There is also a thin layer of soft wings under the sheath, which can fly.

Ladybugs are mainly beneficial bugs, but there are also a small number of pests. Common beneficial bugs: two-star ladybug, six-star ladybug, seven-star lady beetle, 12-star lady beetle, 13-star lady beetle, red lady beetle, etc., 11-star lady beetle and 28-star lady beetle are all pests. Beneficial insects, whether larvae or adults, can eat pests such as aphids, Jieke insects and ticks. These pests reproduce and grow on the stems and leaves of plants, sucking plant juice, resulting in the loss of buds and fruits, and the yield and quality of crops are seriously affected. Ladybugs find places where aphids and other pests are dense and eat aphids one after another. On average, a ladybug can eat more than a hundred aphids a day.
