"on the tree by the pond, the sound of the summer is known." it's like we're talking about summer. The sound of a long or irritating sound opened up a summer。
And when they were little, they stood beneath a tree, facing their necks, looking for their faces. A little older brother will teach you to make simple nets of worms with poles。
See, ancient name is zen, and it's called zen, and it's a six-footed armen-insect syllable-syllable-syllable. The total number of animals in the general section of the sub-argument (now the nautilus) is now over 2,000. It means that the first pair of wings is the same as the second pair of wings (unlike beetle, locust, etc.)。
The standard shape of the sepsis: a broad head, a thick muscle-filled chest, two pairs of wings attached together, six short feet, and short and tight abdomen. They have a needle pipe-like stabbing mouth, which punctures into plant branches and feeds on plant juice。
Like many other insects that are not completely perverted, their lifetime is divided into three stages: eggs, worms and insects. Before the last decorating takes place, they live in darkness for a long time, often more than a year。
If the insect lives below the surface of the ground, it is fed by the sapling of the roots. In order to adapt to underground excavation life, if the insect's front foot is very strong (in the form of excavating foot), sharp teeth can help them to excavate in the soil. These worms live in darkness for a long time, often for more than a year, reaching the stage of maturity after several decorating, climbing out of the ground, “gold dehuming” on branches and turning into insects。
Most of them do not have a cycle, and if they receive enough nutrients from the roots of the plants under the ground or from the rods near the ground, they climb to the trunks in spring and summer. Then mate, lay eggs, die, live a lifetime. This is most of the life we've seen. In north america, there is a kind of insect that lives under extremely regular conditions for 13 or 17 years, and then, as if they were recruited, on a few weeks of summer nights, tens of millions of individuals break out of the ground, complete the final stages of their lives in a wave of mountain and tsunamis, then die and disappear until the next 13 to 17 years later. Because of these characteristics, they are called “cyclical”。
Scientists on this phenomenon have two main views, which may be caused by bad weather or predators of natural enemies。
It's the most vocal insect in the world. The noise is even more disturbing, given that it attracts the spouse。
The sonic sound is the male, and its pronunciator is at the base of the abdomen, like the drums that are covered with a drum, the drums are vibrated and the placards and drums are empty and resonant, so their sound is loud. The female musical instrument is not fully structured and cannot speak, so it is "mute."。
If you catch a whirlwind in the summer and hold their abdomen gently with your fingers, you find it amazing that they will stop screaming。
