Rice Weevil
A tiny reddish-brown weevil with a long curved snout and four faint pale spots on its wing covers, commonly found infesting stored rice, wheat, and other grain products.
beetle
Confused Flour Beetle
A tiny, flattened, reddish-brown beetle commonly found in stored flour and grain products, distinguished from its near-identical relative the red flour beetle mainly by its antennae shape.
beetle
Clothes Moth
A tiny, pale golden moth that avoids light and flutters weakly from dark closets, more often noticed by the damage its larvae leave in stored fabrics than by the moth itself.
moth
Red Flour Beetle
A tiny, flattened, rust-red beetle found in stored flour and grain worldwide, capable of flight and closely resembling the confused flour beetle apart from the shape of its antennal club.
beetle
