When did cicadas come out? It's mid-July, and we're going to beginning of autumn in August! Why didn't I hear cicadas singing here in summer? Isn't that strange?

Cicada comes out from late spring to late summer.

Cicada's appearance time:

Late spring: fly [Hu Wei];

Summer solstice: black cicada;

In the middle and late stage of incubation, it is [diā o liá o];

Dormant in late summer: Wu Xun [w ti á o];

The cicada that can sing is a male cicada. Its vocal organ is at the base of the abdomen, covered with an eardrum like a drum. The eardrum vibrates and makes a sound. Because the vocal cord muscles can expand and contract about 65,438+0,000 times per second, and the gap between the cover plate and the eardrum can play a role of * * *, its singing is particularly loud. And you can sing in different tones in turn. The female cicada is a "dumb cicada" because her musical instrument structure is incomplete and she can't make a sound.

Cicada is the feeling of summer. Cicadas often appear in places with many trees. If you don't hear cicadas, you can go to a nearby park and you should be able to find them.
