Is a ''pill bug'' just a ''sow bug''?

[Albert_136]

Is a ''pill bug'' same as ''sow bug''?
Or are they different critters?
Or do the names overlap?
Or....?

[jeff84]

yes they are both common names for the same critter. there are basically 2 different varieties. those who curl up into perfect little spheres and those who really don't although you can make them, but they wont do it on their own. neither are harmful to plants
