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

Ephemerella subvaria (Hendrickson) Mayfly Nymph Pictures

Here's another nymph with the strange brownish coloring rather than the olive I usually see for subvaria. I suspect it's the same species and it's just wide individual variation.

This mayfly was collected from unknown in Wisconsin on February 7th, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.

are the male and female E.subvaria nymphs identicle, or like the duns, different?
