I've got some kind of critter eating the underside of the leaves of my tomato plants. Does anybody recognize this? Any ideas about how to fight it organically? (I garden in containers on a second floor porch.) I guess I should add that so far I haven't seen any critters when I look at the undersides of the leaf
THis is the underside of the leaf. Hope the pic give you a good enough idea of what they are doing.
And the top. Where everything is eaten away, the leaf is like paper.
