On my walk around town today I found this small black bug, (keychain carabiner for scale).
It has two antenna and it seems that there is white on the edge of the segments.
Does anyone know what kind of bug this is?
Probably a woodlouse which is a type of crustacean in the suborder Oniscidea.

They are globally distributed, except in polar regions and arid deserts, and are also known by the following names:
- "armadillo bug"
- "boat-builder" (Newfoundland, Canada)
- "butcher boy" or "butchy boy" (Australia,mostly around Melbourne)
- "carpenter" or "cafner" (Newfoundland and Labrador, Canada)
- "cheeselog" (Reading, England)
- "cheesy bobs" (Guildford, England)
- "cheesy bug" (North West Kent, England)
- "chiggy pig" (Devon, England)
- "chucky pig" (Devon, Gloucestershire, Herefordshire, England)
- "doodlebug" (also used for the larva of an antlion)
- "gramersow" (Cornwall, England)
- "granny grey" (South Wales)
- "monkey-peas" (Kent, England)
- "monk's louse" (transl. "munkelus", Norway)
- "pea bug" or "peasie-bug" (Kent, England)
- "pill bug" (usually applied only to the genus Armadillidium)

I see these everywhere where I live (Central Texas). We usually call them "pill bugs" or "rollie-polies" (usu. young children).
It shouldn't do you or anything you own any harm; they mostly just crawl around on things and roll up into a ball when you touch them. Kids would always run around collecting them when I was in school.
