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.

Hi everyone I am from Connecticut and I fish the Farmington River most of my time. It seems to me that some years the hendickson hatch is heavier than others. What would be the greatest determining factors regarding next years hatch of any mayfly? Some dicussion wants to blame it on high water during a current years hatch but I feel it has to be more complex than that like what if we got a cold frost one night before the spinners have a chance to mate and drop? All answers will be appreciated.

Good luck!
Of course the other question is will the hatch be late or early?
Good luck with that one too.
