A possible addition to your woodlouse knowledge store might be the fact that in Scotland they're commonly known as 'slaters', Mort....
How about this (with thanks to Prof Wiki)?
Common names for woodlice vary throughout the English-speaking world. A number of common names make reference to the fact that some species of woodlice can roll up into a ball. Other names compare the woodlouse to a pig.
Names include: "armadillo bug", "cheeselog", "doodlebug", "pill bug" (usually applied only to the genus
Armadillidium), "roly-poly","parson's pig" (Isle of Man), "potato bug", "roll up bug", "slater", "Carpenter", "Wood Bug","sow bug" and, commonly used by the Duffs in Plymouth (South Devon), "Menaces". [4][5]. "Slaters" in Scotland and Northern Ireland. In north Devon and north Somerset, England, a woodlouse is traditionally referred by the quaint name "Chuggy-peg", "Chuggy-pig" or "Chuggypig". In North Somerset it is also sometimes referred to as a "Granfer Gravy". In Australia, a woodlouse is referred to as a "butchie boy", or "butcher boy", or "slater", or "slater bug". In New Zealand the word "slater" is used as well.
I wonder how many of those terms are still in daily use? I first heard "slater" in Northern Ireland in fact.
