I've been told the Little J has a very good Grannom hatch. When I look at pictures on this site I see photos of what I call the "Apple Caddis" which are very common on the West Bracnh and main stem Delaware. The Grannon I remember emerges on the Beaverkiill in huge waves about every half hour and has a mottled, or variegated, wing and a brownish body with a green egg sack. I've been told there is a description of this fly in LaFontaine's book "Cadisflies". Below is a picture of what I would call a Grannom. My question is if I'm going to tie pupa and adults for the Little J which of these two bugs is the predominant caddis there?

Matt-

Although I've never seen a caddisfly exactly like the 1st photo, the wing patterning resembles that of Hydropsyche (Spotted Sedge).

To me at least, the 2nd photo looks more like Brachycentrus (American Grannom or Mother's Day Caddis).

Of course I realize this doesn't answer your question, but perhaps it will be of some use to you anyway.

The Androscoggin River in NH has a huge emergence of the upper fly The locals call it a Grannom but it is most likely the Spotted Sedge you refer too. I'm sure you can understand why I need clarity of the Littte Juniata Caddis since there is such a sinificant difference between the Apple Caddis and this fly. Thanks for your reply.

Gonzo helped straighten out the Grannom issue in a really good discussion we had last year that should clarify some of this.

Mike-

Well, as long as you asked, I guess it could be indicative of some form or paranoia. Is that the information you sought?

Thanks to everyone who tried to steer me in the right direction to the prior extensive discussion on these bugs.

Matt, I'm glad Taxon has such a long memory. I'd almost forgotten the thread he linked to. It should give you most of the information you need. A dark charcoal, black, or dark brown body works for the adult. I've seen patterns by local fishermen who do very well and they all seem to use a slightly different color. Everyone I know of uses a dark wing, some deer hair, some dun CDC, some a combination. Every possible style of caddis adult gets pitched at the fish, and all seem productive. As it is some places the first hatch of the season, the fish are a bit less picky, than they are for something like sulphurs. One thing people do for any difficult fish they run into is tie a bright green egg sack, which I believe also serves as a "hot spot" attractor.

Louis-

I suspect it's Jason's long memory to which you are referring, as he is the contributor to this thread who posted a link to another thread.

Yes, I see. Posting too quickly and because I had just read several posts by Roger, I mixed the two bug experts up. Sorry Jason, credit to you for this one.

Now a question to all the bug experts. Reading Caddis Superhatches by Richards, I believe, I came across the observation that in the afternoon Grannoms swim underwater to lay their eggs. If this is so, I may have been missing some great wet fly action. Does anyone know about this, particularly in reference to the Grannoms we'll see hatching in the Little J, Fishing Creek, Penns Creek and other PA streams in about a month?

louis, I'm not a bug expert but the females are divers (at least on the streams i frequent..."J", spruce, etc.) and that is the reason that the grannom dries in my box, serve mainly as a strike indicator for my pupa. Try a peacock body wet with a flo. green tag.
