Ladybirds, also called ladybugs or lady beetles, are small beetles of the family Coccinellidae. Recognised by their dome-shaped bodies and bright colours—red, orange, yellow, or black with spots—they occur worldwide in many habitats. They are valued for eating aphids, scale insects, and other plant pests, making them useful natural pest controllers for gardeners and farmers. When food is scarce, they may even eat their own eggs or larvae to ensure some offspring survive. Their presence usually signals a healthy ecosystem, and they have long inspired folklore, art, and cultural symbolism.
