  • Filmed in my back garden, a population I have intentionally grown on some cherry bark under my own cherry tree. Simply teaming with life, all started by me, I feel like a creator and enabler!
    A woodlouse is an isopod crustacean with a rigid, segmented, long exoskeleton and fourteen jointed limbs.
    The exoskeleton must be progressively shed as it grows. The moult takes place in two stages; the back half is lost first, followed two or three days later by the front.
    This method of moulting is different from that of most arthropods, which shed their cuticle in a single process.
    A female woodlouse will keep fertilised eggs in a marsupium on the underside of her body until they hatch into offspring that look like small white woodlice curled up in balls.
    The mother then appears to "give birth" to her offspring. Females are also capable of reproducing asexually.
    Despite being crustaceans like lobsters or crabs, woodlice are said to have an unpleasant taste similar to "strong urine".
    Living in a terrestrial environment, woodlice breathe through trachea-like lungs in their paddle-shaped hind legs (pleopods), called pleopodal lungs.
    Woodlice need moisture because they rapidly lose water by excretion and through their cuticle, 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.
