Cerylonidae

The Cerylonidae family, commonly known as minute cypress bark beetles, are a group of approximately 500 species of beetles belonging to the order Coleoptera. These insects are characterized by their small size and narrow, flattened bodies, which are typically red, yellow, or brown.1

Minute cypress bark beetles are found worldwide and are generally less than 13 mm (0.5 inches) in length. They are primarily predatory, feeding on mites and small insects. Some species within the genus Catogenus are known to parasitize the larvae of long-horned beetles and certain parasitic wasps. While most Cerylonidae are beneficial predators, a few species, like the saw-toothed grain beetle and the rusty grain beetle, can be significant pests of stored grain.1
