Common striped woodlouse (Philoscia muscorum)

18 November 2018

Philoscia muscorum, the common striped woodlouse or fast woodlouse

This medium sized species (to 11mm) with a stepped body outline bearing a distinctive dark dorsal strip, runs rapidly when disturbed.  The antennae have three flagella segments and it lacks pleopodal lungs.

Confusion is most likely with Ligidium hypnorum (flagella of numerous bead-like segments) or Porcellionides cingendus (flagella of two segments, plus two pairs of pleopodal lungs). Orange colour forms have been mistaken for Androniscus dentiger.

It has recently become apparent that a second species of Philoscia - P. affinis - also occurs in Britain.
