Jan\'s GP - Side View - Here you can see how the foam is folded over the dubbed body, and how the hackle is wrapped through the front segments.

Jan\'s GP - Top View - Notice the position of the wing between the segments, slanting out to the sides much like the wings on a wasp.

In 2003 I went to my first fly-tying lesson with Dave Ryding showing me the basics. Well, I was completely hooked then, couldn't stop tying and tying. Fortunately, I had two awesome fly tying friends, another, Eric Sayer, who sadly passed away. I used to see him two or three times a week. Having learned the basics, I started to experiment with fly patterns, some good and some not so good. You know how it is, the waste bin is a graveyard for terrible flies !

One day, while fishing my favourite water, Barnsfold in Lancashire, which is surrounded on one large side with a good head of pine trees round the reservoir, I noticed quite a few terrestrials being blown on to the water. The trout were going crazy for them. But then as I started to notice what they were, I couldn't make my mind up wether it was a beetle or some kind of Wood Wasp. Finishing my day, I came home and played around for a few days looking to imitate what I had seen previous but without much success.

A funny story came about when I awoke one morning at 3.00am and could see in my head how to tie the fly. One hour later the fly was finished, the greatest feeling in my life, my general purpose terrestrial. I then quickly proceeded upstairs to wake my wife and show her. At 4.00am this seemed a bit crazy to her but I managed to appease her with a cup of tea.

The next day I took the fly to Barnsfold, cast out , and let the fly drift from left to right. Suudenly, a trout hit the fly that hard, I was unprepared and was broken off ! I couldn't believe it so I quickly tied another one on to my fly-line and went out again, within minutes I had a nice 3lb Rainbow in my landing net. Ninety minutes later, I had a total 22 takes resulting in 16 Rainbow, my best ever fishing experience. Frank Casson, who owns Barnsfold Waters, came over and asked jokingly, was i "fishing on maggots" because nobody on the reservoir was catching anything. I gave him the rod and showed him the terrestrial, which he believed was fantastic. He cast the fly out once more and caught a Rainbow himself. He then turned round, laughed, and said, jokingly, "i'm going to ban the fly".

Over the next few months the fly has proved a great success, taking many trout, and which I have given readily to other anglers who themselves have had great success. Many of the flies have found themselves on other waters, ranging from reservoirs to rivers, producing great results. The windier the water - the bigger the fly. It's so exciting watching the trout take them so viciously. They are easy to tie and you can make many different coloured variations and sizes.

Fishing's fishing, and we all know how hard it can be - the fly's not the answer to everything, it's not a wonder fly - but you always feel confident you can take a fish when the conditions get hard.

Please e-mail me and let me know how you get on, good luck, jany@blueyonder.co.uk

Special thanks for their encouragement and help: Bob Petti, Frank Casson, Peter Whittle and Dave Ryding.

Around the same time as Jans GP came out someone was asking about a pattern for Conrad Voss Bark Nymph, a pattern by Mick Huffer appears in Fly Fishing and Fly Tying September 2008 issue on pages 58 to 63 inclusive along with two variations one is a simple tail variation the other a floating or surface attractor. Step by step tying instructions with pictures and a good general write up including how to fish the fly. If you do not know Mick Huffer look him up on Google great tyer, very good fisherman and an all round good guy. Cracking fly works a treat in bright sunshine just about everywhere.
All the Best and I hope this gets to the guy who asked about it.

Thank you

Orion Aon, try the B405 hook it might suit you better, or play around with different types that you think are right for you their are know rules thanks Jan

I don't think that the TMC 2488 is the right equivalent hook. The 2488 is a straight eyed curved hook. I really like this pattern, I'm going to tie some up and try them here in the States.

Hi claudia
the fly works well just left drifting with the wind, or jerking back slow and stopping. Try different ways. Keep intouch Jan

Already said, but this is a wonderful looking general purpose terrestrial. Part wasp, part ant, part anything that flies... Nice generic, neutral brown colors... Can't wait to fish this one...on just about any species that hunts on the surface, both moving and stillwater!! I've been looking for a GP dry and this one definately flips the tippet!

Jan, Nice looking terrestial and well tied giving a good balance, of materials with good floating properties and colours. Have you tried it with "Wonder Wing" wings it looks great same colours as is or white/silver feather, can not wait until April to try it out. It should do well in Canada later on this year.
Many Thanks for sharing this one with us.
