Trachelipus rathkii

This european native species is often mistaken for Oniscus asellus or Porcellio scaber.  The smoother shell and 5 sets of white lungs underneath set them apart from both species.  T rathkii range from a calico yellow or orange to a darker grey.  Smaller than  laevis and typically showing at least a faint line of lighter dash marks above the lower edge of the shell.
