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.

Holocentropus Caddisfly Larva Holocentropus Caddisfly Larva

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.

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.

Made use of my fresh MI license and found myself a patch of water to cast on for a little while. After some exploring on 2-tracks, I popped down to the Pine Acres access on Cooke Pond today, and there was no one there! No fees today either, the fee box was wrapped up tight in plastic...saved 5 bucks! Nice sunny day in the low 50s F but the wind was stiff and on occasion made casting frustrating, and nothing came out to play with my #10 black-eyed POG Bugger either, in spite of some decent looking wood on the (strangely weedless) bottom (I am usually here in the summer). It's early yet...heard the first frogs today, northern leopards were calling at Pine Acres from the grassy islands in the river! Saw several mourning cloak butterflies as well as a couple of angle-wings, midge hatches at Cooke Pond too. Felt good to be out in the woods and on the water, fresh air, sunshine, and exercise, and no people to deal with...except for two brand-new looking cars at Clark's Marsh that (again) made me turn around and go home.

It has begun...slowly...

P.S. That #10 POG Bugger got left behind me in the weeds somewhere on a cast (my last)...1st sacrifice of the year, too.

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
