I found out why dragonflies can write with water.

That afternoon, my mother took me to play in Hualian Square. It just rained the day before, and the water on the ground is still wet. There are many dragonflies dancing in the air. I was immediately attracted, only to see them like a small helicopter, sometimes hovering over the pond, sometimes swooping down, gently touching the water with the tail tip, and the water surface would be rippled in circles. It is in response to Du Fu's poem-wearing a butterfly is deeply seen, and a dragonfly flies slowly with water. Is the dragonfly playing ballet or playing games in diving? This puzzled me. I asked my mother, but she let me find the answer myself. Find it yourself. I'm not afraid. When I got home, I quickly opened the book 1, Why, but there was no answer on it. I was unwilling to look for the answer from the encyclopedia Qian Qian Q again, and finally solved my doubts. It turns out that dragonflies are neither dancing nor playing, but laying eggs in the water. The larvae hatched from eggs, called hydra, can eat the eggs of mosquitoes that also lay eggs in water, or are they beneficial insects!

what a great discovery this time. I not only know the secret of dragonflies, but also know that the young eggs of dragonflies eat the young eggs of mosquitoes in the water. This incident also gave me a revelation: as long as you observe nature carefully, you will find many secrets.
