The lifecycle of the varied carpet beetle starts as an egg. The larvae (known as the woolly bears) may moult over a dozen times, increasing in size each time. Upon the final moult its next life stage will be pupation. Pupation can vary in timing in relation to environmental causes & may well last over winter being ready to hatch out into adult form in the spring. Adult carpet beetles are expert aviators & will fly long distances to find suitable food & breeding sites.
