Roly-poly

Friends and I played with these bugs when I was a kid. We'd collect dozens of them and build little homes and such for them. We called them Roly-polies because they would roll up into a ball when scared. Needless to say, that wasn't their real name. They're pill bugs. I just found that out today after finding them on BugGuide.net. The website looks helpful for naturalists trying to identify a mysterious bug. BTW, I still think they should be called Roly-polies.

Thanks to Coffee and a Muffin for the link.
