When the cells are ready, they start moving toward the top of your epidermis. This trip takes about 2 weeks to a month. As newer cells continue to move up, older cells near the top die and rise to the surface of your skin. What you see on your hands (and everywhere else on your body) are really dead skin cells.
Most ladybugs are predators. They eat other insects, most of which are considered pests to humans who like to grow plants for food or beauty. They are often called a gardeners best friend. The most common insects that ladybugs eat are aphids, which are serious pest of plants. Thats why ladybugs can be the gardener's best friend. They will control the pest insects in the garden without the gardener having to use chemical pesticides. Even larval ladybugs eat aphids.
Having a ladybug land on you can be a magical moment. While other insects may pose a threat to humans, animals and crops alike, ladybugs are harmless -- and even better, they're beneficial! That's why so many cultures over the centuries have cherished ladybugs, believing them to bring good luck.armers encourage ladybug populations in their fields because ladybugs protect crops from insects, especially from aphids and other sap feeders who can do great damage. A single ladybug can eat as many as 5,000 aphids in its lifetime, according to the University of Kentucky Department of Entomology.
