Meet the chucky-pig
Our rural forebears endowed the humble woodlouse with more local names than any other creature found in Britain, discovers Ian Morton
The humble woodlouse has been known by many names, reveals Ian Morton
Bibble-bug, chisel-hog, palmerworm, monkey-pea, chuggy-pig, roly-poly, Johnny-grump and slater: these are just a handful of the extraordinary number of nicknames garnered over the centuries by a diminutive crustacean that attracts scant regard or affection today. Many were spelling variations, but the sum total has been put at 176.
Some names related to special properties. lockchester, recorded in a 15th-century english-latin dictionary, Promptorium
Parvulorum, compiled in Norfolk, recognised its ability to curl into a ball. Cudworm, a Shropshire name, referred to its local function as a cattle-feed supplement. Cheesy-bob noted its collective odour. Carpenter and coffin-cutter reflected its woody habitat. Armadillo-bug drew an obvious comparison.
by far the greatest number of folk names related to pigs—94% of them, according to one assessment. in 1988, with the help of the Devon Women’s institute, researcher Dr F. J. M. laver recorded name distribution across seven county areas with sow-pigs in 81 cases, chucky-pigs in 31, grammer-pigs and granny-sows in 24, pigs in 15 and pigslice in 14. The reason, it has been suggested, is that woodlice look like feeding piglets or pigs huddled in a pen.
Presumably the same thought struck the classifiers who placed common varieties in the porcellionidae family. Porcella is latin for piglet.
For a century and more, the nomenclature has engaged a succession of good folk concerned about the depletion of our language heritage. in 1917, the St Andrews university ornithologist Dr Walter Collinge, who had compiled more than 100 local names, appealed to readers of Nature for more and he was still in pursuit in 1935 and 1946.
Devon conservationist H. g. Hurrell compiled a three-figure list and a 1965 report on Devon dialects by gillian Moore listed 34 names. in his Fauna Britannica of 2002, horticulturist Stefan buczacki noted more than 150 names. inevitably, lists overlapped, but the quest continues. As recently as 2015, the british Myriapod and isopod group (bmig) issued a lengthy resume on the whole name-gathering narrative.

‘Rural youngsters have always been fascinated by the little creatures’
British engineer Sir Harry Ricardo described how he and fellow pupils at their Rottingdean prep school whiled away boring Sunday sermons by racing woodlice on the shelf on the back of the pew in front, coaxing their runners—identified by paint specks—to greater speed by judicious tickling with feathers. Too much urging and a competitor curled into a ball and suffered disqualification. Among those to whom young Harry imparted his technique was family friend Rudyard Kipling.
Zoological archaeologist Julie Curl recommends woodlice as pets for children at home and school. Kept in an old fish tank or plastic storage container in a layer of compost or leaf litter sprayed to remain moist, they will live on kitchen peelings and can be left for long holiday periods without harm. ‘They’re interesting to study and are very good if you have an allergy to the usual fluffy pets,’ notes Miss Curl. ‘They don’t bark at the neighbours and friends, don’t scratch the furniture and don’t poo on the carpet—what more could you want?’
Of the order Isopoda and related to lobsters and crabs, woodlice have been around virtually forever. Ancestral trilobite fossils date from the Eocene period 50 million years ago, but the existence of some 3,500 species worldwide suggests that they were present before the continents drifted apart 110 million years earlier. They were here, of course.
Sifting debris from two archaeological sites in Leicester centre, including High Street cellars, entomologist Jon Daws found mineralised woodlouse fragments from the Roman period and intact examples from 1100 to 1400. Five species were present, four of them widespread and common, but one was associated with farm buildings and to find
Porcellio dilatatus in an early urban dig ‘was quite exciting’, declared Mr Daws.
Today, nearly 50 types are found in Britain, of which 37 are native or naturalised and the rest have arrived with imported houseplants. Entomologists examining the Eden Project in Cornwall reported that, in the seven years after its 2003 opening, 14 species of woodlice had established in the rainforest biome, with a further four in the Mediterranean biome and seven more in the outdoor area, with 11 species either new or poorly researched.
Three types are common, ubiquitous and number in untold millions, the familiar 14-segment woodlice with seven pairs of jointed legs found in every rotting tree stump, log pile and garden, living off and usefully recycling decaying wood. Some have two pairs of lungs, some seven and some no lungs at all. Females have two genital vents, both of which have to be serviced, and carry pouches in which the young develop before emerging as white, yellow, orange or grey miniatures.
They face a greedy world, sharing their habitat with spiders, beetles and centipedes, which eat them, and mature woodlice can turn cannibal in the mating season. They provide a main food source for shrews, but foxes and owls will also take them.
An 1885 book by Vincent Holt advising that woodland produce could alleviate food shortage among the poor included ‘an excellent sauce for fish’, with boiled woodlice added to butter, flour, water, salt and pepper (see also, COUNTRY LIFE, August 23, 2017). Hugh Fearnley Whittingstall demonstrated woodlice fritters on TV in 2012 and confirmed their shrimp flavour, but they are not on his River Cottage Canteen menu in Axminster.
Despite their lowly place in the natural pantheon, woodlice have attracted minor poets. Irish-born Francis Duggan was on their side as ‘the tiny gleaners of Mother Earth’s soul’ and ‘friends of Nature… and You too be Nature’s friend by leaving them be’. Oxford-educated Edith King saw the woodlouse as ‘a medieval knight who’s found it wiser not to keep his armour very bright’. American Aracelis Girmay wrote lines about her sister, who smuggled woodlice into bed ‘to mother them so that they would have two warm blankets’.
Their survival in the national vernacular is fading, of course. A who-and-where questionnaire by Plymouth University during its 2012 Insect Week elicited 30 responses. These included hardybacks (Northumberland), penny pigs (Essex), pellet bugs (Buckinghamshire), slaters (Dumfries), tanks (Warwickshire) and cheesy-bugs (Berkshire and Kent). ‘At least some of the old names are remembered,’ remarked Anthony Barber of the BMIG. ‘One wonders how many generations must pass until these are only found in books on folklore and everyone refers to them only as woodlice.’
Less regrettable, perhaps, is the contribution of the little creatures to cottage tradition. Live woodlice in a bag tied round the neck were said to alleviate infant teething pains and would also cure smallpox, the disease retreating as the lice died. Swallowed live, they would cure both whooping cough and constipation.
For the gentry with costive bowels, they were dried, pulverised and mixed with Rhenish wine, curing, at the same time, jaundice, ague and failing eyesight. For a rickets sufferer in Gloucestershire, 300 live woodlice stirred into 12 pints of mild ale together with raisins, rhubarb and fern roots would affect a cure, but the remedy should be drunk in spring or autumn.
