These are called bagworms. They are a type of moth and these are the protective cases they build to survive the winter. Their eggs are enclosed in the cases. The best thing you can do at this time of year is cut the cases out of the tree and discard them in the trash. In June next year, begin looking for new bags. Usually, they are located on the outer branches in full sun. If there is a heavy infestation, you can spray with a biological product, Bacillus thuringiensis, when small caterpillars are present.
