I have never seen one. I have never lost a lot of irises. I have had some just dwindle away refusing to thrive but no instances of goop on the leaves or moths or borers that I have seen or holes in the rhizomes. Now, that being said my irises will probably get a text book case. I don't want to see a fat, gray repulsive thing anywhere! ......especially on something that I take such joy in. Talk about nightmares!
