Armadillidium depressum, the southern pill woodlouse[1] is a large, relatively common British species of woodlouse characterized by its "splayed" appearance.

Description

Armadillidium depressum may reach a length of 20 millimetres (0.71 in) compared to 18 millimetres for Armadillidium vulgare, and is capable of rolling into a ball when disturbed. Like Armadillidium nasatum, it can be distinguished from Armadillidium vulgare by the gap it leaves when enrolled, instead of completely enclosing.[2][3] Another distinguishing feature is that its pleon curve outwards, causing a splayed appearance. Otherwise, the appearance of A. depressum is very similar to A. vulgare in dark grey to black color.[2][1]

Armadillidium depressum maximum length is 20 millimetres, compared to A. vulgare 18 millimetres.[2]

Ecology

Like other woodlice, Armadillidium depressum feeds on dead plant matter, and lives for 3 years.[1] A. depressum can be seen all year long.[1]

Distribution

The majority of specimens of Armadillidium depressum are concentrated in southwest Britain, near the English channel, but small populations also occur in various towns scattered throughout England.[2] It is a synanthropic species, living on walls and under stones in towns and old houses.[2][1]
