The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

I caught this tiny larva without a case, but it seems to key pretty clearly to to Glossosomatidae. From there, the lack of sclerites on the mesonotum points to either Glossosoma or Anagapetus. Although it's difficult to see in a 2D image from the microscope, it's pretty clear in the live 3D view that the pronotum is only excised about 1/3 of its length to accommodate the forecoxa, not 2/3, which points to Glossosoma at Couplet 5 of the Key to Genera of Glossosomatidae Larvae.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

It can vary from 14 to 18 depending upon the specific insect and the type of fly. A good crane fly pattern is the one developed by Ross Mueller. It's tied on an 18 and uses over size hackles. You could probably google it and find it

I read somewhere, maybe on this web site, that the adult cranefly is normally of very little importance to the fly fisher. However the larvae is very important as it gets dislodged from its moorings during high water events. Google "Walt's Worm" for a decent imitation.

Here is one way I tie it;



Here is another version with tying recipe for both - photo is a bit dark - but you can get the idea.

I agree that the adult is usually of minor importance however on some streams the fish go nuts for them even though the emergence is relatively sporadic.
Try some yellow soft hackles in 14-18 or an oversized "skater" style dry in 16-18. The takes when they are on these bugs looks like a rise to emerging caddis but more explosive.

Hmmm...

Hey everyone if Mr. W Branch has a couple versions he ties...I don't think it's just for fun or an accident...I think he knows more, about their importance to the trout, than he's completely telling us and he probably has the pictures somewhere to prove it to us! I sense a smile somewhere behind that quote of his above...A knowing smile.

All I know is, it's a rare time indeed, when I sit on a river bank somewhere, that I don't look down at my waders and...Hmmm...Looks like crane-fly larve...There must be a secret out there somewhere that explains how dinky brookies become 10"+ brookies...I think it went something like, "Never let any food pass you by...Or nab it before your cousin does."

Thanks Matt...Now you can explain to the rest of us how you post pictures in the middle of a thread...I always thought you had to go through the "Photo Board"...

By-the-way...What size you tying those things on?

I agree with John on this---I've been fooled more than once. In July look for the hatching fly in the smaller sizes,22 to no see oms.

To tell you the truth I don't know what size those hooks are. I got them years ago and they are the only TMC 200R hooks I have. They are 1.0" long from the end of the eye to the fullest part of the radius on the bend. They look to be about a #12.

I've explained quite a few times how to post a pic in an existing thread. Maybe others know a faster method but here is how I do it.

First you need a Photobucket account, or some other web based photograph storing/sharing site, then when you have opened your "Home" page there will be a window that says "Upload". Go to wherever you have your picture stored (I have most of mine in My Pictures in my computer) and select the picture you want to upload. Then click Upload. After 20-30 seconds the picture will be on your new Photobucket account. There are four dialog boxes under the picture. I have no idea what they say but go to the fourth one and highlight it, then go to the tool bar and click on "Edit", then click "Copy".

Now go back to Troutnut.com and start your post then when you want to insert the picture just go to a space below the body of your post and right click and put the cursor on "Paste". Then you'll see a whole string of alpha characters. At the very beginning you'll see at the end of the string. Just go in and change the upper case IMG characters to lower case and submit the post and the picture will appear.

It is much easier to do than it is to write the explanation.

"At least 4256 species of crane flies have been described. This makes the Tipulidae the largest family of Diptera."

Need we say more? When we think of a "midging trout" or a "smutting trout" there may be a good chance, based on the statistic mentioned above, that he's dining on crane flies...I don't know this for certain, the entomolgist boys will straighten me out here, but I would imagine that the "hatching" process is sometimes similar to the Dipterans and they dangle attached to the surface film and pop out of their "shuck" and onto the surface tension and off they go.

On the stocked pond I fish in April we get quite the midge hatches. There is one that I think everyone has seen which looks like a mosquito and it's antenna looks like two small paddles...I think the slang for them might be "Duck Fly"...Anyway, I have watched them emerge and they look just like one of those slow motion films of a bean pod growing...It comes straight up out of the water until the legs are free etc and then it tips over on to it's legs, standing on the waters surface, and somehow sheds the husk...Trout love them! They motor around the pond sucking them in with their dorsal fin above the water...

Re copy and then past to Troutnut.


I put the two posts together This might help. And by the way this also works for the PM we all send. I deleted some of the letters from above so this would not post a picture.

Spence,
Acouple thoughts
On the number of "cranefly species": I was under the impression that while there is a mindboggling # of these many are terrestrial in nature and therefore not of great importance to us flyfishers.

On the issue of the number of patterns Matt caries I would wager dollars to donuts that they are weighted heavily to the subsurface larval stage.

Some other patterns to tie:
Louis HAiry Honey Bug- Search the archived threads (I have gone to this as my exclusive for any Cranefly larva larger than a #12)
Walts worm- nymph hook of choice #8-18, lead wire wrappped on shank, tan hares ear dubbing dubbed in a cigar shape.
Both of these can be tied with or without bead heads. For me the most important part of these flies is I can crank out a half dozen in less than 15 minutes. I always weight them as I will use then as an anchor fly in my team of nymphs but that is a different thread all together.

Yup..

I tend to think that the sporadic nature of most cranefly emergence is often more than compensated for by the duration of their availability on the water, at least where I've spent the majority of my fishing time, in SW WI and all through the western 3/4 of PA.

Another factor in cranefly importance is that often, some of the most significant cranefly emergences often peak during the so-called "hatch gap" in the first part of May (in PA and SW WI, again...). After the grannom/blue quill/olives but before the sulfurs, etc.

But obviously, YMMV and in general, of course, it is a fly fisher's conceit to assume that most of what we offer up is actually taken by the fish for what WE think it imitates.

To them, it may just look like SOMETHING good to eat and not neccessarily the specific SOMETHING we think they are looking for...:)

My fly box contains four larvae patterns and zero adult patterns. In forty plus years of FF I've never seen a trout come to the surface to eat a winged crane fly.

Hey Matt, you're just fishing the wrong streams, my friend. :) One of the streams you sometimes fish in the spring for olives has seen its pressured wild browns go nuts over dry cranefly patterns in the fall. If you hit it just right. (I just looked and JohnW mentions this phenomena above. I'll bet he and I are thinking of the same stream.) I was surprised by this myself when a friend cued me in, gave me some flies, and sent me there. I had a great couple of days that autumn. I haven't hit it since, and he's had some disappointments other times, so it can vary. I've also taken fish on the J that were feeding on dry craneflies. But that's another story.

Louis,
I have two very specific streams in mind, both of which you and I have fished together and one of which I'm sure Matt fishes from time to time.
Speaking of fishing together I'm getting a hankering for some celery if the weather would just cooperate. ;)

Yes, I guess so, but I'm not about to leave streams that give up at least two dozen over 20" browns each season.
