They are called ladybugs or lady beetles in America. There are more than 5000 ladybird species. Ladybirds usually eat plant lice. However, Asian species when introduced to the Europe attacked European ladybirds. Dots on the ladybirds have nothing to do with the years of living. Some ladybirds have up to 22 dots on the back. Average lifespan of these cute bugs is three years. Some people believe that ladybirds can predict the weather. If they fell off your hand it would rain, if they flew away it would be fine. In Europe there are 6 spots in domestic ladybirds. However, there is a wide spread of yellow ladybugs introduced from Asia and United States. These bugs produce toxin that kills more lice than regular ladybugs, but these toxins can also be very harmful to those allergic to this toxic substance. There are conspiracy theories suggesting that these bugs were genetically developed to kill more lice on the crops. In any case domestic ladybirds are not immune to these toxins and their existence is questioned by many scientists.
