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.

I realize this is well worn topic on the forum, but I just got through posting a comment stating that I had Hexagenia limbata alongside Anthopotamus distinctus here in Southwest Virginia. After posting it I second guessed... and in reading the discussions on the forum about this there seems to be some hent that a broad geographical division line can be drawn between Hexagenia rigida and Hexagenia limbata with limbata being more common in the northern midwest and rigida being more common in east/southeast with a ton of overlap. So my question is: if this is true and would being in SW Virginia (near NC) increase the likely hood of one over the other?

I'll post a photo of the specimen shortly,

Aaron-

Will be interested to see your photo. However, unless it clearly shows the penes of a male imago, attempting to differentiate between Hexagenia limbata and H. rigida would be highly speculative, at least in my opinion.

Next year I'm photographing the penes! Perhaps it is better to attempt to resolve it after that - in the meantime I'll just refer to them as the Hexes of late June.

Aaron...Don't say that too loudly, your neighbors will be putting you on the list...:)

That is a wonderful photo, by-the-way...Somewhere on here I have some pictures of her cousin, step-child maybe more correct since she's been moved from the genus...Still hasn't been totally kicked out of the family yet, but who knows...Litobrancha recurvata.
