This fly was created by Canon Greenwell in 1860. It is still as popular today as it ever was. This fly has stood the test of time for a very good reason; it works and it works well! This is a fly no river trout angler should be without.
This is my own creation to imitate the Iron Blue Dun. I’ve experimented a lot with different colours, different materials etc and this is the combination that I found works the best for imitating the I.B.D.
Originally created as a lake fly in 1860 as a midge imitation. It is also just as effective on the rivers. A must have pattern for any wet fly angler on the rivers or lakes.
