Can you dust them with Rotenone or something organic? I don't know what kind of bug that would be. Sorry.

I was thinking I'd dust them with DE just to see what happens. The not knowing is killing me!

The only thing that attacks my pole beans are leaf rollers, larvae of the Long-tailed Skipper butterfly. Hand picking is the only control I use for them. The eggs are bright yellow and the caterpillars have enlarged, reddish heads. The adults are quite aggressive if they're trying to lay eggs and I'm in the way! They'll fly at me almost like they're angry at me for hanging around their nursery!

The munching might be early in the a.m. Tiny holes make me think of flea beetles, but I've never had them here. Have you encountered those in the past? They are very tiny & jump away when disturbed. I have had fleahoppers, but they are sucking insects, not chewing.

There are various small caterpillars (often feeding @ night) of tiny moths that can be almost impossible to catch in the act. Have you tried Bt yet?

Thanks for the suggestions everyone! Carol, I have encountered flea beetles before (only in TN - they are a PAIN!) but I'm not seeing any here. I guess I'll try some topical stuff & keep checking - hopefully the plants will grow out of it the way the lettuce seemed to.
