Salmonflies
Pteronarcys californica

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

For how many years, I wonder, have these huge slabs of rock sheltered wild brook trout?

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 collected these insects from the head waters of a spring creek just south-west of rochester, ny. In this stream i don't believe the mayfly nymphs play a significant role in a trouts diet until they hatch, as they are out numbered 500-1 by scuds on the stream bed and only become distinguishable to trout on their way up to the surface or while in the surface film.

Sorry for the crude macro photos ... I'm still trying to prefect this part of my game...

this is what i have so far...

1 Are #1 & #2 the same species? Family Ephemerellidae ... subvaria?
2 Family Ephemerellidae... subvaria? or Fam. Caenis?
3 Family Baetidae ... but what genera? Pseudocloeon?

Andrew,

I believe your photo labeled #3 to be of a Baetis nymph, probably B. tricaudatus, and your photos labeled 2 & 1 to be of Ephemerella nymphs, both probably E. subvaria.
