The thread underbody is best tied to form a cigar shape and has the added bonus of fluorescing, giving the fly a curious hue. Slim and compact this is the ideal pattern to search deep water. A coat of varnish for protection.
Hook: Grub size 10-14
Weight: Adhesive lead foil
Underbody: Fl Chartreuse UTC 140 thread
Abdomen: Olive flexi-floss
Thorax: Hare’s fur
Thorax Cover: Black thin skin
Fix the hook in the vice and wind close turns of thin lead strip over the abdomen region. Secure with turns of tying thread.
Position the tying thread just in front of the lead strip and catch in a strand of olive Flexi-Floss. Wind on close turns of thread to secure the floss.
Wind thread to bend then, applying it in layers, create a tapered abdomen. Apply the Flexi Floss in evenly spaced turns over the abdomen.
Secure the end of the Flexi-Floss with tying thread and cast off with a whip finish. Apply a thin coat of clear varnish to stop the rib slipping.
Once the varnish has dried run on black tying thread at the front of the abdomen. There, catch in a strip of black Thin Skin, dull-side up.
Apply a small pinch of dark hare’s fur to the thread and dub it on to form a thin rope. Wind on three or four turns to create a slim thorax.
Take a brown partridge hackle and remove the tip to leave a V-shape. Catch this in just behind the eye so the fibres are either side of the thorax.
Stretch the Thin Skin over the top of the thorax and secure it at the eye. Remove the excess Thin Skin and hackle stem and cast off the thread.
