Not sure if I spelled it right,lol. Anyway,years ago we would get the Catapla worm off the tree and use for fish bait, it was the best. Now here in central part of Louisiana we have Catapla trees and no worms. Would like to know why the worms(or caterpillar) are gone. What can be done to get them to come back. Friend says he ordered the Catapla worm and put in tree and they disappeard.
