Often charmingly referred to as the Roly-Poly; Armadillidium vulgare, is originally native to the UK and other areas of Western Europe (France, Germany, Belgium, Spain etc) but is now present almost completely worldwide. Their adaptable and exceptionally hardy nature has led to them colonising any climate: cold, temperate or tropical; and habitat: desert, forest, coastline etc. Unlike many other Armadillidium species; vulgare are not aggressive protein eaters and will readily consume soft bodied plants.

Despite their cosmopolitan nature they do have preferred requirements in which they seem to grow and reproduce at the healthiest rate. Though this species has been seen to tolerate temperatures as low as −1°C, all the way up to over 30°C it does best kept at a temperate 20 to 24°C. They prefer a semi-arid environments with humidity on the lower side, around 60%. If kept at high tropical humidity for long periods they can have issues moulting.

The Common Pill Woodlouse (Armadillidium vulgare) is a relatively large species growing up to 18 mm body length. Usually a slate grey colour overall, it can be highly variable in both colour and pattern, which has lead to selective breeding of this species in order to isolate the different colours.

‘Magic Potion’ is a colour morph of A. vulgare that occurs in nature though very rarely; it has been isolated and selectively bred in captivity due to its attractive appearance. Magic Potions have increased yellow markings on their back that are more brightly coloured than the standard wild type; this is on a semi-transparent whiteish background rather than the typical grey. Confusingly the ‘Magic Potion’ morph is also present, and under the same name, in two similar species: A. depressum and A. granulatum.

We do also offer this species in a mixed colour variety and in the wild type natural form.

Sold in a tub of 10.
