Can anyone tell me what the white stuff is on this young apple tree?

Wooly aphids?
 
Powdery Mildew?
 
Wooly Aphids, from pictures on the internet. But when I've seen it first hand it was on dying limbs so it could be fungus.
 
Their aphids. Look close their moving and it isn’t from the wind.
 
Thanks guys. First wooly ones I've ever seen. I normally see the regular green aphids, on new growth. Those don't last very long before the predators end them. I'll check these again in a couple of days.
