Toothed Grain Beetle
The adult Toothed grain beetle is a small insect, no more than 2.5 mm to 3 mm long, having a light red to reddish-brown colour. The serrated grain beetle looks very similar to the Confused Flour Beetle, except for 6 sawtooth-shaped appendages on each side of the thorax.
The Toothed grain beetle feeds on a wide variety of foods that include cereals, bread, pasta, dried fruit, flour, cookies, powdered desserts, such as cakes and some spices.
We find the Toothed grain beetle in supermarkets and other food stores from which they will be introduced into our homes with groceries. This flat-bodied insect can sneak into poorly closed and/or poorly sealed bags.
The female lays 45 to 300 eggs, randomly in food or in packages in a crack of damaged grain.
