May came and went with unreasonable haste. I hardly wet a line during the merry month, a combination of work commitments and Mediterranean weather kept me occupied and the fish unmolested. Reports suggest the mayfly was late but is still hatching in good numbers as I write in the first week of June and as usual some trophy-sized trout are being landed on the big loughs.
So in keeping with the time of year here is a pattern for a dry/hatching mayfly imitation which I dreamt up a few seasons ago. It works well when the fish are mopping mays off the top and Lough Conn trout in particular seen to like this one. Tied on a size 10 hook, different colours can be used such as yellow, olive and green to meet the requirements on any given day. I will show you the yellow version here today.
Tying silk can be either olive or fl. yellow. If you use the yellow it creates a very bright fly so it pays to have some of both in the box.
Run the silk down the hook to the bend where you tie in 3 or 4 fibres from a moose mane. I much prefer this material for making tails to the more traditional pheasant tail fibres because they last so much longer. Even up the ends of the moose hair before tying them in and aim to flair them out (a small ball of the body fur under the tail can help here). Now fix in a piece of rib which is globrite no. 4 floss. Dub a body of seals fur in the colour you desire. Leave plenty of space at the neck of the hook for tying in the wings and hackle. Wrap the floss forward in even spirals and tie it in at the head.
Now for the wings which are made of 4 CDC feathers. These are tied in over the back of the hook, almost in wet fly style. Tie in a matched pair of grey CDC with yellow or green CDC flanking them. I especially like the ‘dirty yellow’ CDC from Veniards. Take time to get these wings sitting just right, nice and straight.
The hackle is made from a good quality grizzle cock hackle dyed green or yellow. Tie it in and make at least 5 turns before tying it off and snipping off the waste. Form a head and whip finish. I make the hackle quite thick because this is a pattern which will be fished in a wave so it needs to be fairly robust.
The fly can be fished either well greased and riding high on the waves or ‘damp’ with just the CDC keeping the fly in the surface imitating a hatching insect. I use it on the loughs but there is no reason why it wouldn’t work on the rivers during a hatch. I like to fish this one on a cast with a spent gnat imitation in the evening. Sometimes the trout will prefer one fly over the other but often both will take fish in equal proportions.
