Large Dark Olive (Baetis rhodani) Subimago/Dun Paradun

It is the end of February, and the start of the new trout season in Wales is just six days away. Focus from most of the fishing community is currently on the upcoming voluminous hatches of the March Brown (Rhithrogena germanica) and Grannom (Brachycentrus subnubilis), however, there is one invertebrate that has been active for quite a while, and one which (especially at this time of year) will be at the top of any dry fly angler’s list.

The Large Dark Olive (Baetis rhodani) hatches begin during the colder months of the year and, for me, is an invertebrate I watch out for very closely at this time of the year. Other than midge (which are in our waterways twelve months of the year), LDOs can be seen trickling off during warmer periods of winter days. At the start of the season, this is one of the main invertebrates I look to imitate.

Over the past few seasons, I’ve found myself fishing and tying with more regularity messier/noisier emerger patterns of CdC, Hare’s Mask, and Snowshoe Rabbit fur. They are just too good at imitating that critical stage of the life cycle where the invertebrate is held helpless in the surface film. As it attempts to scramble free, full of emerging legs and exploded carapace, to the trout, it looks like nothing other than a good, meaty morsel and protein-packed snack to be easily taken.

However, I’m a hackle tart at heart, and I love tying with rooster feathers. For the faster, more broken waters I fish at home, the paradun, both highly buoyant and visible, is a firm favourite, and at this time of year, when waters might be running a little higher than in summer, what is there that’s better?

    Stealing that Gareth, loving the contrast between the ribbing and abdomen.
