My bean foliage was starting to look like lace and I thought that the Japanese beetles were doing the damage. Since JB season is pretty much over, I figured it had to be something else. I found these ugly yellow bugs hanging out under the leaves of the most severely damaged plants. Strong bursts of water and even insecticidal soap have done no good. Please help ID this ugly thing! Any tips on how to get rid of it would be appreciated too... =)
