Latin name: Porcellio scaber
Size: Up to 17mm
Distribution: Found throughout the U.K.
Months seen: All year round
Habitat: Damp, shaded places such as under stones and logs
Food: Dead plant matter
Special features: Probably the commonest species of woodlouse found in the UK, sometimes even showing up in houses.
The common rough woodlouse is usually grey in colour, but can be mottled with yellow or brown. When viewed under a hand lens you'll see where the "rough" name comes from. The upper surface is covered in bumps.
If you turn the creature over you'll notice it has two pairs of lungs, which appear as white patches near the tail end.
The end of the antennae (the Flagellum) is in two segments. The eyes are composed of a group of shiny black bumps (called 'ocelli').
