Woodlice belong to the class of arthropods known as crustaceans, which is a predominantly aquatic group containing the crabs and lobsters. Although they now live on land the woodlice have not completely shaken off their aquatic habits. Their skins are not completely waterproof, and the animals very soon desiccate in a dry environment. This is why almost all of them are confined to damp places and why they only come out to feed at night, when the air is cooler and damper. Many of the species can breathe only if their bodies are covered with a thin film of moisture, although they would soon drown if immersed in water...too much of a good thing.!

Answer 2

"Woodlice need moisture because they breathe through gills, called pseudotrachea, and so are usually found in damp, dark places, such as under rocks and logs. They are usually nocturnal and are detritivores, feeding mostly on dead plant matter. Woodlice then recycle the nutrients back into the soil. In artificial environments such as greenhouses where it can be very moist, woodlice may become abundant and damage young plants, such as ferns."
