Holes on Hostas, not from slugs

I have holes in the leaves of my Hostas this year...I've baited for slugs, but aren't catching anything, so it must be some sort of other pest or fungus?


Doug says it could be any number of beetles, flea beetles - unless you can see them, it's hard to identify.

But a dusting with diatomaceous earth should stop them cold.
