Or possibly a chucky pig, gramersow, roly-poly, grandad or butchy boy. Although it is most probably a slater seeing that it was photographed in Scotland. Whatever name you choose to use it is undoubtedly a wood louse.
There are, and this came as a bit of a surprise to me, five thousand different species of wood louse which seems rather a lot although there are a mere forty five in Britain. I have always been rather fond of a woodlouse so much so that, as a grubby schoolboy, I kept one in a matchbox. This was probably a lot less fun for the woodlouse as it was for me because being constantly loosed and then corralled again must have been very bad for his stress levels.
Interesting things about woodlice (not a phrase I thought I would ever write)…
They are crustaceans so are cousins of prawns- you can see the similarities although I somehow doubt that the addition of a handful of woodlice to a glass of pink sauce and some chopped lettuce would not make a 1970s classic.
Those who know these things say that woodlice taste of “strong urine” (see above). I worry about people who can tell the difference between the taste of strong and weak urine.
The woodlouse has fourteen segments and live for about two years. Assuming nothing eats them or treads on them.
The woodlouse moults in two stages. Back half first and then, a few days later, the front. This means than all woodlice have a sartorially embarrassing period where they are running around with trousers that do not match their tops.
They breathe through lungs situated in their hind legs.
The female woodlouse carries her fertilised eggs around in a pouch. They hatch after a few days but then take a while to develop into independent creatures.
The woodlouse is one of those garden creatures that get a very bad press – people are constantly trying to kill them as they get blamed for all sorts of misdemeanours of which they are usually not guilty. Most of the time they do a very good job of clearing up dead stuff and feasting on decaying vegetation.
Occasionally they can snack on emerging seedlings but if you spent your life eating old wood you too would fancy the occasional change.
