges about 20 days after the tail spawning, the late June begins to lay eggs, the end of June to the end of August is the peak period of adult oviposition, the end of September to early October is the end of oviposition, and the final period is early November.
