近日,从美国东部到西部的伊利诺斯,数10亿长着红眼睛的蝉开始钻出地面。这些蝉的幼虫在地下依靠吮食树根生活了17年,而在钻出地面成为成虫后,它们仅仅能生存几周的时间。在这短暂的几周时间里,它们将放纵地呜叫、交配、产卵,然后迅速死去。这种蝉的蛹虫从地洞里钻出,然后爬到附近的树上脱皮,蜕掉硬皮, Recently, from Illinois to the west of the United States, a billion red-eyed crickets began to drill. These stingy larvae relied on the roots of the foraging tree for 17 years, but after drilling the ground to become adults, they only survived for several weeks. For a short period of several weeks, they will indulge, mate, spawn, and die quickly. This kind of burrowing locust drills out of the hole and then climbs to the nearby tree to peel off and crush the hard skin.
