Since circumstellar dust in debris disks is short-lived, dust-replenishing requires the presence of a reservoir of planetesimals which continuously supply the disk with fine dust through their mutual collisions. In this talk I will summarize selected studies related to the properties of this dust and the structure of debris disks on various scales.
