What is this?

Never before saw this.. it seems something attacked the tree I planted on the street.

Anybody knows what that might be, and what can I do about it?
The third image shows familiar animal, but still... the intensity of attack is really curious.

Look like moth eggs almost to me

Yep moth eggs.

I normally try the hose first!
If they don't budge, pyrethrum or pest oil should do the trick.

Thank you guys!
So, my tree is not in real danger :-)
