Thanks, Ron, I believe you've hit on what it is. Do you happen to know whether or not this beetle is a threat to green bean plants? Quoting from the info on the Guide pages about this beetle, "This species is associated with Commelinaceae, having been recorded from Commelina spp. and Tradescantia sp." I speak primarily English, and I have no clue as to what that means. It would be nice if people would do like you did - and include the English name along with the Scientific name. That was much appreciated!
I see where Illinois isn't represented for July, so I suppose I'll move my images over to the Guide. I'm convinced it's what you say it is. Thanks for identifying it for me!

beans are in the family Fabaceae and these beetles are probably not a threath to your beans. Commelinaceae are a family of mostly small herbs often found together in herby patches along with beans only usually in the more shaded/moist places.
I agree with Neolema sexpunctata by the way

Well, that makes sense, because there are herbs planted close to the beans. Sweet Basil and Oregano. That's probably what attracted the little fellow. Thanks!
