Coccinella septempunctata
''Coccinella septempunctata'', the seven-spot ladybird (or, in North America, seven-spotted ladybug or "C-7"〔(【引用サイトリンク】title=''Coccinella septempunctata'' (Linnaeus,1758:365). Seven-spotted lady beetle; Seven-spotted ladybug )〕), is the most common ladybird in Europe. Its elytra are of a red colour, but punctuated with three black spots each, with one further spot being spread over the junction of the two, making a total of seven spots, from which the species derives both its common and scientific names (from the Latin ''ラテン語:septem'' = "seven" and ''ラテン語:punctus'' = "spot").
== Biology ==
''C. septempunctata'' has a broad ecological range, living almost anywhere there are aphids for it to eat. Both the adults and the larvae are voracious predators of aphids, and because of this, ''C. septempunctata'' has been repeatedly introduced to North America as a biological control agent to reduce aphid numbers, and is now established in North America, and has been subsequently designated the official state insect of five different states (Delaware, Massachusetts, New Hampshire, Ohio, and Tennessee).
In the United Kingdom, there are fears that the seven-spot ladybird is being outcompeted for food by the harlequin ladybird. Conversely, in North America, this species has outcompeted many native species, including other ''Coccinella''.
