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.

This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.

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.

Fished the late / light Hendricksons below Mio (Au Sable) last year and was left with the impression that the daily schedule is a little different there. What I mean specifically is that we arrived at the river around 11am to an already in progress spinner fall getting started, then wind slowed things down and we had great hatchers most of the rest of the day hoping for spinners to re-appear. All this commenced on an a-typical schedule. Typically up in the Holy Waters and the South one expects to find hatchers at the peak water temp which is about 2-4 pm that time of year.

I suppose the all early / all day hatching can be explained by the warmer temps spilling over from Mio Pond.

I'd love to hear the low down on what the expected daily hatch schedule is down there (for Hennys). It seems a little a-typical but this is based on three data points.
