Coccinella is the most familiar genus of ladybird (or, in North America, ladybug). The elytra of most species are of a red or orange colour, punctuated with black spots or bands. The genus occurs throughout the Northern Hemisphere, but has only 11 species native to North America, with far more in Eurasia.
Its name comes from Latin coccineus, referring to the color scarlet.
Adults and larvae are voracious predators of aphids, and some species (e.g. Coccinella septempunctata) are used as biological control agents.
