Cryptophagidae

a family of small beetles that measure 1–5 mm long and usually are yellow or brown in color. The antennae are club-shaped. The insects, which live in decaying plant remains and under bark, feed on a variety of lower fungi. Of the approximately 2,500 widely distributed species, about 200 are found in the USSR. Some species are crop pests: for example, the beetle Atomaria linearis injures the seeds, shoots, and roots of beets and turnips.
