How do you take care of a leaf bug?

well it depends on the leaf bug, if it is green and looks more like a leaf i don't know but if its a brownie colour, then you have to give it blackberry leaves (but don't worry it wont hurt them) or wrap the plastic wrap around a water bowl and poke a hole in it and put a branch with some leaves in the hole, this is so it doesn't drown and also remember to give it lots of love as this will make it use to you
