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.

Description

Cleroidea is defined by the following features: adult and larva with mandibular mola absent, larva with basal mandibular process (lacinia mobilis) present), and mala with a pedunculate seta present.

Some cleroids, especially in Cleridae and the melyrid subfamily Malachiinae, have bright aposematic colouration to deter predators. They mimic the appearances of other arthropods that are unpalatable to predators, such as various beetles (blister beetles, leaf beetles, net-winged beetles), stinging Hymenoptera (ants and velvet ants), zygaenid moths and tachinid flies.

There is variation in the degree of sclerotisation within Cleroidea. Some are hard-bodied beetles with fully sclerotised elytra that match the shape of the abdomen (Trogossitidae, Lophocateridae, Peltidae). The melyrid lineage (a group including Melyridae and other families) and the two small families Phloiophilidae and Acanthocnemidae are highly soft-bodied. The Cleridae are intermediately soft-bodied.
