that price difference is a result of marketing plain and simple. IMO they are the same morph. and as far as selling lessers as butters goes you can pretty much bet that it's happened. I really don't know how people can say they affect combos differently when there is such a huge variation in how the base morph looks. you could breed a light butter/lesser to say a low white spider and a dark butter lesser to that same spider and get 2 completely different clutches. for that matter you could probably get 2 different clutches breeding the light lesser/butter to the spider 2 years in a row. for me I wouldn't spend a penny more because an animal is named butter. what I would pay more for is an exceptional representation of the morph.
