Southern Pill Woodlouse - Armadillidium depressum
Armadillidium depressum is a dark grey to black species and may reach a length of 20 millimetres. It is very similar to Armadillidium vulgare (which may reach 18 millimetres). Both species are capable of rolling into a ball when disturbed but Armadillidium depressum can be distinguished because it leaves a gap when enrolled, instead of completely enclosing like Armadillidium vulgare. Another distinguishing feature is that its pleon curve outwards, causing a splayed appearance.
Found under stones and logs, also in old buildings etc.
All year round.
Feeds on dead plant matter, and lives for 3 years.
Mainly recorded in southwest Britain, near the English channel, but small populations also occur elsewhere throughout England.
Rare or under recorded in Leicestershire and Rutland.
