The spicy smell from these juices can make people feel tired, and even birds will “run away” when they smell this strange smell. .

The “staple food” of the lady beetle is aphids. Ladybugs often crawl and search on the host plants of aphids. When their mandibles touch the aphids, they can quickly bite with their upper jaws and devour the aphids. If the mandible whiskers are not touched, even if the aphid is right in front of its eyes, it cannot be detected. The adult of a lady beetle eats 100-120 cotton aphids, 147 vegetable aphids and 59 apricot aphids a day on average. The amount of aphid larvae varies according to the size of the instar. When you are older, you eat less snacks, and when you are older, you eat more.
