Ladybug, despite the harmless look, predator. She eats low-mobility aphids - pests of plants. On the day this crumb kills almost a hundred aphids or three hundred of their larvae. One ladybug for her life lays about four hundred eggs. Each of them displays a larva, which also feeds on aphids. It grows and less than a month pupates. The dolly is glued to the leaves and hangs upside down. Soon from it comes an adult ladybug.
