Cold, damp spring days aren’t favoured by many but for the fisherman, they can offer superb fishing. Inverterbrates seem to favour these dour days and hatch en masse. None more so than the dimunitive Iron Blue Dun which can often save the day when you might have second thoughts about going fishing. Today was one of those days and my good friend, Nicholas Steedman, and I experienced a hatch of Iron Blue Duns of biblical proportions. The river was covered with duns! These rare occasions can prove frustrating – with more food available than even the greediest trout can feed on, they become selective and tricky to fool. Surprisingly today the stand out fly was a Large Brook Dun ’emerger’ which is generic enough to pass as a general olive emerger pattern. Large Brook Duns are frequently claimed to be of no interest to the fisherman but these large upwings often get blown onto the water or hatch mid-river (despite only being meant to hatch by crawling up stones on the side of the river). With thousands of Iron Blue Duns and a smattering of Large Brook Duns plus a few other species the trout were spoilt for choice today but the larger imitation certainly proved the most effective at fooling some tricky trout:-)

I’ve included a few photos of the fly below (previously posted on an earlier post). The body is natural stripped peacock quill which is protected by Harvey Angling’s Liquid Glass UV Cure Resin which dries clear and tack free – exactly what you want from a UV resin! Give the fly a try, you won’t be disappointed;-)
