Hex Mayflies
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.

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.

I have fished a couple of different stretches of the Esopus this year.Could you tell me what stretch of the creek these pictures are from?The clarity of the water tells me it is somewhere above the Shandaken tunnel.

These pictures are from way up in the headwaters near Slide Mountain.

Thanks for the quick reply.I was actually on this stretch this summer,but the water was so much lower,much too low,in fact.I ended up going to a spot on the other side of Rt 28 above Big Indian.Water was low,but fishable there.Got 2 small brookies,so I will go back,next week as a matter of fact.I will explore that area around and above Oliveria next spring.Fished another tributary stream a couple weeks ago,Woodland Valley Creek,down stream of here,just above Phoenecia.Small stream,should be nice in the spring.
