Time Fished: 430pm - 745pm

Weather Conditions:Mostly Cloudy with periods of sun, 75-76

Water Conditions: Temp at 7pm was 60 degrees It was stained a brown color but that could be normal

Insects: A few Sulphurs hatched at 545pm caddis began to show up at 7pm, a coffin fly made an appearance about 6pm but that was the only one I saw

This was my first time on Penns and I wanted some room to roam so I fished between Coburn and Spring Mills. I knew it was green drake time when the first 3 cars parked streamside were from NJ, Ohio and VA. I picked a location away from everyone else. There was virtually no insect activity when I started and I only saw a few rises.

I used nymphs for a while in the couple holes where I started but I really like streamers so I fished them most of the time. I caught 2 on streamers (1 brown, 1 brook) and had about 12 strikes.

Since there were no rises in the last 45 minutes before dark I decided to hop in the truck and check things out below Coburn. After rounding the S turn I could see the cars lining the road ahead. I stopped where the creek runs along the road and fisherman were lined the whole way down the riffle. Coffin flies were in pretty good numbers and I caught several, for samples, that were landing on the road.

The body measurements from the from the mouth to where the tail begins was either 10/16” or 11/16” depending on the fly being measured. I matched it up to some hooks and I tie coffin flies with a Live Body white tube that extends just past the bend of the hook. A standard size 12 hook seems just right. Maybe even better are ones my father ties on a short shank wide gap hook. Despite the short hook, the Live Body length extends to be a perfect match to the Penn Creek sample length. Which tells me the Coffin flies on Kettle Creek are same size as the flies on Penns. Most coffin flies are tied too large which may not make a difference to the fish but it certainly will impact your hook up rate.

After my little scouting mission I drove back upstream to survey the water. No rises so I tore down my rod, took off my waders and as I was lacing up my shoes I heard the first rise. Then another. I stood and watched about a half dozen fish become active and maybe as many as 12 in a short stretch. So the spinner fall was late.

I was not disappointed I missed this late surge. I was happy to watch it from the bank. My day started at 430am because I never fished central PA so I started the long drive in the dark and I ended it watching rising trout on Penns in the dark. I was able to land trout on both Big Fishing Creek and Penns Creek. Got to see some Coffin Flies dance over a famous riffle and I still had the next morning to hit one more stream before my weeklong trip on Kettle begins.

One observation I have on both Big Fishing Creek and Penns was how trusting the wildlife was. On Big Fishing creek I walked within a rods length of a chipmunk feeding on log. I stopped he looked at me then went back to his business rather than flee or just be on high alert. On Penns a tree swallow landed 20 feet from me while I fished on a gravel bar. He picked some grit for 20-30 secs and then took back to the air. Later I was eating a streamside sandwich along Penns and a flicker landed across the road from me to dust in the dry dirt. He never paid attention to me. These occurrences are rare in NW & NC Pa, yet I see all three in the same day in central PA.

Another observation was the abundance of game only trails. Where I typically fish every trail along a stream has boot prints. Here I’d see a trail and assume it led to a good hole and sometimes it did, but most often it was just a game trail with deer tracks and raccoon track. There sure are a lot of racoon down there.
 
I was one of those many guys at Coburn the night of 6/2. Had my son in law with me who is new to flyfishing. Needless to say he was most impressed by the squadrons of coffin flies in the air, and in our hair, mouth etc. He even caught a decent brown on a GD and another on a spinner. We were fortunate enough to have some trout rising as it was getting dark, and we caught the beginning of the spinner fall about 9:30 but didn't have much luck connecting so we left. I haven't been to Penns for a number of years, but am happy to see the bug life looks as good as ever.
 
With all due respect Prospector, you were likely not looking at coffinfly spinners if they were “10/16 or 11/16 of and inch long”. Males are larger than that and females are larger than males. Could you have been looking at another spinner?
 
Could have been Sulphur spinners. Size seems about right, and fish (especially ones in Penns) seem to like them better, or more accurately perhaps, find them easier to catch and eat than MB's or GD's when they're all there simultaneously.
 
They are all just bugs! Big, little, dark or light. I was at Poe Paddy 6-03-1208 and the water was carpeted with bugs at dark… No fish rising. Campground empty. I left today 6-06-2108. It should be on fire tonight!!!
 
DaveS,

I’d post a few pictures to show you what I’m seeing (but I can’t figure out how to do it and just burned an hour trying). I do know what a coffin fly is. It can’t be mixed up with anything. I’ve been fishing the hatch and spinner fall for nearly 40 years. Some of the ones I caught on Kettle were actually bigger than the ones from Penns. 13/16 vs 11/16. To do it right I really should gather and measure 100 of them to remove the natural variability but point is everyone thinks they are bigger than they really are and a fly the actual size fits better in more fish’s mouths.

There are a couple threads in the Site and Forum Comments forum that explain this (if you haven't already reviewed these). Photobucket does not work with this site anymore.

To upload a pic directly on to the site, which is how I do it, you first need to reduce the photo's size using whatever photo editing software you have (I use Paint). About 150kb is the max. Get the pic under that size on your computer.

After you have written your post, then you want to click in the "attach file" box, or "Browse" below where you're writing. Find the image, then click on it, then click "open"; then click "upload", then "submit."
The key is to get the photo under 150kb.
 
Prospector, feel free to e-mail a pic if you’d like. I’ll post it.

We’re both about the same fly fishing vintage, but something about the size of your spinners isn’t jiving with my memory and a fair amount of reference material.
 
DaveW, thanks for the advice on adding a picture.

Here are some of the pictures I took of the flies I collected

Pictures are:
-- Penns Ck Fly with sz 10 hook; this picture was taken 23 hours after I collected the specimen. Note the particular sz 10 hook I used matched the insect size from mouth to end of abdomen. Unfortunately I didn't use my ruler. This was the largest of the 3 coffin flies I gathered just south of Coburn

-- My Pattern & sz 10 hook with ruler; This shows the length of the sz 10 hook from eye to bend and you can see it comes in at 11/16". You can see both the hook and the fly pattern are the same length. This gives you 2 photos to confirm the length on the actual coffin fly is 11/16"

-- Penns Ck Fly with my pattern & a sz 12; The pattern is tied on a wide gap #14 with the length to match Kettle Creek Coffin Flies (where I fish most) and interestingly that length nearly exactly matches the specimen from Penns. The size 12 hook shown would also be a good choice for this pattern

-- Kettle Creek Coffin Fly; This specimen was measured 12 hours after being collected. You can see it measures 13/16"

-- Penns Ck Fly with someone's huge pattern; My father ran into a fisherman that gave him this pattern earlier in the week. You can see the pattern is 50% larger than the actual fly.

Sorry, I'm late getting back to this:
Prospector, I can't dispute what your pictures show. However I do wonder if the insect is shrinking 23 hrs later due to dehydration.

From my literary library, "Hatches II" (Caucci, Nastasi) list E. gutulatta as having a size range from 18 to 30 mm.

From my insect library, I have a specimen collected from Poe Paddy, which roughly measures 1.09". I resisted the urge to remove it from the bottle to get an exact measurement. (approx. 27mm)

I have encountered the Green Drake hatch in varying degrees on several freestoners, the Delaware system and of course the central PA limestoners. It has always been my casual observation that the Penns Creek bugs were the largest, or at least equal to the other central PA streams of note.

Perhaps I need to make room in my vest for a set of dial calipers.
 
I agree, the length of time may factor in. I collected them at sun down when it was about 71 degrees. Left them in the pill bottle in my vest in bed of my truck overnight under Tonneau cover. They likely survived much of the night. Next morning it was in low 60s when I fished at Fisherman’s Paradise in pouring rain for 4 hours. Then it rained on Kettle most of the afternoon. So the air was moist.

It would have been best to measure them right away. I wasn’t real concerned since I wasnt dealing with scorching temps. Plus the one I have pictured doesn’t look too dried out.

But next time I’ll gather more and I’ll measure them sooner. I always put them in fridge to cool them down so they stay still longer.

One thing to remember, the one from Penns and the one from Kettle were the largest of the 3 I gathered from each stream. I’m certain there were smaller flies than these since I had them in hand. By the same token there undoubtedly were larger ones too. But I believe these are the more representative samples of the general population.
