Summer is here, and with summer come the world’s noisiest insects. You can hear cicadas everywhere you go in Nagoya these days. They come out after the rainy season, but where do they come from? Young cicadas go underground after they are born. They stay underground for a few years before they come out of holes under trees. These young cicadas are called nymphs. When they climb out of the holes, they climb up a nearby tree. Then, at night, they leave their outside shell and become adults. You can find the empty shells on the trees right now. The male cicadas are the noisy ones. They make noise to attract female cicadas.   (113 words )
