I'm sorry, I'm too excited about the situation. Ok The leaf from the plants are like chewed, not from an animal, but like some kind of bug. Parts from the leaf are eated, lil bit from here, lil bit from there. I checked the whole leaf, from every site, I didn't find nothing on them. But it must be a bug, because an animal would eat the whole leaf or the whole plant. Its eated only the soft part from the leaf, the hard part, the veins are left. I hope you've understood what I've been trying to explain.
Edit: I don't have pics , I wasn' carrying my camera.
