Cyclic cicada is a kind of cicada insect with unique life cycle, mainly distributed in North America. With a life cycle of 13 or 17 years, most of the time in the form of larvae living in the ground, sucking the juice of tree roots. Every 13 or 17 years, the larvae collectively crawl out of the ground, molt and become adults, complete mating and oviposition. Adulthood has a short life span, usually only a few weeks, and is mainly used for reproduction. The adult body is about 2.5-3cm long, with black body color, red compound eyes, transparent wings and yellow veins. Males emit calls by vibrating the tympanic membrane in their abdomen, attracting females. They have an impact on the ecosystem.

The Japanese bear cicada, also known as the black giant cicada, is a common large cicada in Japan. With a body length of about 40-48mm and a wing end length of 60-65mm, it is one of the largest cicadas in Japan. It is mainly distributed in the area west of Kanto, Japan, including Shikoku, Kyushu, Okinawa, Taiwan and the Korean Peninsula. The body color is mainly black, the surface is shiny, the body surface of fresh individuals is covered with yellow and white micro hair, and there are white stripes on both sides of the abdomen. The larvae feed on tree roots, while the adults suck sap and often gather on mulberry, poplar, persimmon and other plants. Belongs to the incomplete metamorphosis insect. It takes seven years for hatching to eclosion, while the adult life span is only about two weeks.

The mantis, also known as "cicadas", belongs to the hemiptera cicadae. It is a small cicada with a body length of about 2.5cm and a purple-blue or yellow-green color with black stripes. The hindwings are transparent except for the black margin. Males have articulators in their abdomen and can make "chi-chi" calls, which are not as loud as large cicadas, but last longer. Widely distributed, common in China, Japan, the Korean Peninsula and other places. Usually inhabited in lowland, mountainous or urban environments, with a particular preference for trees such as cherry blossoms and pines. It is one of the cicadas that appear earlier in summer. The larvae live in moist soil and feed on the sap of plant roots.

Cicadas are insects in the Cicadaceae family, commonly known as cicadas. There are currently about 2000 species of cicadas, with a body length of 2-5 centimeters. Cicadas with two pairs of membranous wings, protruding compound eyes, and the ability to sing are all male cicadas. The vocal organ at the base of the male cicada's abdomen is like a large drum covered with a layer of eardrum, which vibrates and produces sound. Due to the fact that cicadas' vocal muscles can stretch and contract about 10000 times per second, and the gap between the lid and eardrum can resonate, their vocalizations are particularly loud. However, female cicadas, due to their incomplete body structure and lack of eardrums, are unable to produce sound and are known as "mute cicadas".

Cichlids, also known as "cicadas", are insect species. Category: Cicadaceae, Cicadaceae/Hemiptera, with two pairs of wings, both front and rear wings are membranous wings, and the mouthparts are piercing sucking. The body length is about 2.5cm. It is a relatively small cicada, with a purple blue color and black stripes. Its hind wings are black except for the edges, and it is widely distributed. It chirps from May to June, from morning till night, with a "chup chup" sound. Its call is not as loud as that of large cicadas such as black cicadas, and it is relatively fragile. Not as loud as large cicadas. There are also larger cicadas.
