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.

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.

We had a warm up over the weekend here in northern Michigan so I got out of the house and fished a local stream. Stumbled across this caddis adult and was wondering if anyone had any clue as to what it might be. Body length from head to the rear wingtip is 11mm. It was the only one I saw, walking around on the snow right at the water's edge. Any ideas? Thanks!

Alex-

My guess would be Frenesia missa, but Dave will know for sure.

Yup - nice pics - I think it is Frenesia - pretty dark and a little small. You cannot determine species without looking at its private parts At that size and location I was hoping for something like Chilostigma - so far found during winter in a few very small spring habitats exposed in winter because they are warm enough to melt the snow above. Chilostigma should be also wandering on the snow around the spring opening. Not much else known about them and who knows what you might find really unusual in the winter because no one really collects then. Did you keep it?

Yeah, it died last night, but I've still got it sitting on my fly tying bench under a vial.

If ya send it to me I will put a species on it. It's a female but I should be able to separate them cuz it looks in good condition. We will see how good Roger did with his key by geography :-) He is probably right on this one because there are alot of reported records for this genus and, so far, missa is the only one reported this far west. I will send address by PM. If it is dry, just put in tissue and into small vial. Then in something to mail so vial does not get crushed. Parts may come off a dry specimen but should still be able to identify.

That makes me eager for the good bugs to come. It won't be long.

Daytripper - your critter arrived in fine shape and is a female Frenesia missa. Roger rules!

Dave-

That's kind of you to say, but "you da man".

Incidentally, apart from my belief that Frenesia difficilis has yet to be identified in MI, my belief was also that the reported length (11 mm.) was too short for F. difficilis, and just right for F. missa.

I love this place, thanks to all for your help identifying this one. As far as northern MI fly fishing hatch charts are concerned, this bug doesn't exist. Kind of cool to know these are possibly out there in the winter.

WTG Roger, and Dave.

DT, as far as the trout are concerned, it may not exist either, due to time of year, habitat, and habits. But ... there may be places and times. Look up Frenesia and see what is said about them. It can pay to know what to be looking for.

Hi Alex-

Caddisflies by Gary LaFontaine has a comprehensive writeup on genus Frenesia, in which Gary indicates "they survive into the winter and are commonly seen on snowdrifts even in January."

True, but there is always hope...

I'll have to pull Caddisflies back off the shelf.

People ask me what I do in winter when there's no baseball. I'll tell you what I do. I stare out the window and wait for spring.
-Rogers Hornsby

I think this puts it into perspective for flyfishermen as well as ball players...
All men who fish may in turn be divided into two parts: those who fish for trout and those who don't. Trout fishermen are a race apart: they are a dedicated crew- indolent, improvident, and quietly mad.

Antonio, I agree with Rogers, but I couldn't wait for Spring. I fished Bobs Creek today for about 90 minutes in a blizzard and 13 degrees. I need to catch a trout for January and time is running out. Well, the creek was nearly frozen shut except for a small trough down the middle. My entire leader turned into an ice rope and I couldn't tell if I had a take or not. I guess I don't really need to tell you I caught no fish. It was a pretty scene though.
