One of the great benefits of living and fishing in these parts is the lack of pressure to catch something. There is a strong and highly organised competitive angling scene in Ireland but I am not competitive in life and certainly not when it comes to angling. For me the simple joys of a few hours fishing for wild trout and salmon with no great expectations of success are all I want. This in turn creates a freedom to experiment, be that with tactics or patterns. One of these experiments is my variant of the the Half Stone.
A fly with its origins in the South West of England, this is a pattern I have meant to try for years now and simply never got around to it. One winter evening I was contemplating emerger patterns and though about this fly. I am unsure if it was originally meant as a copy of a hatching fly but the palmered thorax looked good to me so I set about tying a few.
Half Stone ‘normal’ dressing:
Silk: primrose yellow
Tails: a few fibres of blue dun cock hackle
Body: in two halves, primrose yellow silk at the rear, moles fur dubbed on to the tying silk at the front
Hackle: a blue dun hackle palmered over the moles fur
While I liked the overall shape of the fly I felt the colours were too bright for the rivers here so I set about making a few alterations. I wanted to retain the half palmered look but felt adding a second hackle would give the fly more ‘life’ so I added a ginger cock hackle and wound it with the blue dun. Then I added a rib to lock the hackles in place. I also figured the primrose silk was a bit too bright for what I wanted – an imitation of a hatching ephemerid. So I swapped the primrose for gossamer no. 6, a much more muted shade of yellow.
Both hackles tied in together
Tail fibres tied in
A pinch of mole’s fur
Gold wire tied in and the thorax dubbed
hackles wound down over the thorax

I am planning on using this fly during Large Dark Olive hatches and by fishing it wet on the top dropper position I can keep it fairly close to the surface where I hope it will fool the brownies mopping up emergers. There is a very particular situation which I have in mind for the pattern. Much of the rivers where I fish are heavily wooded and some pools are only accessible from above, meaning normal dry emerger fishing (casting upstream) is out of the question. The half-palmered wet idea is my way of combatting this problem. We will see if it works soon!
