Something is eating our eggplants!!! Can you identify it?

Something is chewing down the eggplant leaves, nibbling on them. Something else appears to be consuming entire leaves! Here are pictures of our four eggplants, three purple and one white (no plants on them yet). The white is the worst, looks like it's almost gone.

If you know what type of pest could do this, let me know! We have a fence around the garden so it's unlikely to be rabbits, although could be smaller varmints like groundhogs or woodchucks. Could it also be insects?

Thanks!

Note, fourth and fifth images are of the same plant; four plants in total. I've drawn red boxes around the damage.
