( Latin: Acanthomyops fuliginosus )
These shiny, black ants normally live in trees, and they have a distinct smell of oranges. They can establish themselves in the dead parts of trees, in stumps and in wooden floor boards damaged by damp.
They gnaw extensive tunnels and holes in the timber, and they fill them with a dark papery material which they make by mixing gnawed wood fragments with saliva and particles of earth or other available material. The timber these ants live in need not necessarily be damaged by moisture, and sometimes they spare the harder parts so that the summer wood remains as lamellae. When present in a house, there will usually be ceaseless troops of these ants moving in line between their nest and food sources in the kitchen.
