I have always been a huge fan of the bibio as a bob fly ever since I was first introduced to it as a 14 year old teenager. When the heather flies or beetles are out then this should be getting tied on. Takes are usually savage affairs that occur within seconds of the fly being retrieved.
I add the simple addition of crystal hair to give the fly an extra trigger point. It can make all the difference and allows you to experiment with different colours or lengths of hair for different lochs or times of year. This is one of the easiest ways to experiment with flies and one that has rarely let me down. For more inspiration you can also check out the sparkle kate in the fly tying menu. It is also a traditional fly that has benefited enormously from the sparkle treatment.
Be creative and get a sparkle bibio out there!
Hook: wet fly size 10-14
Body: black and red dubbing (I use diamond dub in this example)
Rib: silver oval tinsel
Body hackle: black cock
Head hackle: red crystal flash (colour can be varied)
1) Whip on some silk and the oval tinsel. Try and keep the body profile level.
2) Add the first part of the black dubbing.
3) Then add the red dubbing.
4) Add the final piece of black dubbing and select a black cock hackle to tie in. Keep the dubbing of the body quite rough - it should look a bit wild. A small brush with a velcro pad can help this if the dubbing is lying flat on the shank.
5) Tie in the black cock hackle.
6) Palmer hackle the fly and lock the hackle at the shank bend with the tinsel. Then wind the tinsel back up to the eye of the shank before tying it off. Try not to "over hackle" the fly. This is a size 10 and the hackle is wound 4-5 times before being locked at the bend. Trim off the hackle and the tinsel.
7) Take a small bunch of crystal hairs (colour of your choice) and tie them in at the middle of the strands.
8) Fold back the crystal hair strands and lock them in place with the tying silk. This doubles the amount of crystal hair and allows it to fan out more.
9) Now the head can be whip finished and the crystal hair can be trimmed. Sometimes the hair works better when left long and straggly and sometimes ..........
10)........ it works better when cut quite short. A tiny bit longer than the hackle is a good starting point for most lochs.
Make sure that the crystal hairs have spread out before varnishing the head. A small drop of varnish at the base of the hairs also helps to keep them in place.
