Sort of need to know what sort of bug it is. If you can't see the bug can you describe the type of eating that they are doing? Are they eating little holes in the leaves or are they munching from the outside in?

Egg plants and capsicum are generally quite bug resistant - I wonder if it isn't a slightly larger bug like a possum...
Hi Muppity,

Looks like a bug, it is small holes in the leaves - all over!!!! inside and outside, but I can't see any bugs - just where they have been!
