Oriental wood borer (Waterhouse)
Oriental wood borer (Heterobostrychus aequalis). This genus is about 6-13mm long in length and is reddish-brown to brownish-black in color. The head is not visible from above, as it is recessed beneath the pronotum. The anterior half of the pronotum has broad, toothlike marginal tubercles. The elytra have several rows of deep pits, and toward the rear the wing covers curive inward creating a concave area that in the males is equipped with two stout spines.
