cryptophagids

Cryptophagids, commonly known as silken fungus beetles or minus beetles, are a family of small beetles belonging to the order Coleoptera. This family is characterized by their generally minute size, often measuring only a few millimeters in length, and their somewhat flattened, oval body shape. Their coloration can vary, but many are a dull brown or black. A notable feature of many cryptophagids is the presence of fine, silky hairs or scales on their bodies, which can give them a somewhat dull or matte appearance. The antennae are typically filiform or slightly serrated.

These beetles are primarily fungivores, meaning their diet consists mainly of fungi. They are often found in damp environments where fungal growth is abundant, such as decaying wood, leaf litter, under bark, and in compost piles. Some species are also associated with stored products, where they may feed on mold. Their life cycle involves egg, larval, pupal, and adult stages. The larvae are often cream-colored and grub-like, also feeding on fungi or decaying organic matter. Cryptophagids play a role in decomposition and nutrient cycling within their ecosystems.
