The animal or Dyret as its known in its native Norwegian is a relatively new pattern, but one that has been embraced by Scandinavian fly fishers with open arms. It’s inventor Gunnar Bingen from Norway developed this pattern for fishing both trout and grayling on the famous river Rena in Norway, He’s quoted as saying, ‘it’s really nothing but a cross between a super pupa and a devil bug” But this offspring of cross breading these two patterns has proven to be a deadly one. Originally thought to imitate an emerging caddis, of which its does so elegantly. But it really comes into its own by pressing all the right buttons for feeding trout when swimming caddis pupae are on the go, from late afternoon and into the night. Night fishing with this pattern under a caddis hatch can put you on the verge of madness, listening for rises in the direction of your stripped fly and striking to sound in stead of sight!
The deer hair used for this pattern should be from the winter coat and reasonably long hair makes this pattern easier to tie giving you something to grab hold of when trimming the head. You can decide what type of head you prefer, whether it be a small tight trimmed one or a large open one that pushes more water as you tug it in. Some tyers prefer to use an extra large hackle so the fibres reach out further from each side. I feel the Dyret fishes best, high and dry, so it should be well dressed with a floatant. I personally like to dress it first with a liquid floatant, give it a good shake and blow off the excess and then followed by a quick shake in a powder floatant. This results in a super water repellant dry fly.
On flowing water I feel it fishes best in smaller hook sizes, using a dead drift method making presentation over rising or feeding fish if possible. Also for searching faster riffles and pocket water just letting the fly drift quickly through possible holding spots is extremely effective. I have also had great success with this pattern on still waters but with short strips across the surface with pauses at intervals were you just let the fly sit on the surface for a few seconds and then start again with short pulls. Its normally at this exact moment the fish will take quite explosively.
When wrapping the hackle, palmer style, don’t make too many turns. If you wrap the hackle too tight along the whole body you may find that under casting it propels, and will twist your leader into the mother of all tangles. This should be avoided at all costs especially during night fishing! Although the original retained the full hackle most tyers now trim it on the underside as in this pattern.
Regarding colour all the olives work well for me from light to dark but many swear by grey and even yellow bodies, for night fishing black bodies or even entirely black flies are the trend. But try your own favourite trout and grayling combinations just as Gunnar Bingen did, you never know you may be on to something!
Hook: Mustad R30 # 10-16
Under body: Natural deer hair
Tail: Natural deer hair
Head: Natural deer hair
Over body: Superfine dubbing
Hackle: Brown or badger cock
Secure the hook in your vice so that the hook shank is horizontal. Attach your tying thread and run a foundation over the whole hook shank to the bend and then back to just behind the hook eye.
Cut a small bunch of nicely marked long deer hair and remove all under fur with a comb. Stack the deer hair so that all the points are even and measure the length of the tail. If you use long deer hair its easier to cut down the head later if you have something to hold.
Once the length of the tail is determined grip the hair with your left finger and thumb and remove the hair stacker. Without realising the deer hair from your left hand make a few tight turns around the deer hair to form the head as shown.
Once the head is secure tie down the body while sliding your left hand back towards the tail without letting go until you have tied down the deer hair all the way to the tail.
Run the tying thread, not too tight, over the whole body. Now you can tie in your hackle at the tail base.
Choose your desired superfine dubbing body colour.
Dub your tying thread and cover the whole body tight in between the head and tail as shown. Finish with your tying thread at the head of the fly.
Wrap your hackle, palmer style along the body with open even turns. Tie off and remove the excess hackle.
Whip finish and cut away your tying thread. Now grip the long deer hair at the hook eye and trim down the head of the fly.
Last but not least, trim off the hackle fibres on the underside of the hook shank as illustrated.
