Hi there, I've been hunting the internet recently for instructions for a net buidling caddis pattern but with no luck. Has anyone ever stumbled across one or have a link they could send through? This is what I've come up with but would be keen on seeing actual instructions to see how I can get it looking better:

Looks good to me mate the only thing I might do to that is rub it with a bit of hooky velcro to make it more fuzzy.
Nice fly.

Thanks guys.
Steve, do you mean rub the underside of the fly? Particularly the white part?
Thailand....do you fly fish much there? What types of flies are used over there? I'm contemplating a move to asia next year - what are the fishing prosepcts like over there, is it hard to find a river that is not polluted and brown? I'm looking at Shanghai, Hong Kong, Singapore or the dream would be Vietnam.

One thing to remember is that often the slimmer the fly, the faster the sink, and more realistic the prey image will be.
Its a fine line between fluffing out the dubbing and maintaining an efficient sink rate.
I use a simple '2 minute' tie of sparse green dubbing over lead, with a caddis green flexi floss rib, and a long, black thread / floss head. For extra heavy suckers, two or three small tungstan beads may be employed in lieu of the aforementioned head with just a sparse dubbed collar to suggest legs / movement.
If you wish to tie a more imitative pattern (this tie does look pretty good) then whip down a sliver of thin skin to the top of the abdoman beneath the rib.
You pattern looks like it will work well.

| That's a very nice fly Brendon. Can't really fault it at all - I have tied a similar pattern and it does work. However, for whatever reason I find that a simpler and scruffier fly works better! So now I just tie a green/olive dubbing blend at the back, and a charcoal/hare ear blend at the front, ribbed with copper wire, and roughed up a bit. Takes about 2 mins to tie one. Has worked well for me in plenty of waters with high net-building caddis populations. Go figure..... |

Maybe it's just my ancient old eyes Chris, but I'm pretty sure he has a full wing case over that body as it is.....
It looks fine to me and will get eaten for sure. Chris is right about fluffyness impeding sink rate but easily solved by swinging it off the back of a tungsten bead nymph or for that matter tying a tungsten version as well. ------------- http://www.clarkreid.co.nz" rel="nofollow - www.clarkreid.co.nz FFF Certified Casting Instructor / Umpqua Designer Tier

Thanks for the feedback upstream - good to hear it at least looks like it imitates something! Like the sound of a quicker fly, so your version, do you not lay the scudback over the top? Just keep it open and a bit rough?
Got to get some good green dubbing, I like the colour of the Umpqua net building caddis but haven't been able to find green dubbing of a similar colour to theirs. Most of the stuff I've found is a bit bright - probably more of an actual olive colour than what umpqua use. What brands/blends do you use?
And Clark yep it's got scud back on the fly - just didn't want to insult Chris by saying so, clearly you're far more comfortable doing it! Tungsten version of the fly is the next thing to tick off the list.

Hi Swine Hunter,
Are you able to get the photo of your caddis larvae back up here?
How have your later ties gone and can you post photos of these as well?
What about caddis pupa emergers, are you tying these?
Thanks,
Tim.

Sorry about that, changed all the permissions on my Flickr photos and it must have dropped off by mistake. I have tied a few more of these and am now aiming for a little less dubbing than the one in the pic, making it a slimmer pattern. Had success with the slimmer flya couple of weekends ago on the upper tongariro - have posted these pics too...
FYI the materials I use are from Steve's flyshop:
Caddis Cream Dubbing: http://www.flyshop.co.nz/product/mottled.html - http://www.flyshop.co.nz/product/mottled.html

Scud Back: http://www.flyshop.co.nz/product/bmscud.html - http://www.flyshop.co.nz/product/bmscud.html
Fly below tied on TMC2457 #14
Haven't tied any caddis pupa emergers, but once I get some time (when work calms down) I'll probably give them a go.
#14 white caddis
 and the fish that were fooled the other weekend:

Thanks for that and it's obviously doing the business for you. The Aoteapsyche specimens I’ve seen look quite dingy in colour. Many of the commercial dubbings available are bright and full of glistening fibers. Even black dubbing can shine like coal and the naturals aren’t like that. Hydrobiosis is a brighter green and might be a fatter chap. What do you think? Either way, I know trout wouldn’t turn up their snouts for one over the other and your imitation looks good.

The point of sparkle in dubbing is that when it refracts light it gives the appearance, underwater, of movement. Many fly tiers will incorporate a glister or masterbrite type dubbing into a fly not because of any reflective iridescence of the natural but it an attempt to imitate movement. Many believe this is a major trigger for some wary fish. ------------- http://www.clarkreid.co.nz" rel="nofollow - www.clarkreid.co.nz FFF Certified Casting Instructor / Umpqua Designer Tier

" Many believe this is a major trigger for some wary fish"
It's a trigger alright but I'm not sure it always makes the fish move in the right direction.
How has your hunt gone for other dubbings Swine Hunter? This is great detail for a #14. What are your #10s looking like. Got some new photos?

I'm pretty happy with the cream caddis dubbing used on the fly in tha image above so am sticking with that. I am get to find the 'perfect' caddis green colour, many of the materials seem to bright. I like the colour of the Umqua green net builder but can't find that dubbing material anywhere. Haven't tied any #10's, mainly stick to the medium-smaller flies.

Have you tried the squirrel dubbing? One that isn't too bright and is a nice caddis colour is Golden Olive. It seems to go a little darker too when wet and brushes out well for that bristly life-like look.
For really fine and drab dubbings there is Fine and Dry Dub from Feather Merchants. I picked up a new one this morning. For body material, the colour is good but with velcro they tend to fluff out rather than spike out. What about seals fur for legs and thorax?
Is there much difference between your Metz Scud Back and Thin Skin?

Nope, haven't tried squirrel; might keep an eye out for the Fine and Dry Dub - could be worth a crack to get the colour right.
Haven't used Thin Skin sorry so can't comment. Metz Scud does the trick for me.
