Definition

  • When disturbed, a woodlouse often rolls into a tight ball for protection.
  • The damp corner of the cellar is a perfect habitat for a woodlouse.

Advanced Usage

• Scientific Context: In biology, "woodlouse" refers specifically to members of the suborder Oniscidea within the isopods. They are notable for being one of the few groups of crustaceans fully adapted to life on land, though they require humid conditions to breathe.
  • The study focused on the respiratory adaptations of the common woodlouse.

Variants and Related Words

• Plural: The standard plural is woodlice.
• Regional Names: In some regions, especially North America, a woodlouse is often called a pill bug (if it can roll into a ball) or a sow bug (if it cannot).
• Related Term: Isopod (n): The broader biological order to which woodlice belong, including aquatic species.

Synonyms

• Pill bug (especially for species in the family Armadillidiidae that conglobate).
• Sow bug (often for species in the family Oniscidae or Porcellionidae).
• Roly-poly (a common informal name, especially for children).
• Slater (common in Australia and New Zealand).

Notes on Meaning

• The term "woodlouse" specifically denotes the terrestrial isopod. It should not be confused with insects like beetles or centipedes that might share similar habitats. Its defining characteristics are its crustacean nature, seven pairs of legs, and segmented, armored exoskeleton.
