I still think it's probabay slugs.

Mine looked the same, I asked my neighbor, way more experienced, she described them as "lacy", yep, slugs.

Ish.

Post a picture over on the hosta forum. Lots of experienced hostaholics there to help with a diagnosis. My neighbor's hostas were devastated by Japanese beetles, for the first time this year.

Go out at night with a flashlight....you might be surprised what you can find on your hostas that way.

Thanks Everyone,
Will post a picture as soon as I get my camera working and will do the flashlight thing this evening.
