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.

Limnephilus (Summer Flier Sedge) Caddisfly Larva Limnephilus (Summer Flier Sedge) Caddisfly Larva

Case view of a Limnephilus (Limnephilidae) (Summer Flier Sedge) Caddisfly Larva from the Yakima River in Washington

This seems to be a young larva of Limnephilus. Although not clear in the picture, several ventral abdominal segments have chloride epithelia.

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 fished the south branch of the Ausable river Tuesday, water is still high and cold, but I managed. Not much was going on in the morning, I tried the euro nymphing rig but couldn't get much going. As I worked a different stretch of stream, caddis started to emerge, and then also some hendricksons. the caddis were like snow blowing up the river, it was really cool! I could have watched that all day long, as it was I got lucky and this spot had a 6 or 7 fish rising, I got 3 decent browns on a x2 caddis. These fish were really spooky and it took a lot of cast and just watching, which was great! I have some pics but have to see how they look on line.

Adirman, no im sorry im lacking in my bug identification, im working on that though! I will try and make a effort to capture some bugs next time, I need some sort of net to carry with me as I have pretty poor luck trying to get them by hand or my hat.

I ran into a huge caddis swarm in northern WI at the end of the Hendricksons hatching. I caught several and sent photos to a MI aquatic entomologist. It is believed to be Glossosoma spp.. Little Gray Sedge. The small female caddis had a huge green egg sack. I have the specimens in a vile to get positive ID made when I have time.
