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.
Epilachninae, a sub-species of ladybugs, are small round beetles that are orange-colored and spotted. They are considered to be the vegetarians of the ladybug world, since they eat fungi like mushrooms and mildew. Some even eat leaves.
The spotted red 'ladybug' we all know so well (more correctly called the 'lady beetle' or 'ladybird beetle', as these insects are true beetles and not bugs) does dine on the occasional aphid and other soft-bodied pest, but like many insects, it doesn't really eat all that much in it's adult form.
