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.
The insect is one of the most important in viticulture beneficials, which is also used specifically. Depending on the size, they are considered prey aphids (in the picture below), mites, smaller tracked. Rebenschmierlaus. Rebenthripse. psyllids. Scale insects and cicadas consumed - both the insects themselves and their larvae and eggs. If there is enough, they eat up to 50 pieces a day and several thousand during their life. The beetles are therefore bred for biological pest control. Some species (22- and 16-point) feed exclusively on the mildew, Unfortunately, this does not play a role in combating these fungal diseases. A dangerous type in viticulture is that Asian ladybug (also multi-colored ladybug), which first appeared on the east coast of the USA in 2001.

The picture shows some Asian ladybugs chasing black bean aphids. In the video clip (click to view) you can see a larva of the ladybug, which also eats aphids. See also a complete listing of all diseases and pests below Vine enemies,
