Common Woodlouse

'At last another crustacean!' I hear you cry. This time it's the larger cousin of the first to be featured on the blog. The common woodlouse, Oniscus asellus, is, oddly enough, the commonest woodlouse in the British Isles. It's also one of the largest. 
The pale yellowish spots on their backs are calcium storage areas. 
Moulting is a game of two halves: first the rear, then the fore. They usually eat the exuvia afterwards. Nice.
