The woodlouse includes a shell-like exoskeleton, which it should progressively shed since it grows. The moult requires location in two stages; the back again half is lost very first, adopted two or 3 days later through the front. This technique of moulting is various from that of most arthropods, which shed their cuticle in the single procedure.

A female woodlouse will maintain fertilised eggs in the marsupium about the underside of her physique right up until they hatch into little, white offspring. The mom then seems to “give birth” to her offspring.

Some species of woodlouse are capable to roll right into a ball-like kind when threatened by predators, leaving only their armoured back again exposed. This capability, or dominant behavior, explains numerous from the woodlouse’s frequent names.

Metabolic charge is heat dependent in woodlice. In contrast to mammals and birds, invertebrates aren't “self heating”: the external environmental heat relates directly to their charge of respiration. they aren't usually regarded being a severe household pest as they don't distribute illness and don't harm wood or structures; nevertheless, their presence can indicate dampness difficulties.

Woodlice are eaten by a broad variety of insectivores, however the only creatures identified to prey exclusively on woodlice are spiders from the genus Dysdera, this kind of since the woodlouse spider Dysdera crocata.
