Am I being Attacked by a Bug? I Cant See it!

i noticed this damage on my leaves it doesnt look normal, but i dont see any bugs other than those damn little tinny black/brownish flies. any ideas what this could be???

thanks
Cat

hmm that looks weird idk what else that would be if not a lil bug nibbling on it

yea thats the only thing i could think of that would do that =/ what kinds of bugs could cause this kind of damage???

it looks like a big bug is around, could be a worm or something, take your time and just look around your plant and under the leaves, it must be somewhere. Or if it was just two leaves and no more are being "eaten" it may be gone already.
