The following pattern has a detached body made up of either dyed deer hair fibres or white deer hair fibres coloured with a marker pen to obtain the desired colour. To create the body, put the deer hair fibres into a deer hair stacker to get the fibres level and then insert them onto a dubbin needle or thin metal rod that is attached to your vice and horizontal. Catch in the thread onto the deer hair and wrap from the thick end down to the thinner end, perform a few wraps on the thin end and return to the opposite end, Whip finish, trim away the thread and slide the body off the needle. You can see the thread wraps in the image of the fly above. Detached bodies are readily available to purchase if you feel you don't want to create your own, you can also use foam in place of the deer hair.
Catch in a bunch of pheasant tail fibres, secure with thread to a position opposite the barb and then run the thread back up to a position about 1/4 length of the hookshank from the eye. (If you require a rib, this is the time to catch one in to the underside of the hookshank and continue it down to a position opposite the barb, then return the thread to a position about 1/4 length of the hookshank from the eye ).
Wind the pheasant tail fibres up the hookshank and secure at the position about 1/4 length of the hookshank from the eye. Trim waste. (For the rib, wind the wire up the hookshank in open turns in the opposite direction that the pheasant tail fibres were wound, secure with thread and trim waste wire by rocking from side to side)
Catch in 4 knotted pheasant tail fibres for the legs about 1/4 of the hookshank length from the bead, can be tied below or above the body, your choice and then a further two legs facing forwards in front of the eye. Trim the waste pheasant tail fibre ends.
