I have used it at Dever Springs in Hampshire to stalk out big rainbows and browns. The technique is simplicity itself, just fish the bug on a shortish strong leader and let it settle on the bottom. When a trout swims close by lift the fly so that it leaves a puff of mud on the bottom. The trout should violently take the bug. It is a surprisingly successful technique.

On river I have used the pattern to fish upstream nymph style with great success for both browns and grayling. On the Upper Avon I use this pattern with a 7ft rod with a double taper floating number 4 with a 7ft leader to fish the pattern upstream. It works very well and I have had some terrific takes using the Frank Sawyer Killer Bug. The technique has accounted for grayling to well over two pounds with brown trout to five pound plus.


Hook: Turned down eye size 14 to 10
Underbody: Copper wire, gauge depends on hook size.
Body: Chadwicks number 477 wool. This is a fawn colour.


1. Starting just behind the hook eye, wind on the copper wire to the hook bend and back. This acts as weight to quickly sink the fly.

2. Use the copper wire to tie in the Chadwicks wool.

3. Wind the copper wire back to the hook bend.

4. Wind the wool back to the hook bend and then back up to behind the hook eye. Make sure that you have used close sharp turns.

5. The third layer of wool gives the bug its shape.

6. Secure the wool using the copper wire on the start of the hook bend.

7. The surplus copper wire is carefully inserted into the wool. This is
most important as we do not want any fish feeling the wire before we
have hooked it.

Conclusion: This is a most effective all-round pattern that is simplicity itself to tie. It is well worth adding to the armoury.
