There are twelve Bin Weevil families altogether, and usually most of the weevils in the family have identical or similar appearances, but have different personalities and have the same endings in their names. It is sometimes, but not always, true that the family is named after the second most famous weevil within it. This affect can be observed in the Rott, Ink, Punt, Flem, Tab, Kip, Rum and Bing; although it falls apart for the Dosh, Flem and Gong families.
