Opilo domesticus

This beetle can often be found in a loft where wood-boring beetles are attacking the timber. The adult beetle kills and eats many of the adult wood-boring beetles while its larvae hunt the larvae of wood- borers and house longhorns in their own tunnels. In doing so they have to dig their way through wood dust and in true mole fashion they eject this material through the exit-holes forming little ‘mole-hills’.
