With this photo of a Common Woodlouse (also known as shiny or smooth woodlouse) Oniscus asellus, let me round up the topic of woodlice. Woodlice are crustaceans, a mostly marine group. They have 7 pairs of legs when adults. They are quite gregarious, and usually many individuals are found together. The common woodlouse is not as drought resistant as the rough woodlouse, as their bodies are more permeable to water, and therefore is present in more humid microhabitats. It has a very shiny cuticle with dark and light patches, although colour varies, their antenna are longer than in the rough woodlouse. We found these large individuals (this is the largest UK species and can reach 16 mm in length) today under large logs kept covered with some tiles.
