Hexagenia limbata

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.

Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva

Dorsal view of a Glossosoma (Glossosomatidae) (Little Brown Short-horned Sedge) Caddisfly Larva from the Yakima River in Washington

I caught this tiny larva without a case, but it seems to key pretty clearly to to Glossosomatidae. From there, the lack of sclerites on the mesonotum points to either Glossosoma or Anagapetus. Although it's difficult to see in a 2D image from the microscope, it's pretty clear in the live 3D view that the pronotum is only excised about 1/3 of its length to accommodate the forecoxa, not 2/3, which points to Glossosoma at Couplet 5 of the Key to Genera of Glossosomatidae Larvae.

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.

Does anyone remember seeing a popular article about the Rev. AE Eaton and his influence on Frederic M Halford from a few years ago? I am trying to track one down, but I don't know where it may have occurred. I'm hoping the author might even been lurking here. If so, send me a PM, please. Thanks for any help from anyone! McCafferty did one about Eaton and some others, but this is different from that one.

Hi Luke,

I don't know of any article in a fly fishing periodical, but Ernest Schwiebert in his Nymphs II writes a fair amount on their relationship as well as Eaton's other contributions as the "foremost ephemeropterist of the latter 19th century".

Regards,

Kurt

was able to track down the author - the article isn't quite done yet. I'd assumed it had been published already, but it still is being worked on. Thanks for the help anyway, Kurt.

Hi Luke,

As little as it was, your welcome. Glad to hear you ran it down. Please post a follow-up when it's finally done.

BTW - I could be wrong, but I think I remember reading somewhere that Eaton was behind Halford's spur formulae for trichopterans as well.

Regards,

Kurt
