Artistic view of a Male Pteronarcys californica (Pteronarcyidae) (Giant Salmonfly) Stonefly Adult from the Gallatin River in Montana

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

Case view of a Pycnopsyche guttifera (Limnephilidae) (Great Autumn Brown Sedge) Caddisfly Larva from the Yakima River in Washington
It's only barely visible in one of my pictures, but I confirmed under the microscope that this one has a prosternal horn and the antennae are mid-way between the eyes and front of the head capsule.

I'm calling this one Pycnopsyche, but it's a bit perplexing. It seems to key definitively to at least Couplet 8 of the Key to Genera of Limnephilidae Larvae. That narrows it down to three genera, and the case seems wrong for the other two. The case looks right for Pycnopsyche, and it fits one of the key characteristics: "Abdominal sternum II without chloride epithelium and abdominal segment IX with only single seta on each side of dorsal sclerite." However, the characteristic "metanotal sa1 sclerites not fused, although often contiguous" does not seem to fit well. Those sclerites sure look fused to me, although I can make out a thin groove in the touching halves in the anterior half under the microscope. Perhaps this is a regional variation.

The only species of Pycnopsyche documented in Washington state is Pycnopsyche guttifera, and the colors and markings around the head of this specimen seem to match very well a specimen of that species from Massachusetts on Bugguide. So I am placing it in that species for now.

Whatever species this is, I photographed another specimen of seemingly the same species from the same spot a couple months later.
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.

I might be in Luther, MI for a weekend conference in late June. If I go a day or two earlier are there any trout streams close by to wet a line in?

I have never trout fished in lower Michigan. Plus, it will be my first time taking the Badger Ferry across the big lake to Michigan.

Any ideas please PM me.

Thank you,
Detroit, MI

The Little Manistee is close to Luther I believe (I'm not as familiar with the west side of the state). I have never fished the Little, but I have heard amazing things. There is a flies only stretch and would be worth exploring!

Like doug I fish the east side for the most part. I have fished the upper Manistee near Deward. This is smaller water that is accessible, very pretty area. There is also a Pine River in that area that is well known for its brown trout fishery, and also for its canoe trippers! If you can get your hands on a copy of Michigan trout streams it is very helpful with river locations, near by resturants and hotels, and other info.

Little Manistee starts in Luther.

Baldwin R is just south of you. This is an unmentionable on some forums.I feel the Michigan people here know about this already.

Of course, the PM is a short drive away.
