Hex Mayflies
Hexagenia limbata

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.

Limnephilidae (Giant Sedges) Caddisfly Larva Limnephilidae (Giant Sedges) Caddisfly Larva

This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

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.

Bald Eagle Caddis

There are grannoms aplenty in the Bald Eagle, however by May 20th there are no grannoms on any of our central Pa streams. More likely Ryacophila (green rock worms)size 14/12, which can emerge throughout late April and May, or Hydropsyche,size 16/18 with a tan wing and a cinnamon body. The trout behavior you describe is common on the Little Juniata. In either case, fishing a pupa in the film is the way to go, especially for Hydropsyche. They spend hours struggling in the film before emerging.

Bald Eagle Creek Hatch

I was on Bald Eagle Creek around Milesburg last year in May. It was mid morning and fish were rising everywhere. I saw caddis in the air but the rises weren't splashy. Every caddis pattern I tried, fish would rise to and refuse so I'm fairly certain they were taking caddis. Do the trout up there get selective to egg sac or spent wings because they were the only types I didn't have to try. I'm not even sure they were Grannoms, so does anyone know what other caddis hatch around May 20th? This year I'll be there from May 12 to 19, so any ideas would be terrific and much appreciated. Thanks George.

Looks like a Brachycentrus female. Check out the kink in the forewing just at the stigmatic area in pic 4. Pics are great!
