It appears you have a palm leaf roller. This is a small caterpillar using the leaf as it pupates into a moth. They are also covered beside thin silk threads used to verbs the leaves closed. If you don't see any now is because they already become moths and flew from the cocoon. They only munch through during their caterpillar stage. The damage you see know is probably a moment or two old and the fern was destabilized during this cycle. Best time to get them is surrounded by late summer as they go and get ready to do this again. Check as abundant as you can of the leaves to see how many are available. If all next try spraying the leaves with a small force of marine to wash the cocoons rotten the tree. Have to spray them early, if not here to roll the leaf beside silk protects them as water or insecticide roll sour the water proof cocoon
