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. The woodlouse has a shell -like exoskeleton , which it must progressively shed as it grows.
The moult takes place in two stages; the back half is lost first, followed two or three days later by the front. This method of moulting is different from that of most arthropods, which shed their cuticle in a single process.
A female woodlouse will keep fertilised eggs in a marsupium on the underside of her body until they hatch into offspring that look like small white woodlice curled up in balls. The mother then appears to "give birth" to her offspring. Females are also capable of reproducing asexually. Despite being crustaceans like lobsters or crabs , woodlice are said to have an unpleasant taste similar to "strong urine".
Pillbugs woodlice of the family Armadillidiidae , also known as pill woodlice can be confused with pill millipedes of the order Glomerida. They live in very similar habitats, and they can both roll up into a ball. Pill millipedes and pillbugs appear superficially similar to the naked eye. This is an example of convergent evolution. Pill millipedes can be distinguished from woodlice on the basis of having two pairs of legs per body segment instead of one pair like all isopods.
Pill millipedes have 12 to 13 body segments and about 18 pairs of legs, whereas woodlice have 11 segments and only seven pairs of legs.
Many members of Oniscidea live in terrestrial, non-aquatic environments, breathing through trachea -like lungs in their paddle-shaped hind legs pleopods , called pleopodal lungs. Woodlice need moisture because they rapidly lose water by excretion and through their cuticle , and so are usually found in damp, dark places, such as under rocks and logs, although one species, the desert dwelling Hemilepistus reaumuri , inhabits "the driest habitat conquered by any species of crustacean".
A few woodlice have returned to water. Evolutionary ancient species are amphibious, such as the marine-intertidal sea slater Ligia oceanica , which belongs to family Ligiidae. The woodlouse eggs hatch after an incubation period of just a few days exposing the woodlouse babies. Due to the fact that the baby woodlice take a number of months to fully develop, the mother woodlouse will often stay close to her young until they are adult woodlice.

The feelings of recent seasons wash through me, a sharp intake of breathe brings the near past back.
Glass rushes and smashes into the back of a recycling truck by the restaurant next door, as the engine idles and memories sidle and pounce. Waves of how it felt to be me the last time I heard this sound in this way, the last the time the passing of traffic and the singing of birds drifted languidly up and hung in the air, the last time the air touched my skin in this way, the last time the duvet enclosed me in quite this way: in the warm, still, morning air bringing melancholy and mourning, that nameless yearning, triggered by intrusions of the past but still looking to the future.
The unknown future, full of options and choices, uncertainties and journeys and…. A myriad of possibilities — if only I could leave the comforting embrace of this soft duvet as the world outside wakes up and rises. I was a bit of a rush job. The song began life as a song I made up to entertain myself on a rare straight and less-interesting bit of road, while on a cycling adventure in New Zealand. There were some incredibly bumpy, corrugated gravel roads, rocky and bumpy tracks, and the bike had a very hard saddle.
Then the song got longer on a later cycling trip around Cornwall, with similar issues. I was challenged on Facebook to a 7 day monochrome photo challenge, and found I was enjoying the discipline of doing a specific creative thing every day, with simple defined boundaries — so I kept going for days! I have plans now for continued challenges to keep me motivated.
First up is 50 days of Tenacious Triffids I may extend it, but would prefer to find another simple theme for the next 50 days. That will be on alternate days, with the in between days being a drawing or painting inspired by or based on photos from the monochrome challenge and following challenges. There was an earthquake a couple of days ago, near Swansea. It was incredibly mild, but the sofa suddenly wobbled beneath me in a very particular way that immediately felt different to the usual vibrations of passing traffic, or storms shaking my in-the-roof flat.
I like it on the acoustic mandolin too, but here it is with the electric, just to maximise the pointless melodrama.
