Larvae (bagworms) construct spindle-shaped bags covered with pieces of twigs, leaves, etc., and remain in them -- enlarging the bags as they grow -- until they pupate (also in the bag). Adult females remain in the bag, emitting pheromones which attract adult males to mate with them.
I'll bet if you carefully pulled it apart a bit you'll find a small caterpillar in there. No idea which kind though. You can sea where the caterpillar ate the leaf. This may be a disguise for the cocoon or chrysalis? I think I can see a little bit of white cottony silk in the center.....
