subtle, blue and versatile
Like the Green Bottle Spider in the previous post, the Blue Bottle Spider has a similar application; either as a terrestrial soft hackle pattern, a beetle pattern or as a simple buzzer soft hackle wet fly.
Tying this spider wet fly consisted of tying in the rib first, again using some left over tippet material to strengthen the #14 Uni-Mylar blue tinsel abdomen. I added a fine black dubbing over the abdomen and dubbed up to the point where the black hen hackle was wound. I decided to use a red tying thread for this spider pattern, partly so that it may show through the dubbed thorax in places but ultimately so that it would produce a nice red head to the pattern, mimicking the red eyes of the natural fly.
Fishing the Blue Bottle Spider, it would have similar applications I imagine to the Green Bottle spider; fished either on, in or just below the surface film to suggest a terrestrial or hatching buzzer or deeper down to suggest a buzzer making its way up through the water column. A soft hackle wet fly utilising a slow retrieve or one where the wind and waves fishes it around in an arc, perhaps with the occasional twitch added to the retrieve for good measure. It is a spider pattern that could be fished at any time of the year and I certainly am looking forward to getting out and tying it to my leader this coming season.

I like the dubbing on this one as compared to the Green Bottle. You can clearly see that it makes the hackle stand outward more. That should produce more movement of the hackle tips during a drift. The red head is a nice touch as well.

Thank you for comments, they are much appreciated. A dubbed thorax (or even just a bit of dubbing) behind the hackle does help the hackle fibres to stand outward from the hook shank and produce additional movement. There is a view that a little dubbing helping to support the hackle, is quite important in a river spider pattern as without it, the hackle fibres can become pushed flat against the body of the fly due to the water pressure from the current flowing in the river. Thanks again for your kind words.
