Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Holocentropus Caddisfly Larva Holocentropus Caddisfly Larva

Dorsal view of a Holocentropus (Polycentropodidae) Caddisfly Larva from the Yakima River in Washington

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.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

Spring is FINALLY here!

OMG, there's something BLOOMING! (Coltsfoot, Tussilago farfara)

This looks more like an alien than a wildflower! (Skunk cabbage, Symplocarpus fetidus)

There were at least a dozen bass cruising this shoreline looking for something to eat...

Hey look, it's a real live Woolly Bugger! So THAT'S what they imitate!

The Au Sable is up! There will be some steelhead stuck in this little creek soon...

This may not be as spectacular as Spence's trip to visit the PA Chapter of Troutnut...but hey, I can WALK to this fishing spot from my home! It's been a loooooong c-c-c-ccoooooooold winter here in northern MI and spring has been a long time coming. Well, better late than never! I would have been happy with one fish today, but instead I caught SEVEN nice largemouth out of my favorite pond in Clark's Marsh. The biggest, in the photo, was 15.5", the others 12-14". Not really big bass but loads of fun on a 3-weight! No sunfish today, didn't see a single one out there. But there were a few early wildflowers coming up, and I saw the first butterfly (mourning cloak) and snake (common garter) of the year today too. And last night the frogs started calling behind my house!

I would love to have gone trout fishing today. However, there are flood warnings along the Rifle River and all of my other favorite spots are still closed until a week from this Saturday. Besides, pond fishing for sunfish and bass takes me back to my childhood and I always like to start my fly fishing season this way. And to think, two days ago there was SNOW in the woods and it looked like December...

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