It is a pest that sucks plant sap, and before molting it is black and wingless. The "flower big sister," the ladybug and the tree of heaven stink bug are three kinds of insects.

Beneficial insects, whether larvae or adults, can eat pests such as aphids, scale insects and mites. These pests reproduce and grow on the stems and leaves of plants, sucking the sap of the plants, causing flower buds to drop and fruit to decrease, and the yield and quality of crops are seriously affected. Ladybugs find places where pests such as aphids are dense and eat the aphids one after another. A single ladybug can eat more than a hundred aphids a day on average. Its larvae are also experts at eating aphids, and using ladybugs to control pests has a long history.
