One time, my father and I were walking in the countryside. A seven-spotted ladybug flew out of nowhere and landed on my shoulder. I wanted to crush it to death. At this time, my father quickly stopped me and said: "You can't hurt the ladybug, it is a beneficial insect!" I was very interested in the ladybug, so I quickly invited my little teacher, Shu.
It turns out that the seven-spotted ladybug is a type of carnivorous ladybug. It is less than 7 mm long and has an oval shape; its back is arched like a hemisphere, its head is black, and there are two light yellow spots on the top. The chest is black and densely covered with fine hairs. The elytra are red or orange-yellow with seven black spots on them, so they are called seven-star ladybugs. Despite its small size, it is a good predator of aphids, especially cotton aphids, wheat aphids, vegetable aphids and peach aphids. Someone has made statistics and found that a seven-spotted ladybug can eat an average of 138 aphids per day. Therefore, many agriculturalists use it to control insects.
I finally understood what my father said. We must protect the seven-star ladybug!
