The seven-spot ladybird, scientifically known as Coccinella septempunctata, is a species that primarily feeds on aphids but also consumes other insects such as Thysanoptera, Aleyrodidae, Psyllidae, Cicadellidae, and the eggs and larvae of certain beetles and butterflies. They breed once or twice a year and hibernate in various locations such as ground litter, tree bark, and rocks. Their ecological range is broad, encompassing meadows, fields, forests, and other habitats where aphids are present. However, in the UK, there are concerns that the harlequin ladybird is outcompeting the seven-spot ladybird for food. These ladybirds have distinctive spots and bright colors that serve as warning signals of their toxicity to predators. They can secrete a foul-tasting fluid when threatened and may also play dead for protection. The size and coloration of their spots can indicate the level of toxicity they possess. Coccinella septempunctata can be found in various regions globally, including Europe, North Africa, Australia, and Asia.
