Several species of Ladybird Beetles (often called 'Ladybugs') come into humans' houses to "diapause" over the Winter. The Asian Ladybird Beetle is one of the more common ones that does this throughout much of the U.S. Even though ladybugs can be quite beautiful, they can also become quite a nuissance in large numbers.
