A hugely sucessful fly when trout are feeding on or near the surface it was originally tied to represent the large buzzer pupae on Loch Leven, however this fly catches fish everywhere, a team of three shouls be fished on a slow sinking intermediate with a slow figure of eight retreive with the occasional long pull, or as the top dropper fly with two nymphs/buzzers below, alternatively as part of a washing line, but be careful takes are savage
This is the most common colour of early-season hatches of this aquatic insect. Included in a team of three this pattern is best fished on a long leader and floating line. Change the position of the fly to fish it at various depths.
A good colour combination in this pattern really helps, especially the yellow tail which is another addition that helps create movement and interest. Put together with the body hackle this is a tempting morsel and gives good results.
