Cleroidea

thumb|Anthocomus rufus ([[Melyridae)]] thumb|Airora cylindrica ([[Trogossitidae)]] Cleroidea is a small superfamily of beetles containing over 10,000 species. Most of the members of the group are somewhat slender, often with fairly soft, flexible elytra, and typically hairy or scaly.

Byturidae, also known as fruitworms, are small family of cleroid beetles with over 15 described species, primarily distributed in the Holarctic and Southeast Asia. The larvae of at least some genera feed on fruit, such as Byturus, a notable commercial pest of Rubus (blackberries and raspberries) consuming both the fruit and seeds, while others like Xerasia are associated with catkins. The adults are known to feed on developing leaves, flowers and pollen.

Biphyllidae, or false skin beetles, are a family of beetles, in the superfamily Cleroidea. They have a cosmopolitan distribution (excluding New Zealand). About 195 species are known. They live under the bark of dead trees and in leaf litter, and are mycophagous, feeding on fungi.
