Appearance and life characteristics of cicada

Cicada is characterized by a pair of transparent wings covering the body, a wide and short head, and black eyes protruding from the body on both sides of the head. Their life characteristics are that they will survive in the soil for several years to decades. Every June, larvae become adults, and adults are used to living in trees. The life span of an adult is about one hour. By the middle and late July, adults began to lay eggs.

A North American cicada, which needs to drill for 17 years before coming out of the hole, belongs to Hemiptera. They lie dormant underground for 17 years, then attach branches to shed their skin and mate. The male cicada dies after mating and the female cicada dies after laying eggs. Scientists explained that this peculiar lifestyle of cicada for seventeen years is to avoid the invasion of natural enemies and safely continue the population, thus evolving a long and secret life cycle. There is also a 13-year-old cicada who has lived underground for 13 years, second only to the 17-year-old cicada.

Replication method

From June to July every year, pupae will become adults in just a few days, and then lay eggs. From the beginning of eggs to the process of nymphs living underground, until the last time they shell and become adults, they will make a scene in the trees. This period usually takes one to two years. In cicadas, their larvae are also called "nymphs". Their male cicada will make sounds to attract the female cicada to mate with him. It is inserting the oviposition tube at the top of it into the tree to lay eggs, and the larvae will not hatch until the next year.

After living in the soil for several years or even more than ten years, you can break through the ground. In their long life, they have to go through many shellings, and the last one is when they are adults. When it becomes an adult, it will make a sound, and the sound made by the male cicada vibrates the two eardrums in the abdomen at a high frequency of hundreds of times per second, making a sharp and loud sound to help the female cicada determine the position of the male cicada suitable for mating.
