Is the cicada an insect?

Cicadas are insects. Belonging to the family Cicadellidae of Insecta, it is a kind of incomplete metamorphosis insect, which goes through three stages: egg, nymph and adult. In life, we also call it cicada, loaner, and so on.

2. The development of cicadas

The cicada is an incomplete metamorphosis insect. It has no pupal stage. When summer heats up, eggs laid in previous years hatch larvae, which drill into the soil and feed on the sap of plant roots. It takes about five years to live, and when it matures, the larvae climb to the ground, begin to molt and become adults. Adult cicadas can only survive for a few months.

Third, the vocal principle of cicadas

The cicadas we hear in our lives are all made by male cicadas, and their speakers are at the base of the abdomen, how a big drum. The tympanic membrane is vibrated to make a sound, because the tympanic muscle can stretch about 10,000 times per second, and there is an empty space between the cover plate and the tympanic membrane, which can resonate, so its sound is particularly loud. And can take turns to sing in different tones. If the structure of the female cicada is incomplete, it can not make a sound.

As an insect, cicadas can be used as medicine, and cicadas are nutritious and edible. If you are interested in it, you can taste it.
