Here is a dabbler pattern I created some years ago to use during the mayfly hatch on Lough Carra. It’s proved to be a consistent killer and has taken trout from the other lakes too, so I can vouch for its effectiveness.
I used to keep a boat at Moorehall on Lough Carra and enjoyed some great fishing on that lovely water but these days the fishing on Carra has deteriorated to the point where I no longer leave a boat there. It’s easy for me to get a loan of a boat on any of the local lakes so I fish Carra occasionally these days when I hear the trout are rising.
Carra has long been famous as a lake with a massive hatch of mayfly. Sadly, there are fewer and fewer mayfly each season now but the fish still respond to a well fished artificial. I prefer Carra on a day of big winds when large waves roll the length of the lake. Big winds seem to stir the bigger trout in my experience. This pattern was designed to be fished in just such conditions.
Tying silk: brown
Hook: heavy wet fly, size 8
Tails: Cock Pheasant tail fibres, about half-a-dozen
Rib: thick brown silk. I use rod whipping silk which has a nice colour and is very strong.
Body: natural seals fur
Body Hackle: a dark red game cock hackle, palmered
Shoulder hackle: a grey partridge dyed golden olive or yellow
Cloak: well marked bronze mallard tied all round
As you can see, this is a simple dabbler style pattern and it is easy to tie. To my eye the natural seals fur is an excellent match to the ivory coloured body of the naturals. The trout certainly approve and it has been a very consistent pattern over the 20 odd years I and my friends have been using it.
I recommend that you fish this fly as part of a three fly team. It has caught me trout in all positions on the leader but if pressed I would put it on the tail in preference to the droppers. Many times I have boated trout on a wide range of patterns on the same drift, so exact copies are not usually required in a big wave. The secret is to find the fish where they are feeding and this is not always easy. Experience plays a large part in finding the trout but you cover a lot of water in a big wind so keep flogging away safe in the knowledge you are going to cover fish somewhere on your drifts.
The only drawback with this pattern is the weakness of the pheasant tail fibres. These break off easily and the resulting tail-less fly is not effective. Try replacing the pheasant tail fibres with some moose main hair – it is much tougher and longer lasting.
