The Iris Caddis for the Grannom Hatches

In the last post we wrote about fishing an olive bodied Iris caddis to imitate the emerging Grannoms (Brachycentrus sp.) that are so common on Eastern waters this time of the year.  This year a few weeks earlier than what might be considered normal.    Here's a couple of shots of that fly as I tie them - above a side view, and below what we might call a fishes eye view.  I tie them on size 14, 16 and 18 dry fly hooks, as their are several species of this caddis that hatch and size is crucial to success. 

We should see good hatches of Grannoms right through mid May, with egg-laying at dusk occurring right through the end of May - caddis can live 2-3 weeks after hatching and wait until conditions are ideal to mate and lay their eggs.

Tie some up and give them a shot anytime you see grannoms about.

Sharpen your hooks.

Such a deadly pattern in my home state of MT. Truly a "don't leave home without it" fly. Mostly used in sz 16. In Tan, olive and Gray. Great content by the way. I've only recently discovered your work here. Busily consuming it. A great resource.
