Xyleborus celsus
Wood, 1982: Evidently logs and stumps are attacked. According to Hubbard (1897) the gallery system is deep in the wood, with a palmate branching of tunnels from the end of the radial entrance tunnel. Rabaglia et al. 2006: This relatively large and slender species is distinguished from other North American Xyleborus by the steep, flat declivity with large tubercles and the very wide declivital interstriae 1. This species seems to be restricted to hickories (Carya spp.). It can attack weakened trees but usually causes damage to cut logs (Solomon 1995).
