For identification purposes make sure you get a top down shot with a sense of scale (much like your fingertip shot on the other thread) these don't have to go in the
Gallery-you can go for more aesthetically pleasing angles for there-but can be posted in the forum for people to look at. Spiders are a very difficult group with a lot of identification coming down to close examination of the sexual parts (the epigyne in the female, which is at the base of the underside of the abdomen (nearest the thorax) and the palps of the male) and I'm not sure whether many macro lenses can get useful shots of these in a natural situation.
