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.

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.

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.

Can anyone please help me identify this nymph? I noticed this as I was zooming in on the maccafertium nymph. Found in North Jersey (Big Flatbrook) last month. Thanks!

I'd suggest putting nymph on a white background and taking a larger photograph for identification. Our bug guys are good, but they may not be able to make out enough detail on the one posted here. A big white plastic cap from a cat litter jug would make a good background, or any lid with a white inside. Adding a little water might make the legs, tails, etc. stand out more.
