context_page_description: Coccinella septempunctata, the seven-spot ladybird, 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.
context_section_description: C. septempunctata has a broad ecological range, generally living where there are aphids for it to eat. and including, amongst other biotopes meadows, fields, Pontic–Caspian steppe, parkland, gardens, Western European broadleaf forests and mixed forests. 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. It has been designated the official state insect of five different states (Delaware, Massachusetts, New Hampshire, Ohio, and Tennessee).
  Although C. septempunctata is mainly aphidophagous it also feeds  on Thysanoptera, Aleyrodidae, on the larvae of Psyllidae and Cicadellidae, and on eggs and larvae of some beetles and butterflies. There are one or two generations per year. Adults overwinter in ground litter parks, gardens, and forest edges, of treelines,  and under the tree bark and rocks.
  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. Massive swarms of C. punctata took place in the drought summer of 1976 in the UK. The species has undergone significant declines on the island of Malta, yet it is unclear whether this decline has occurred at the same rate elsewhere.
