Saw-Toothed Grain Beetle

 

(Oryzaephilus surinamensisi), a beetle of the family Cucujidae. The body, which is 2.5–3.5 mm long, is elongated, flat, and red-brown. The prothorax has dentate edges and two grooves on the upper side. The insect is ubiquitous. It often lives in warehouses. The beetle and its larvae spoil flour, groats, grain (that has already been damaged by other pests), and dried fruits and vegetables (most often moldy ones). The saw-toothed grain beetle bears four or five generations per year in the south and two or three in the north.
