fast moving and well marked Woodlouse, Philoscia
muscorum is usually found in well vegetated, grassy sites and is very common in most of the
county's woodlands. It regularly occurs in suburban parks
and even gardens.
There is potential confusion with Philoscia affinis
Verhoeff, 1908, which has not yet been recorded from
Nottinghamshire, but which is extremely similar in
general appearance to Philoscia muscorum. The
pigmentation of the head and body is a reasonable
identification guide to separating the two species, but
reliable identification requires microscopic examination
of a male specimen.
