Something is chewing leaves of my bean. I looked carefuly on both sides of the leaves and find nothing except for one or two aphids in a couple of leaves. Most of leaves stay clean without any trace of pests. What else could cause such a massive damage (almost on all leaves)?

I think the pests might be Japanese beatles. We have a lot in our garden - hundreds or perhaps even thousands of beatles trapped in bags I set. However I only see a few occasionally on the leaves of the beans. Maybe they feed the leaves during the night and then be trapped by my beatle traps during day?

It looks as though you've discovered the culprit Nan. I was trawling the net for moth larvae and aphids - never actually thought of beetles. Here's a web site all about your little horrors with different methods of controlling them.

Thanks Eileen for the link.
We do have the problem of Japanese beatles. They emerge from June to August in our area. Three years ago, Japanese beatles almost defoliate my two cherry trees, until I set out Japanese beatle traps. They work very well. I almost cannot see any beatles else where except for bunchs and bunchs in the bag of the trap. That is why I wonder how the beatles got on my hyacinth beans.
