2. (zoology) A carpenter bee.Examples: "The large, stout African bees are carpenters (Xylocopa), making small tunnels in timber, housing few individuals."

3. (Canada, British, regional) A woodlouse.Examples: "Eleven names in Laver’s table (just over 6%) are of the “carpenter” type, a name for woodlice also recorded in Shropshire and Warwickshire.[…] Apparently a Newfoundland word for woodlouse is “carpenter” or “cafner” (another is also “boat-builder”). These names clearly relate to the animals’ affinity to wood as will “carpenter’s flea”, “wood-pig”, “wood-bug”, “grampus wood-bug” and, of course “woodlouse”."BritishCanadaregional
