Known for its unique appearance, the female can be up to 15-18cm long, covered with thorn-like thorns, and has a variety of colors, including brown, green, yellow and white. The male is small, about 12-13cm, with well-developed wings and capable of flight.

Usually between 1 and 10 millimeters in length, the body is round or oval in shape, with a variety of colors ranging from bright red, orange to black, dotted with black or white spots. Known for preying on pests, especially aphids, it is an important beneficial insect in agriculture and horticulture. The life cycle of ladybugs includes four stages: egg, larva, pupae, and adult. Their eggs are usually yellow in color, and after hatching, the larvae will prey on small pests such as aphids. As the larvae grow, they undergo several molts and eventually form pupae. Adult ladybugs have the ability to fly.
