Image of FLAT GRAIN BEETLE
Cryptolestes pusillus 
Length: Approximately 2 mm
Minute, flattened, oblong, reddish-brown beetle, with elongate antennae about two-thirds as long as the body. One of the smaller beetles commonly found in stored grain. It follows up the attack of the more vigorous grain pests and is frequently found in enormous numbers with the rice weevil. This insect is a scavenger and often infests grain and meal that are in poor condition. The larvae are fond of the wheat germ, and, in infested grain, many kernels are found uninjured except for the removal of the germ. Larvae also feed on dead insects.
