Mongolian chills
Black grasshopper
Original title: Yangzhou black grasshopper cicadas the most: can be called the cicada "Mai Ba"
Just after the summer solstice, Yangzhou entered the "hot and humid" mode, although it was still raining non-stop, but as long as the sun came out and shook, the heat wave rolled in. In this heat wave, Zhiyi also began to let go of the "singing voice".
The more ferociously you scream, the longer you scream. In general, when the temperature reaches 26 ° C, the male cicadas begin to chirp. When the temperature reaches above 30 ° C, these male cicadas not only chirp longer, but also more often and make louder sounds. As a result, sometimes people can hear cicadas even at night.

In Yangzhou, black grasshoppers and cicadas are most commonly heard
From about 11 o'clock to about 14 o'clock yesterday, the reporter visited Yanfu Road, the ancient canal and other places, and heard the sound of cicadas along the way. Although the number is not very large, the loud sound is clearly recognizable, especially when there is sunlight, the loud sound is even louder. Most of the cicada sounds come from willow trees, and yellow cicadas can be seen on the trunks of willow trees.
Wang Min, deputy director of the Forestry Station in Hanjiang District, introduced that in Yangzhou, the most commonly heard cicada sound is from the black grasshopper, which is large and numerous, sometimes as many as dozens of cicadas on a tree. The black grasshopper can be called "Mai Ba", often a tight cry, continuously, seemingly never tired.
In fact, the often heard cicada sound is the cockroach, it is definitely the "sound idiot" in the cicada family, and will always emit only a single-syllable "zi". However, its chirping lasts very long, and its call can still be heard in autumn.
In addition, Mongolian cicadas are also more common, especially in the mountains after Yizheng such as Baiyang Mountain in Liuji Town, which is more common. Mongolian cicada, also known as a bug, has an undulating call and a low pitch, which can be called the "strength" of the cicada family.
Of the three common cicadas, the black grasshopper is "the boldest", while the Mongolian cicada is the most afraid of disturbing, and once someone approaches, it will stop singing.
The cicadas that chirp are all male cicadas
In Yangzhou, the most common place to hear or see cicadas is by the river. Because Yangzhou has a variety of willow trees along the river, the cicada family likes to choose to lay eggs in the willow treetops, and the larvae enter the ground after the eggs hatch.
Zhu Shude, a professor at the College of Horticulture and Plant Protection of Yangzhou University, introduced that the cicadas that sing are all male cicadas, they are actually attracting the attention of the opposite sex through singing, the louder the voice, the longer the duration, it means that the better it is, the higher the chance of getting love. Once married to the female, the male will die quickly.
The higher the temperature, the stronger the sunlight, the more cheerful it is
Zhu Shude said that the temperature and the intensity of the light affect the chirping of the know, the higher the temperature, the stronger the sunlight, the more ferocious they are, and the longer the chirping time. In general, when the temperature reaches 26 ° C, the male cicadas begin to chirp. When the temperature reaches above 30 ° C, these male cicadas not only chirp longer, but also more often and make louder sounds. As a result, sometimes people can hear cicadas even at night.
