'pillar mansion

Noticed this on a neighbours tree today....



I've never seen anything like this before, it's around 2m off the ground and an apple tree I believe.

Any ideas what and why?

- sorry for the poor pic

- it was hand held at 600mm and obviously I couldn't stop the tree moving in the wind!

They could be Codling Moth caterpillars.

That's what I was thinking.
Last time I saw this I sprayed my apple tree in the front garden.
