Southern Pill Woodlouse - Armadillidium depressum

Description

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.
