Woodlouse – What is a woodlouse?

Definition of woodlouse

Brownish or greyish in colour and slightly elongated oval in shape, the woodlouse has seven pairs of legs and small, short antennae at the front. Since it prefers humid environments, it lodges under rocks and stones, under decaying plant debris, on which it feeds, and finds its way into the soil. If you find a large number of them inside buildings, it is usually a sign of an abundant presence outside. Egg laying occurs one to three times a year, except during the winter period, when they are inactive. The complete life cycle of the woodlouse can last up to two years.
