Oryzaephilus mercator
Merchant Grain Beetle
A small, flattened beetle approximately 2.5–3 mm in length. A cosmopolitan pest of stored food products, particularly processed cereals and oilseeds with high oil content. Distinguished from the nearly identical Oryzaephilus surinamensis by its larger eyes and narrower head behind the eyes. Unlike O. surinamensis, adults are capable of flight.
