Sawtoothed Grain Beetle

Sawtoothed grain beetles (Oryzaephilus surinamensis) are very common commercial and household pests that will (like the flour beetles) feed upon cereals, pasta, nuts, and just about any other type of processed food. Adult beetles are small, (1/8 inch long) brown, somewhat flattened with six distinct “teeth” at the edge of the thorax (the segment just behind the head). A nearly identical species, the merchant grain beetle, infests the same types of foods, is found all over, but more commonly in warmer climates. So, how can you tell them apart if you don’t have fancy microscope? The merchant grain beetle can fly, but the sawtoothed grain beetle cannot.
