Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.

Jason,
I sent you an email about this yesterday-- I don't know if it went through so I thought I would post it on the board for everyone.

This week I collected insects for my bug aquarium taht I set up each spring. The day after, I was looking over all the bugs in the tank, and what do you know, I found another Neoephemera! The good news is it is a nymph and it is alive and well in the tank. Hopefully it will survive and I can get some photos of the adult. I did not want to remove it from the tank, but I did get a photo of the nymph from the outside.

Are there some features I should be looking for to possibly identify the species?

Caleb,

You have two species of Neoephemera in North Carolina, N. purpurea and N. youngi. They are easily differentiated by mature body length. N. purpurea achieves a length of ~16mm, whereas the smaller N. youngi achieves a length of only ~10mm.

Caleb,

Thanks for the picture! Very cool. I hope you have luck hatching it out... I'd like to see the adult!
