Will some types of egg laying enemies be able to lay more eggs based upon what subspecies of oviparity animal it is. An example is an butterfly can lays an average of 300-400 eggs in the wild but the only problem is that the eggs will have to be smaller than fly eggs and almost all of the eggs will not survive but your character can extract the eggs via pleasing herself. I would go on more but I won't.
Good idea or noteworthy idea
