I posted abpout this damage before. It's a white grub. If you look down the side of the cigar leaf you can pull apart the next leaf petiole next to the cigar leaf and see him. The black stuff is bug poop from digesting your cigar leaf. He's under the poop. I spray some garden insecticide in this space and the grub or grubs are killed. This happens in the spring every year to my Ae Ae pups and even when they are 6 to 7 ft tall. Repeat spraying every week until the gigar grows out. I get a ladder and keep checking for a few months.
