I have hundreds of these very tiny white bugs on 6 tomato plants. They are almost see-through with sticky black feet. They look like they could be Aphid nymph castings but I'm not sure. They are motionless, completely formed with head, a slender body, legs, etc., but no wings. They can be seen very clearly with a 10 power loupe. I can brush them off, but they do stick. They are not on any of my other vegetables (lettuce). I have done several searches on the internet to find photos of them but don't find any.
Can you help identify them? Attached is a micro-photo I've taken of one of them. This bug is about .010 - .015" in length.
I don't think they're Aphids or Whiteflies.
