Whilst (at least for some of us) we are seeing the mayfly appear and the trout start to re-educate themselves into a feeding frenzy, the fish on my local river still tackle the olives that seem to trickle off nearly all day. Therefore, until the fish are properly tuned in on the Danicas, I usually fish a more delicate pattern.
Here is a favourite when the fish are taking olive duns (and even spinners) - the Pearsalls Paradun
Hook: Varivas 2100 Standard Dry 18 - 12
Abdomen: Pearsall’s Silk
Thorax: Fine dubbing
Tails: Microfibbets
Wing: Tan TMC aerodry
Thread: Danville’s Spiderweb
Hackle: Honey Cock
I’ve broken this SBS into two sections so I can post all the photos, including the tie-in of the parachute post…So apologies for the length - I hope it makes sense…
1) Catch in the spider web
2) Select three microfibbets for the tails and snip the from the pack
3) Tie in the microfibbets, taking the thread to the start of the bend. Adjust the length so that the tails are approximately the length of the fly’s body
4) With the tails in place, use your dubbing needle to puch the tails from behind. This will help them to splay apart. Help them to separate and form a forked tail
5) The tails should be nicely splayed now
6) Drop a single wrap of spider web between each tail to secure. I’ve coloured them with a marker so you can see the tips more closely
7) Catch in the end of the Pearsall’s silk - position it so that you will be winding it forwards from the tails…
I’m using the Pearsall’s in a bobbin. You can of course just cut a length which will make the winding easier - but I prefer the to not limit how much I can use for the body, with the minimum of waste (worth any inconvenience in my mind).
Now I wing the fly…here’s my preferred method I use with all my parachute hackles…
8) I like to form the wing before winding the silk body - this allows you to form a tapered body more successfully. Take the spider web through to the position you require the wing. Hold the TMC against the thread under the shank.
9) Pick up the thread with the TMC…
10) Take the TMC to the top of the shank and rotate 180o…
11) Lift the wing up either side of the fly and hold…
12) Secure with the spider web, with a couple around the post to keep it secure.
13) Wax the Pearsall’s
14) Wind the silk to form the body. Try to create a gentle taper.
15) Take the thread to the eye and use a marker to darken the thread - form a head now - since the whip finish will be under the parachute

You can leave this out if you wish - just dub the head instead. I like the appearance of a head though.
16) Add small amount of dubbing of the thread…
And dub out the thorax keeping it slim…
