And despite its darkish appearance the diawl Bach was just as devastating when trout singled out lake, or pond olives. As well as being suggestive of other bugs the pattern quickly gained a reputation as a generic nymph that could be used with confidence at anytime of the season.
Of course they all work and have a place in our fly box. Granted, if most anglers were restricted to a single fly it’s likely many would choose a pheasant tail nymph, but I’ll wager the diawl bach would come a close second, So if you haven’t got a few in the box then now’s the time to stock up, or if you prefer, tie your own
This is best cast out in a cross-wind using a floating line.
For those familiar with a figure-of-eight, use this to slowly retrieve the fly on a bowing line.
If the figure-of-eight causes problems for you then simply trundle the fly back using inch long tweaks. If you’re confident using two flies then position them some 4ft apart on a leader of 14ft overall. Again these are best presented a cross a breeze.
