There are lovely words for woodlouse actions too: an animal rolling its body into a neat ball is known as conglobation, or volvation in zoology.<\/p>\n
Their nicknames reflect our fondness for this most accessible of isopoda, an order of crustaceans, which is found in houses and gardens across Europe and the US.<\/p>\n

The common rough woodlouse, Porcellio scaber, is more widespread and found in South America and Australia too but it does not curl up in a ball. Hopefully, woodlouse voters in all continents can set aside their love for their local representative and consider the common woodlouse to stand for the entire 5,000-species-strong suborder.<\/p>\n
The woodlouse was a trendsetter, its ancient ancestors moving on to land about 500m years ago, long before most animals. The woodlouse hasn\u2019t needed to make many design refinements over the years because it found such a useful niche from the start. As a detritivore, it feeds on rotting plant matter and breaks down wood.<\/p>\n
Sally Roe, one of many Guardian readers to nominate the woodlouse, has a good story. When she installed biodegradable bamboo kitchen countertops, she used an offcut in the garden to weigh down the cardboard suppressing weeds in her pumpkin patch. After a (successful) harvest, she moved the solid slab of bamboo and found a large colony of woodlice underneath. \u201cThe formerly very solid, very heavy slab of bamboo worktop was now a paper-light wood honeycomb,\u201d she says. \u201cWoodlice demonstrated to me extremely clearly that something being \u2018biodegradable\u2019 relies heavily on invertebrates.\u201d<\/p>\n
As well as tidying up our world, another of the woodlouse\u2019s superpowers is its ability to withstand toxic pollution and even store heavy metals within special compartments in its body. Studies have shown it can help stabilise heavy metals in compost<\/a>.<\/p>\n A common pill woodlouse (Armadillidium vulgare), another of the many types of woodlouse \u2013 this one commonly found in Europe and familiar to many of us.

Chris Pickard is consoled by their longevity. \u201cThey will undoubtedly be here long after humans have followed dinosaurs and dodos into the extinct category,\u201d he says.<\/p>\n
