The species is an invader that is quickly colonising Britain. It was first seen in the Uk in October 1999 beside a reservoir in the Lea Valley, Essex. The species has been expanding northwards from Italy, austria and Switzerland. Where it is has colonised Denmark and Germany, it has displaced the other two species of Opilio so this may also happen here.
