Sampsonius sexdentatus

Biology: 

Wood, 2007: This species is xylomycetophagous, domicile parasites of other ambrosia beetles. The critical factor in host beetle selection appears to be the diameter of the entrance hole of the host beetle tunnel. After the host beetle has established its tunnel in small diameter stems (about 3-8 cm in diameter), this species arrives and force entry (apparently using the large prothoracic spines), and evicts the original tenants, eggs, larvae and boring dust. It then produces its own brood in that appropriated tunnel.
