I found a web site about Althea Bushes and they had a photo exactly like the one posted on my question in Facebook. I believe the scentless bugs are a young group of just hatched? They just don’t have their color yet. Like the photo posted above. Now I need to find how to destroy the bugs before they, or I, destroy my Althea’s.

I'm quite certain these are Niesthrea louisianica nymphs. I became familiar with this species when studying how they are being used as possible control of the weed velvetleaf. Very interesting study. ~

I wonder if these are not the nymphs of a scentless plant bug in the genus Niesthrea. I'm going to put them there for now, hoping a real expert will be able to confirm or deny.
