Fly Fishing
White, 12 or 14, very long tail or whatever its called, black head. I ran into somewhat of a hatch of these. Very sporadic. The duns didn't look much different, least I think it was just a spent dun. It was just slightly darker. I used a yellow sally and had pretty good success. it is so much fun fishing dry flies. I need to tie some adams so I can have more success with sporadic hatches like this.
Coffin fly?
Very possible. However, it only had 2 tails. Looking at a picture I took, it doesn't look as white as I thought... But the coffin fly looks almost exactly like what I saw.
Think I found it. Cream Cahill. Maccaffertium modestum is what I saw. I was shocked at how long the tails were, probably around 2 inches. You ever fished a cream cahill stream sayfu?
The long tailed, cream colored fly out West here is the Pale EVENING DUN..called a Pink Albert, or Pink Lady. They are from the genus Epeorus..Epeorus Albertae..2 tailed adults, #12-14 in size. Never great numbers of them coming off, but the fish luv'um. Come off in faster water, and I see them climbing straight up, and the long tails. The body color for the matching dry pattern on my SF of the Snake is a light, pink bodied fly..when wet, using yellow thread, the color will turn to a more lt. tan color. They come off in the mid to late afternoons. I have had some great fishing when these guys come off getting out of the boat, and fishing off a gravel bar making short casts below the head of a riffle off the main current.
Sounds like the same type of bug. I read that cream cahills can hatch from early may all the way through September (different species of course). They are clingers, so this explains why I see soo many nymphs under rocks. So I think this stream has BWO, cream cahills and march browns. Not a bad assortment of mayflies for a stream its size. I'm actually going to be helping with a fish same on this stream this summer. The DNR hasn't stocked it for 2 years and wants to see if any natural reproduction is happening. I can say for certain that it is so hopefully we can get some land owners to agree to some habitat work.
Most likely a cahill(Heptagenia species). All Heptegenia have two tails as adults, three in the nymphal stage. They are prolific, though they seldom hatch in large numbers, they are an important mayfly in the East and Midwest as there always seem to be some around, providing trout with a consistent food source when other hatches are sporadic. I like a parachute pattern to imitate them-spinner patterns also. These bugs are also very attracted to lights at night; leave an outdoor light on in the summertime to see some more.
Where are you from?..sounds like back East. My Pink Albert, Pale Evening Dun is a clinger as well. Many anglers group it right in with the smaller Pale Morning Dun, that is a crawler in the nymph, but it is not..tends to come off after the PMD's come off earlier in the day, and comes off later in the Summer for us..Mid-July into Sept. and extends that light colored mayfly fishing my favorite. A Pink bodied Comparadun can work for both, but the Pink Albert is considerably bigger.
Smerf, maybe you already know this, But troutnut.com is an excellent resource for IDing aquatic insects.
backcast..Thanks for the troutnut site..I've bookmarked that one. Here is an interesting one for those interested in bug hatches. I just read an article by a entomologist that shedded good light on when bugs hatch. It is not by the temperature of the water reached like most think. It is the accumulation of points lets say from the time the egg was laid. A species has so many total points to reach throughout the insects transformation life in the water. Each 24 hr. period a pt. total is credited towards hatching throughout the season. If you had a warmer winter, and the water temp was a few degrees warmer than normal, the bugs point total would be greater giving points for each day in the water. This is why the hatch is not consistent with the temp reached. You can not say they come of at let's say 50 degrees, They come off when the total points are reached, and that can be close year after year, but why it can be off by a week, or two as well. I hope I explained that somewhat coherently. The biologist explained it much better, and the only time I have ever heard it explained in those terms, and very informative.
That actually makes a ton of sense. I did find it on trout nut actually. There is also a very nice pfd article about cahills online that I found. I'll post a link when I get home.
Also, I live in north iowa.

Sayfu, I believe I've read that same paper, or an excerpt of the same. Very interesting stuff. A point made in the literature I read was that the process of "hatching" is set in motion days before the "hatch" actually occurs, regardless of the water temp when they come off. Phenology, the study of plant and animal life cycles, is pretty interesting stuff, and the correlation of hatches and certain plants blooming may be one of the more accurate methods of prediction.
It could happen regardless of the water temp based on the entomologists approach to hatching as the aquatic insect acquires a 24 warm water value every day from the egg on. The total necessary for hatching could be achieved I think at different temps according to the total warmth factor given a quantified number up to that point. I think now that I read it in the first few pages of posts published in Fly Fisherman Magazine. Different posts on different subjects were presented, and this entomologist presented his on why hatching takes place. I have used streamside thermometers based on the magic temp number given me by the experts as to when a hatch would take place..principally the Salmon Fly hatch on the SF of the Snake.
I take it you might be a steelhead guy then? I'm thinking of moving between the john day and the deschutes.
Big time steelhead guy. The most exciting experience I have ever had in all of fly fishing, is to swing a dry fly, or a waking fly, slightly subsurface fly on a dryline and experience the explosion on the surface of a steelhead that rises, and takes the fly....then the discipline of doing NOTHING until the rod tip goes down, and you know the fly is in the steelhead's mouth, as he dives with it. That is an incredible experience beyond belief. I lived right on one of WA best steelhead rivers, and played that scenario out a 1,000 times using 9' 6 wt rods, and smaller steelhead flies that were much like soft hackles in #8 was standard. and often #10's It most often happened in the Fall of the year, low clear water, and very little competition as many anglers had turned to hunting in the Fall. That is where the ability to cast long really is a benefit, and to be able to do it in a routine involving little false casting,...strip, roll out the line, pick it up and shoot it out. Doesn't have to be 80 ft. of line, but 60 ft. is often nice. It creates a much longer fishing arc with the fly moving down and across in front of a steelhead.
