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.

I was not fishing, but happened to be at an unrelated social event on a hill above this tiny creek (which I never even saw) when this stonefly flew by me. I assume it came from there. Some key characteristics are tricky to follow, but process of elimination ultimately led me to Sweltsa borealis. It is reassuringly similar to this specimen posted by Bob Newell years ago. It is also so strikingly similar to this nymph from the same river system that I'm comfortable identifying that nymph from this adult. I was especially pleased with the closeup photo of four mites parasitizing this one.
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.

Guys;

Haven't been able to get out even once yet in the Catskills! just wondering if anyones been out here yet and what they're seeing on the water. Couple of guys have told me they're seeing predominantly midges,black stones and some small olives but beyond that, havent heard anything else yet. Any Hendricksons been spotted?

We're still pretty frozen up here in northern lower MI. Steelheaders are out in force but there aren't even many fish in yet. Even small bodies of standing water still have ice cover! Walking along the lower Au Sable all I've seen is a few random midges. I haven't even been near a trout stream since October, but I would guess we're a good while before Hennie season. Which perhaps is good, maybe they'll be in full swing once our opener is here on the 27th...

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

SW Lower Michigan: I got out for the first time last Friday, upper Rogue and near-perfect conditions considering the time of year- air temp 56* by 3 pm, partly cloudy, water level steady and clear @ 45*. Little Black Stoneflies (sz 16's) were falling and we had some really good fishing.

Sunday we waited until 4:00 pm when partial sun was forecast, zilch on any insects other than some scattered midges(?) we guessed a sz 22 or so, grey with an orange/red egg-sac on their butts.
We've got heavy rain for the next 4 days, 80-100% every day and 2+ inches by the time it ends. I'll be tying more BWO's and Sulphurs in the meantime.

Mack, things have thawed out a bit more in the last day or so, and we're geting a nice steady rain right now too. Oscoda does stay a bit colder than the surrounding areas - our flowers are a bit later in spring here than further inland. Look it up on Google Maps!

P.S. Hopefully I'll have a hatch report from the Rifle River within a couple of weeks...
