Partridge and Orange:This spider pattern is good one in coloured water.
A good tip is if you tie them, prepare the hook beforehand with Tippex, so the orange floss is still bright when wet. Good as a dropper fly with a gold head nymph, Grayling love this one.
A variant can be tied with yellow or with rib & tail.
Partridge and Silver:I can't remember where I came across this one, but I believe it's an established pattern.
To Tie, dress sparse, thin silver tinsel body you can strengthen with a wire rib or even with lead wire to make it a quick sinker,
Biblo: This really is the king of all spider flies, it must be the red stripe. Usually made in 12-14's they can be tied sparse or bushy, a good hot day fly when nothing happening. Good in ones and two's, I tie a one with green or red holographic stripe.
Greenwells Spider: Another all rounder. The smaller the better.
Yes and there's dozens more these include patterns made with waterhen,starling ect. Surf the web and look yourself. I recently saw some excellent sites made by Yorkshire Anglers, they know there spiders!
