(Tenebrioides mauritanicus), a beetle of the family Tenebrionidae. Length, up to 11 mm. The beetles have dark brown backs and rusty yellow abdomens. The larvae reach 20 mm in length and are flattened in shape and dirty white in color.
The cadelle is found in countries with warm climates and inhabits the southern regions of the USSR. It lives in mills, grits and bread-baking plants, and granaries; in the wild it is found under the bark of old and dead trees. The beetles and larvae damage flour, grits, grain, and confectionery goods. They do some good by eating the larvae and pupae of harmful insects. Cadelles can gnaw through the silk screens of crop sowings and destroy the wooden parts of dwellings and implements. Control measures against grain pests are followed for the cadelle.
