Description:

Found in a chunk of fallen elder. My guess is that there are two species visible here - one dark and rough (Porcellio scaber?), the other with a green/black pattern. Can anyone confirm?

Two species

Looks like there are a couple of Oniscus asellus (Common shiny woodlouse) in there as well.

Yes, two spp., also two

Yes, two spp., also two colour forms of P. scaber: the largest mottled one just left of centre looks like the pale form of scaber. Top left and the one arching its back bottom middle look like Oniscus asellus.
