A globally widespread family of hemispherical, airworthy beetles, the cover wings of which usually have a different number of conspicuous points. The most significant species is the seven-spot ladybird (Coccinella septempunctata) because of its predatory performance against pests. But there are numerous other types with 2, 4, 5, 7, 10, 11, 13, 14, 16, 17, 18, 19, 22 and 24 points. The five to eight millimeter seven-point ladybird (also beetle or lucky beetle) is red to red-yellow to black and has seven black spots on both wings. After wintering as a beetle, the animals leave the roosts from the end of March and from the end of May lay yellow, oval 1.3 mm eggs in the cracks of piles. In June, the active larvae colonize the leaves of the vines. The development in mostly only one generation per year runs from the egg to four larval stages, the pupa to the sex animal; The larvae and the adult beetles are predatory.
