Answer by  shastie (1601)

It is most likey a bagworm. You will notice a nest that looks like a big bag. They use the needles to make the nest for the larve and then eat at your tree. Your best bet is to get rid of the tree or get a pro in as soon as possible.

It is more than likely a Bag Worm and they can be very destructive. A permethrin-based insecticide will kill them. The earlier in the season that they are taken care of, the more effective it will be.
