The seven-star ladybug has a strong self-defense ability. Although its body is only as big as a soybean, many powerful enemies are helpless against it. There is a kind of "chemical weapon" on the joints of its three pairs of thin legs. When it is attacked by an enemy, its foot joints can secrete an extremely unpleasant yellow liquid, causing the enemy to retreat hastily because it can't stand it. escape. It also has the ability to pretend to be dead. When it encounters a strong enemy or danger, it will immediately fall from the tree to the ground, shrink its three pairs of thin legs under its belly, lie down pretending to be dead, and survive by hiding from the enemy.
