The representative species of cicadas. The male's abdomen has a sound generator, which can constantly make sharp sounds. The female doesn't make a sound, but she has a hearing device in her abdomen. Larvae live in the soil, suck the roots of plants, and adults eat the juice of plants. Cicada is an incomplete metamorphosis, from egg and larva (nymph) to adult after several molts without pupa. In the words of Zen in Buddhism.

In recent years, the phenomenon of catching golden cicadas in restaurants in Shandong, Shanxi, Henan, Hebei and Anhui is very serious. Because the golden cicada larvae live underground for about 5- 12 years before they can break out of the ground, the number of golden cicadas has dropped sharply because of such crazy capture. In some areas, cicadas can no longer be heard in summer, and the golden cicada is facing a crisis of survival and may even become extinct!

Cicada, also known as cicada, cicada, cicada monkey, cicada monkey, cicada monkey, turtle, fairy or cicada turtle, is a medium to large insect of the same order, with about 2000 species. It is 2 ~ 5 cm (0.8 ~ 2 inches) long, with two pairs of membranous wings, prominent compound eyes and 3 monocular eyes. There are two species of Cicadellidae, commonly known as Cicadellidae, which are only distributed in southern Australia.

breed

Cicada eggs are usually laid in woody tissues. Once hatched, the nymph burrows into the ground and sucks juice from the roots of perennial plants. Generally, after molting for 5 times, it takes several years to mature. When the number of female insects is large, the oviposition behavior will damage the young trees.

Be distributed

Cicadas are mostly distributed in tropical areas, inhabiting deserts, grasslands and forests. In addition to the LEPIDOPTERA species that appear every summer, there are periodic cicadas. The most famous periodic cicadas are 17 cicada and 13 cicada, which appear in a certain area at regular intervals.

Some species are easy to distinguish in singing, behavior and morphology. Male cicadas of each species make three different songs: collective songs, which are regulated by daily weather changes and other male cicadas; Courtship before mating; The harsh sound made when caught or afraid to fly away.

Larvae live in the soil and suck the juice from the roots of plants, while adults suck the juice from the upper parts of plants.
