Creepy crawlers on my Azalea. Help w/ID?

[Underdog]

This tree has been lagging this year. I just discover dozens of these creepy bastards hiding under every branch.

They look cute, but I don't recognize them. In Europe and lacking native azaleas, we are relatively pest-free. Are these your pest, or are they eating your pest? Or neither?

The almost look like some kind of aphid but not quite. I can't see the two projections on near the end of the abdomen typical of aphids

Bark Katydid? The antennae reminded me of the green ones I see around here. No idea, just a guess.
Cymatomera denticollis

This was also the one I posted in the other thread about wilting and non opening flowers. Maybe the cause? Their about 1/8in and fast movers too.
