Little bugs doing damage to the underside of my soybean leaves

I swear the bugs know it’s May and just love to come out this month. I’m not sure if these are thrips. Can anyone tell by this photo? There’s damage on the undersides of my soybean leaves. How much of a problem is this? I’m trying to go as organic as possible. If I do need to get rid of them, what techniques have you had the most success with here in Florida?
