    You have just missed seeing the little buggers who are eating your beans...Back when I had my garden I had the same thing happen...for me it was harder to fix as there were in a plastic covered greenhouse so the natural bird predators could not gain access. I you do some more poking around you should find the larvae hiding on the underside of the leaves.

    OK thanks KMS Woodworks, I'll take a look today! A friend of mine last night said she thought it was janpeness beetles, but haven't seen any yet this yr!

    Ann, since many garden pests are nocturnal, put out a sticky trap at night and see what you catch. You can then take appropriate measures.

    also check for earwigs that are nocturnal.

    possibly Japanese beetles? They can make leaves turn into lace! I have them on my grape leaves. You don't always see them...you have to kind of look around, & you may see one or two.

    round holes like that can definitely be caused by cutworms.

    Japanese beetles like grapes, roses and rose of sharon. (I have them on my fox grapes (a weed that I need to deal with) but as long as they are eating them, maybe my roses will last longer) By the look of the holes on your bean leaves, I'd say you have have Mexican bean beetles, especially if you have any farms around that grow soy beans. I do and the beetles like 'good' beans better than soy! Years ago, with a baby a dog and many cats, I didn't want to use chemicals, so I went out 3-4 times a day with a large lidded jar, and just knocked the nasties into it and left it in the sun to sweat them to death (Sorry Hindus!) They are about the same size and shape as a lady bug, with spots too, but they are yellow, not red.

    Look like Japanese beetles to me. Pick them off each morning and put them in a jar of water.

    looks like ear wig damage, put out some tuna water in a can buried a rim level they will go in and cannot get out, they love tuna juice

    So....what are they? Too early for Japanese beetles. Did you take Douglas' advice and trap any nocturnal creatures?

    Small black beetles, pidgeons or maybe slugs. Keep them covered for a while and see if it still happens. If it does it has to be something in the ground!

    I had this happen, it wasn’t a pest, my soil was lacking iron. Sprinkled iron on the ground and it took care of the problem.
