I have been attempting to learn about as well as tie Spiders. In referencing, it appears that the English as well as the Scott's lay claim to the spider.

The problem I am having is trying to distinguish the difference in characteristics of the two. From what I am able to understand, they are as different as night and day.

Any help would be greatly appreciated.

Here is an excellent link, but it's just not quite enough information
