Continuing on with the mayfly theme, we come to the next pattern in the cycle.
The sparkle dun is not quite an emerger nor an adult imitation but a cross between the two.
It captures some of the attributes of the emergent dun and some of the adult insect. In essence it is the adult in the most perilous stage of its journey having emerged from its nymphal shuck and unfurling its wings in preparation for flight.
This pattern retains a sparkle in the tail that is the trigger point as it imitates the last remnants of the gas bubbles used to break open the shuck. It is these gasses that reflect the light that signals to the trout ‘nymph here’. The rest of the materials are of a dull nature, which truly represent the dowdy colours of the adult.
This pattern is a low rider in that it sits well down in the surface film and therefore is really suited to fishing in impoundments or the flat water or slower sections of lowland streams.
An ideal time to fish this fly is from mid-hatch onwards; a time when there is a whole range for the trout to choose from, such as a few remnant nymphs, emergers, escapees, and then the adult mayfly.
Rises to this pattern are a slow casual affair as the trout seem to sense that at this particular stage of the hatch these ‘escapees’ are not going anywhere in a hurry and can be picked off at leisure.
If one is caught up in the frenzy of a full-scale dun hatch it can seem as if the whole lake surface is boiling as trout bulge, slash, boil, and sip their way to oblivion. The angler again in this situation should concentrate on one working fish or a patch of water rather than trying to cast to the whole lot, which will surely result in a migraine if not a broken rod.
On those breezy days fishing with the wind is the go, have the wind at your back and cast short lines to allow the breeze to make the fly to appear to drift naturally, as soon as it begins to drag lift off and cast again. Another successful method especially on the weed lake margins is to fish the fly into the clear patches in the weed beds; trout will sometimes sit in these clear patches and pick off duns at will.
In smaller sizes this fly is a deadly fly for flat sections and the broad slow reaches on streams and rivers, the deer hair wings sits up enticingly and are easily seen by the angler. If one chooses to add a dropper off the bend of the hook, the upright wing makes for a good strike indicator.
