The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.
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 Tim,

Parachute style dry flies were originated by William Avery Brush of Detroit circa 1930. See http://www.flyanglersonline.com/features/oldflies/oldflies20090622.php.
Best regards,

Thanks. My friend and keeper of the flame for AuSable (MI) original patterns always told me they were originally called gyros. Appears as though he was right. Michigan has become, over the years, a big producer of parachute flies. Earl Madsen's "Hatching Caddis", a giant parachute tied to ape an emerging Hexagenia (they were erroneously referred to as caddis back in the day) was perhaps the first parachute from this area. It was the forerunner of Clarece Roberts well know Roberts Drake.Earl's fly dates to the late 30's I believe.

My great grandfather is William Avery Brush. I'm actually holding his patent for this from 1934 in my hand. Just ran into it while cleaning out some of my parents things. Knew of course about the Brush Runabout and his auto ventures but wasn't aware of this area of endeavors.
