Ciidae
Minute Tree-Fungus Beetles, Shelf Fungus Beetles
Ciidae, commonly known as minute tree-fungus beetles or shelf fungus beetles, are a family of small beetles within the superfamily Tenebrionoidea. Adults and larvae inhabit fruiting bodies of bracket fungi (Polyporales), particularly Polyporaceae and Corticiaceae, where they burrow inside the fungal tissue. The family is most diverse in warmer regions but has a cosmopolitan distribution extending to northern latitudes including Scandinavia. Development from egg to adult can occur in as little as two months, and some species are parthenogenetic. A few species, notably Cis chinensis, are recognized as pests of commercially dried fungi.
Hadreule blaisdelli
Hadreule blaisdelli is a species of minute tree-fungus beetle in the family Ciidae. Like other members of this family, it is associated with wood-decaying fungi, particularly bracket fungi (Polyporales), which serve as both habitat and food source. The genus Hadreule is part of a diverse group of small beetles that play specialized roles in forest decomposition systems.
