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.

The "Fountain Flats" stretch of the Firehole was fishable in the morning after an uncharacteristically cold August night.

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.

So I have been fly fishing for just about 3 weeks now, have got my cast pretty good on my floating line and dry fly, but in a few weeks I will be gearing up to go to a bigger lake and want to either get sink tip line or sinking line, what should I get as a absolute noobie, and what are some do and don't, should I use a strike indicator or just go off feel, I have some wet flies and figured I would try some casts and holly. It was all over the place, is there any tricks to help with this. Any help at all would be much appreciated, thanks
