brown shiny carapace with lighter mottling and a pale edge
No interactions present.
The left-most is Philoscia muscorum and the large grey one at the right hand side of the left picture is probably Porcellio scaber.
I agree that the left-most is Philoscia muscorum , also a small immature Philoscia below this, and the large grey one at the right hand side of the left picture IS Porcellio scaber.
