Worldwide spread family of hemispherical, flyable beetles, whose cover wings usually have a different number of conspicuous points. The most significant species is the seven-spot ladybug (Coccinella septempunctata) for its predatory performance against pests. But there are many 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 ladybug (also known as God beetle or lucky beetle) is red to reddish-yellow to black and has seven black spots on each of the upper wings. After hibernating as beetles, the animals leave the neighborhoods from the end of March and lay yellow, oval 1.3-millimeter-sized eggs in cracks of stakes from the end of May. In June, the active larvae mainly colonize the leaves of the vines. The development in usually only one generation per year runs from the egg on four larval stages, the doll to the sexual animal; predatory are the larvae and adult beetles.
The insect is one of the most important in viticulture beneficials, which is also used purposefully. Depending on size are considered prey animals aphids (in the picture below), mites, smaller ones tracked. Rebenschmierlaus. Rebenthripse. psyllids. Scale insects and cicadas consumed - both the insects themselves and their larvae and eggs. With enough supply, they eat up to 50 per day and several thousand during their lifetime. 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 the Asian ladybugs (also multi-colored ladybird), which occurred first from the year 2001 on the east coast of the USA.

The picture shows some Asian ladybugs hunting black bean aphids. In the video clip (click to view) a larva of the ladybird can be seen, which also consumes aphids. See also a complete listing of all diseases and pests below Vine enemies,
