what is it?

Lasius brunneus is a species of ant in the genus Lasius . The species is widely distributed in Europe, from Sweden in the north to Anatolia in the south. In England this species is almost always found nesting in oak trees or rotting wood mainly foraging in trees but has also been found under stones and foraging on the ground. It is thought to be underrecorded but is fairly common especially in the South East.
