On The Fly: Mystery hatches can spark curiosity

I’ve always enjoyed the mental parts of fly fishing as much as the physical parts.

Watching insect hatches unfold around me in a trout river has fascinated me since I was a child. One of the most mysterious hatches I’ve ever fished occurs on the middle sections of the Frying Pan River during August and September. It’s infamously known as the toughest hatch and routinely confuses and frustrates even the best anglers; the serratella.

This unique mayfly has evolved over the years to become an asexual, flightless mayfly that carries an egg sack between its wings and is so tiny that about twenty of them could easily fit on the face of a dime. People come from across the country to fish in frustration trying to figure out and dial in this hatch. To my knowledge, no one ever has truly figured this hatch out. That’s kind of the beauty of it, in that we as fly fishers are always learning just like how the rivers are constantly evolving, shifting and moving.

Recently, there have been reports of a mysterious “super hatch” that takes in the evening hours along the Frying Pan River.

Generally during the evening hours, rusty spinner falls, caddis and green drake hatches, and occasional midge hatches, take place. None of these insects were the culprit of this new mystery hatch, however.

In an effort to fulfill my own curiosity, I fished the river on several occasions recently. It was an amazing learning experience. I saw firsthand how trout would key in on such a specific microscopic insect. I waded out into the river above where I saw the fish rising and collected some of the tiny insects that were swarming in cloud with a swoop of my ball cap. Tiny winged aphids, a terrestrial insect, were the culprit of the rhythmically feeding trout and the frustrated anglers.

I went home the next day, tied a bunch of size 30 aphid fly imitations at the vise and went back to the river the following day. The rest, as they say, is history, as many trout were caught.

Fly fishing is a constant learning process where we as anglers never truly know what the rivers, the fish and the insects have in store for us, always keeping us on our toes.
