Xyleborini classification
Sampsonius ensifer
EOL Text
Wood, 1982: Specimens were taken at ground level from stems 3-5 cm in diameter and from tree branches of similar diameter. The main adult gallery consists of a radial entrance tunnel and a transverse biramous gallery that follows a growth ring, in both directions, thus forming an almost complete ring around the stem about 1 cm below the surface of the wood. Rabaglia et al. 2006: This species is common and widely distributed in the eastern United States. It is among the larger species in the tribe in North America.

Wood, 2007: This species is xylomycetophagous and inbreeds polygynous. They breed mostly in unthrifty, injured, or cut stems larger than 3 cm and apparently smaller than 10 cm in diameter.

Wood, 1982: Specimens were taken from a dying mangrove tree 20 cm in diameter. The galleries are multibranching and usually penetrate the sapwood of the host. They may also form shallow tunnels that are visible on the surface of the wood from which the bark has been peeled. Wood, 2007, general comment on Xyleborus spp.: Felled, broken, damaged, and unthrifty stems ranging in diameter from about 3 cm to more than 3 m are selected for attack. In broken or felled stems the attack may be massive and encompass most or all of the sapwood within a few days. The galleries are usually of a simple branching type that may join other similar galleries of the same species. Eggs are usually placed in clusters at or near the end of branch tunnels. The larvae feed on the mycelium of ambrosial fungi, then pupate in these galleries. The brood emerges from the parent entrance tunnels.

Rabaglia et al. 2006: In North America, this species is similar to A. tachygraphus, but it can be distinguished from that species by the smaller size and the coarse, deep punctures on the elytral disc.
