Huh, I did not know that potato bugs/rolly pollies are called woodlice. I am aware that calling woodlice (heh, new word!) potato bugs is a regional thing, and that term could mean a number of different bugs. Anyways, your comment led me to look up woodlouse out of curiosity as to what blue bugs you got from Etsy, and I learned something new today! Something I probably should have learned 45 years ago, but whatever. Thanks!
