Lets talk lesser and butters

[MarkS]

Well, how about the difference they create when combined with other morphs?

For example, the butter spider and the lesser spider.

I think the examples you are using are an older animal and a younger animal which to me explains much of the darkness. Not that it's that much of a difference mind you.

Personally I think they're the same morph, just different founder animals from different wild populations. I predict that the more they're outbred the quicker you won't be able to tell them apart.

You can't tell them apart now in a lot of collections.
