Cryptolestes cornutus
Cryptolestes cornutus is a species of flat bark beetle in the family Laemophloeidae. The genus Cryptolestes comprises small, elongate beetles commonly found under bark and in stored products. Many species in this genus are recognized as pests of stored grain and cereal products. The specific epithet 'cornutus' refers to horn-like structures, though detailed morphological descriptions for this particular species are limited in available literature.
Cryptolestes ferrugineus
rusty grain beetle, rust-red grain beetle
Cryptolestes ferrugineus, the rusty grain beetle, is a small lined flat bark beetle and major cosmopolitan pest of stored grain products. Native to Europe, it has achieved worldwide distribution through human commerce, infesting stored cereals, grain products, and dry plant materials. The species is characterized by rapid population growth, strong flight capability for dispersal between storage facilities, and cryptic behavior hiding in cracks and crevices. Its economic impact stems from direct feeding damage to grain germ and endosperm, contamination of products, and resistance to some insecticides.
