Oryzaephilus mercator, the merchant grain beetle, is a small, flattened beetle about 2.5mm in length. [1] It is a common, worldwide pest of grain and grain products as well as fruit, chocolate, drugs, and tobacco. [1] The biology of O. mercator is nearly identical with Oryzaephilus surinamensis (the sawtooth grain beetle). [1]

Oryzaephilus is a genus of beetles in the family Silvanidae, containing 16 species: [1]. Oryzaephilus abeillei Guillebeau; Oryzaephilus acuminatus Halstead; Oryzaephilus breuningi Halstead
O. surinamensis is a slender, dark brown beetle 2.4–3 mm in size, with characteristic "teeth" running down the side of the prothorax. [4] It is nearly identical to Oryzaephilus mercator, or the Merchant Grain Beetle, [2] however, O. surinamensis has smaller eyes and a broader, more triangular head; [2] O. surinamensis unlike O. mercator are unable to fly.

HGRS87 also specifies a transverse Mercator cartographic projection (TM) with m 0 =0.9996, covering six degrees of longitude either side of 24 degrees east (18-30 degrees east). This way all Greek territory (stretching to approximately 9° of longitude) is projected in one zone.
Researchers from Mass General Brigham, a health care system in Boston, Massachusetts, shared with Fox News Digital some of the scientific developments and breakthroughs they expect to see in 2025.
The species is very similar to saw-toothed grain beetle, Oryzaephilus surinamensis and the merchant grain beetle, Oryzaephilus mercator. [3] Male is about 3.7 mm and female is about 3.5 mm in length. Adults are dark brown to black. Body is more elongate and covered with recumbent golden setae. Pronotum in large males.
