Grannom

The Grannom (Brachycentrus subnubilis) is the first sedge fly of real importance to appear in the spring.  It tends to appear in April and the hatch last 10 days or so.  It prefers medium paced chalk streams and rain fed rivers and one bonus is that there are not other sedges around at this time so general any small sedge pattern will do.  On chalk streams the larvae congregate around reed beds whereas on stony rivers the glides are better places to fish in a hatch.

 

Halford’s Grannom

Halford’s dry fly version of the Grannom.

Halford notes that, ‘An even better body for this fly is obtained by selecting a strand of condor pinion-feather, which is nearly white at the point and shading into a dark slate-colour at the root; the longer flue is then stripped off the dark portion of this strand only, and the whole dyed in No. V [grannom green].

The light un-stripped part, which shows distinctly the green colour of the dye, is worked at the tail-end to form the eggs, and the darker portion the body of the fly.

The wings of the Grannom when first hatched are quite pale, but darken considerably from exposure to the air.

The trout, however, invariably prefer the newly-hatched flies, so that it is most necessary to dress them with the palest wings possible.’

Hook:  

12-14 Up-eyed Dry Fly Hook (e.g. Drennan Dry Fly)

Thread:  

Olive

Tag:  

Grey ostrich herl dyed in No. V [Grannom Green].

Body:  

Dark heron herl un-dyed.

Wings:  

Palest hen partridge wing.

Hackle:  

Rusty dun game-cock, or badger for a variety.

 

Russell’s Grannom

Another fly from the late Pat Russell who was based in Romsey.  This fly was invent to specifically imitate the mated female which has a green egg sac carried under the abdomen.  Hence the green wool tag – it is interesting to note that Halford also put a tag of green ostrich herl so was probably trying to imitate the same arrangement.

Hook:  

Size 14

Thread:  

Green.

Tag:  

Fluorescent green wool.

Body:  

Heron herl.

Wings:  

Blue dun cock fibres, clipped level with

  

the hook bend (optional to clip them).

Hackle:  

Ginger cock hackle

 

Hair-winged Heron

D.W. Roxborough in his undated pamphlet ‘A Brief Guide To The Hill Loch Fishing Of Gairloch and District ’describes the following pattern (unfortunately not in great detail and with some vital information missing) and also does not give it a name or an originator other than to say it is a local pattern which fishes well whenever there is a hatch of up-wings (Pond olives – Cleon dipterum).  Therefore I have filled in the blanks in the original pattern and given it the name of Hair winged heron as it is the only hair winged fly that I have discovered that uses heron herl as well.  NB – Make sure you Watershed/Gink/Silicone the squirrel hair (but not the body) very well before tying it in.  If I had one improvement for this fly it would be to improve its floatability by tying in an under-wing of CdC below the squirrel.

Hook:  

Size 12 Down-eyed Dry Fly hook (e.g. Partridge TDH The Dry)

Thread:  

Purple (e.g. Uni-Thread 8/0 Purple)

Tail:  

Tips of 4 strands of heron herl.  These are the tips of the herl that are tied in to form the body.

Body:  

Heron herl.

Rib:  

Fine gold wire (e.g. Uni Soft Wire size #33 Small)

Wing:  

Grey Squirrel tail fibres (stacked level and tied in as a hair wing)

 

Grouse Wing Sedge

The following is an Irish pattern to imitate the diminutive Grouse wing sedge, Mystacides longicornis. It also serves also for any other small sedges with grey, light-splashed wings.

 

Hook:  

Size 14 Sedge Hook

  

(e.g. Drennan Simulator Sedge)

Thread:  

Grey (e.g. Uni-Thread 8/0 Grey).

Body:  

Heron herl, ribbed gold wire.

Wing:  

Woodcock, grouse or other brownish-grey

  

feather with pale markings - tied wet style

  

to copy the ‘triangular’ sedge wing shape.

Hackle:  

Coch-a-Bon-Ddu cock hackle –see notes

  

above under Heron & Yellow about

the ‘Mock Coch’.

 

Silver Sedge

Another Irish pattern, this time imitating one of the Silver Sedges most likely, Lepidostoma hirtum.

 

Hook:  

Size 14 Sedge Hook

  

(e.g. Drennan Simulator Sedge)

Thread:  

Olive Green (Sheer 14/0 Olive)

Palest heron herl, or swan herl dyed

  

very pale green, ribbed very narrow silver tinsel.

Wing:  

Any pale grey feather. In this case

  

Jay primary tied as a rolled feather wing

  

tied wet style to copy the ‘triangular’

  

sedge wing shape.

Hackle:  

Ginger cock hackle
