Also try "sedge larvae" and here is a start using "Trichoptera larvae".

Thanks for the suggestions guys, however, I'm hoping to find
entomology sites rather than fly tying sites so I can find the
pictures of the actual bugs rather than somebody's idea of what the
fly should be.

LaFontaine talks about how he found himself totally at odds with
conventional wisdom caddis emergence. Frankly, I think we
(speaking of the fly fishing community) has done a **** poor job of
understanding the pupal stages of various caddis genera. The fly
fishers of a 100 years ago or more put the time in to learn what works
in the way of Yorkshire wets, etc. but a lot of the patterns today
don't square with what I've read from LaFontaine or from entomology
sites.

As an example, there are a helluva lot of patterns for caddis larvae
but excpet for Rhyacophilia and a few other free swimmers, most
species are net or case so they're not available to trout in a free
drifting form except at dawn or dusk when the biological drift occurs.
Sure the larval flies will take fish but a dead drifted pupa, fished
at the right depth will take a helluva lot more if it's fished during
an emergence.

Nor do we spend enough time with diving females. My very first trout
was taken on an EHC when I was dragging it behind me as I waded
upstream. Hardly the romantic image of one's first trout, but an
object lesson that cadddis don't behave like mayflies. I've since
taken a lot of fish on diving caddis.

Caddis emerge sporadically, rather than as a blizzard, so our window
with caddis is much larger than with mayflies. They hatch over a much
larger period of time, plus they live for weeks in the adult form so
for fly fishers, they offer a lot of opportunities. It's worth doing
the research.

Last year, I put some effort into developing caddis wets with a bit of
success. It was enough to encourage further efforts into producing a
class of flies specifically targeting caddis emergence on either the
swung line or the sunk line. Hopefully they'll take a few fish this
year too.

try http://www.usask.ca/biology/skabugs/caddis/trichop.html . There is a
picture of a pupae on this page. Pictures of caddis puape are not easy
to come bu; there are a few in the aquatic insect texts I use. I think
the photo on the above link is pretty representative...they look lke
like fat larvae with stumpy wings anbd long legs.

That is my impression also ... and correct me if I'm wrong but I don't think
entomologists would seek out the pupa for identification purposes so they
are more likely to have pictures of cases and larva

Good images, even a good real time, head bent to the water, glimpse of any
of the transitional
periods of emergence are damn hard to come by ... harder than troutG

You can cut pupa out of cases and get things that look like
the picture in Tim's link. "Caddis and the angler"
has a picture or two, and there are Schwiebert's drawings in
"Nymphs" All look much the same in basic form. The only "in the water"
pictures I have are in "Emergers" by Swisher and Richards ... and they are
very poor and B&W but suggest exactly the same form.

But the question is if that is what they look like when available
to the fish. As you know, LaFontaine and others say "no" that a big shiny
bubble is more like what the trout see. I have never been able to
confirm that, and have never seen anything 'real' that actually looks
like a sparkle pupa or Iris caddis etc but I've never SCUBA dived and
tried to get the fish's eye view.

Let us know if you find any good pictures, Peter, of emerging mayflies too,
if you happen on them.

Oh, and I have seined small cased caddis from the daytime drift on a couple
spring creeks ( near the surface!) and Lawson and Harrop both report
fish "rising" to them on the HFork, although I've never been able to confirm
that...... To me this remains like floating snails, I've seen 'em, the
'experts' say trout eat 'em, it makes sense, but I ain't caught a fish on
one yetG

Thanks Tim. This page has one good picture of a pupa but they don't
identify it. I figure some combination of ginger and brown works for
most pupa except the black species.

My experience, and I always feel compelled to point out that it's limited,
indicates that pale olive and a yellowish ginger produce best during
hydropsyche time. If you catch freshly emerged adults they tend towards
these colors ( sexes different colors? ) but most of what you'll snag from
streamside weeds will be brown bodied, they seem to dull up after a short
period.

Obviously, one of the biggest reasons for coming up with your own patterns
is to match LOCAL bugs better, so YMMV

You and Mike mention shrouded patterns. Mid-June the caddis some on strong
on the Firehole. Last year, a wide variety of circumstances, mainly a bad
knee, had me wanting to fish downstream on a swing. I loop dubbed a fat
pale green or pale ginger body of Antron blend and lightly brushed it to
make it rougher, applied a very sparse downwing style wing of similar
colored Antron yarn ( looped around thread for durability ) and combed it
out over the top of the body. This 'wing" then looks little like a wing,
it's very thin and reflective ... think negligee and you get the ideaG .
Next somes a couple turns of partridge. Now add two or three wood duck
fibers on top and trailing backwards, rather long, cover the tiedown area
with some muskrat ( I bought a whole skin, so muskrat finds it's way into a
lot of my ties ... hares ear might be better ) I had better luck with
some tied with a black bead, but unweighted produced well, too. Treat the
thing with watershed ... fish it down with a reach cast, rather like a
spring creek dry presentation ... maintain just enough tension to feel it
then as it gets to the end of available line, let it swing.

This pattern produced VERY well at times, and was nearly useless at others.
This leads me to believe that trout were taking it "for" something when they
ate it, rather than just being attracted and thinking " might taste ok" My
assumption is they ate it as a hydropsyche pupa, but who knows. Fresh flies
alway worked better than soggy ones, and two or three casts without a take
was reason to change, or maybe FrogFanny.

On the West coast a Bird's Nest treated with powdered floatant and fished
with splitshot is very popular and effective. The artist in me
appreciates this approach ... i.e. actually having real bubbles on the fly
.... over the shiny stuff that looks like bubbles approach .... a mixture of
the two might be the best, and that is kinda what I tried for, get bubbles
to cling to a fly with a sparse amount of shiny stuff in it.

I'm glad to hear Mike say he saw what LaFontaine reported ... my own caddis
emerger efforts, and I've gotten a couple 'famous' tiers to admit the same
of theirs, come from trying to imagine what a pupa would look like with
bubbles because "they" say the pupa have bubbles. Until I actually see it
myself, I'll still wonder if the sparkle isn't more attractor than
imitation, I guess

It is not particularly difficult to observe this. You need a tank, ( quite a
small one will do, even a large jar), some larvae, and patience! One can
see the effects quite easily.

One also does not have to dive, ( I have not been diving for years, I feel
too old for it, and my bones don´t like the cold anyway!) one may use a
periscope. These are easily built from plastic pipe. Square pipe, such as
is used for central heating convection, or cooker hoods etc is better than
round, it is easier to fit the mirrors. You still need patience of course,
and a good idea where the beasts are ascending!

The effect is not so much one of isolated bubbles, but of one large silvery
bubble, which reflects the surroundings, and the basic colour may shine
through somewhat. When I first read Fontaines´s findings, I was very
excited, pleased that his results so closely corresponded to mine, and
immediately tied up the patterns, but unfortunately, they did not work very
well for me. My own patterns were better. I have no idea why this should be
so.

Lastly, when the pupae are ascending, they do it quite quickly ( at least
the species I managed to observe did), and they also hatch amazingly
quickly. The trout still pick them off, but they have to be quick, which
often means fast slashing takes. This of course also depends on depth and
speed of flow.

Sometimes movement ( a lift!) helps, sometimes it does not seem too.

The "shrouded" patterns were my best bets in most cases, and usually mixed
light brown ( hares ear colour!), with darker "wings" etc. Often it is very
difficult to determine which species is hatching, but the shrouded silver
patterns tend to catch anyway. In my opinion, on most European streams, the
caddis is far more important than mayflies, and also has a much broader
hatch window. This may also be true of some American streams, but of course
I am only guessing that.

Indeed, were I limited in any way to patterns, I would feel quite confident
on practically any stream, with a range of midges, and caddis.

I've seen some video of the silver bubble taken in a tank. I always
wondered if an object lit from the side and photographed from the side would
look the same as one lit from above and observed from below ... closer to
trout's view. I guess I could try getting a tank, maybe I will. Most of
the fishing season I live in a travel trailer and an aquarium is out of the
question .... and I'm not sure how I'd cool and oxygenate a jar, either

That was the impression I had ... rather like a waterboatman, which I have
seen

I've never had good success with any of his caddis patterns either, and I'll
admit that is one reason I'm glad to hear your observations match his. Two
of my life's passions, dog training and fly fishing, both have lots of
literature, lots of pretend science, and lots of misinformation, passed on
for generations in many cases. In the dog training area I personally have
known 10 or 12 published authors, and their dogs, and can testify that only
one of them could consistently train a hungry dog to eat. Some of
LaFontaines ( not to speak ill of the dead ) theory's, in several of his
books, seem better able to sell books than qualify as science


My own patterns were better. I have no idea why this should be
so.


I know .... as I posted earlier .... confidence is THE most important
material in any pattern



Indeed, were I limited in any way to patterns, I would feel quite
confident
on practically any stream, with a range of midges, and caddis.


The midges for sure ... my caddis knowledge and faith increases each season.
I have knee surgery soon and I'm hoping it will allow a little more variety
in the types of water I can painlessly fish. If so, I'm certain to spend
more time tossing caddis ties. BUT, and I'm sure you know this Mike, but
others may not ... 'soft' rivers like Silver Creek and the ranch section of
the HFork, famous for mayfly hatches, are often "tough" simply because the
anglers refuse to see the caddis everywhere ... a mistake trout don't make.

admitted, but has LaFontaine's sparkle pupae been improved upon??
The colors might be tinkered with a bit, but a lot of what a fish seems to
see of pupae is brightness and reflected light.

Nor do we spend enough time with diving females. My very first trout
was taken on an EHC when I was dragging it behind me as I waded

taken a lot of fish on diving caddis.

I'm convinced many,if not most, of the trout I've taken on traditional
winged wets we due to trout looking for diving female caddis.

.. It's worth doing
the research.

It's damn near a religion to do so where I live.....the Tulpehocken is a
tail water, and as such, has a lot of different caddis of all sizes.
Imitation of them at several stages is a necessity to succeed much of the
season.

Last year, I put some effort into developing caddis wets with a bit of
success. It was enough to encourage further efforts into producing a
class of flies specifically targeting caddis emergence on either the
swung line or the sunk line. Hopefully they'll take a few fish this
year too.

Have I unloaded any Submergers on you?? If not, remind me at Penn's.
Or, as an old Jefferson Airplane song was titled, "Something of Value will
come to you Shortly"(or, something like that). At any rate, I want you to
give me an A/B trial with your technique versus your emerger and female
diver imitations. You might like them.
