We have those and the regular "ball bugs" here in Mo. Those Sow Bugs aren't as fun to play with, because you can't roll them like ball bugs. I used to walk around with jars containing a
lot of them when I was a kid.
One time I was running in to go to the bathroom and tripped, which caused my jar to fall and break. I was crying, and my parents came running to see if I was hurt. (They heard the glass break). When asked if I was hurt, I said "No, but my ball bugs are getting away!" They were going across the room, and up two walls.
After that, I was
encouraged to leave my bugs outside.
(It only got worse though, because in my teens my pet snakes would get out, and sometimes the mice I was raising as snake food would escape too. I only had one snake that was never recovered though. It was a 3 to 3.5 foot Prairie King Snake).
