What are they called?

When I was younger, I liked playing with the black worms that quirled up in a ball. The nick name I call them is 'rollie pollies'. What are they?
Answers:
Pill Bugs are these "Rollie Pollies"
They're fun.
Pill bugs belong to the family Armadillidiidae. The scientific name is Armadillidium vulgare.

Pill bugs, also called a "potato bug" or "doodle bug", is actually called a wood louse. Although commonly thought of as insects, they are actually crustaceans, the same as a lobster, crab, or crayfish. The body of the pill bug is composed of several segments. Using special muscles the pill bug can roll itself into a ball, leaving only it's tough outer shell exposed. This distinguishes from the sow bug, which appears similar to the pill bug but cannot roll itself into a ball.

Pill bug can typically be found in dark, damp places such as the underside of rocks, fallen trees, and deep grasses. They typically hide during the day, coming out only at night to feed. Some desert-dwelling pill bugs will even burrow deep into the sand to avoid the daytime heat.
Hope that helped...

Pill bugs.
"rollie pollies" are also known as "potato bugs". they're harmless to humans
Armadillidium vulgare
(pill bugs, sow bugs, rolly pollies)
Armadillidium is a genus of the small terrestrial crustacean known as the woodlouse. Armadillidium are also commonly known as "pill woodlice", "pill bugs" or "roly-polies", and are often confused with pill millipedes such as Glomeris marginata. They are characterised by their ability to roll into a ball when disturbed. They typically feed on moss, algae, bark and other decaying organic matter. They are usually found in moist areas such as decomposing leaf matter and soil.
The colouration especially of young A. klugii resembles the red hourglass marking of the Mediterranean black widow Latrodectus tredecimguttatus. This is probably a kind of mimicry, to ward off predators that mistake the harmless animal for a venomous spider.
Unlike other arthropods such as insects and spiders, pill bugs do not have a waxy cuticle that would reduce evaporation from their bodies. Pill bugs also use modified gills, called pseudotrachea, for respiration, and the gills must remain moist to function. Individual pill bugs typically live for two or three years, and females brood eggs once or twice each summer. Several hundred eggs are brooded at a time in the marsupium, a pocket on the ventral side of the female pill bug. The marsupium must also be kept filled with water until the young hatch and crawl away.
