Hey: I've got Dulude's book. What is it you were wanting to know at this point? I don't read or speak much French, so I hope nothing is lost in translation.

Ha! Great. Trying to run down any research reporting on the presence of atrocaudatus in QC. According to Michel, the author mentions its presence, and there's hope that the reference for this is in the biblio.

Thanks

He had it listed as being in QC, but I didn't see anything to substantiate it being there. In other words, he could have expected it but not seen it yet (though I have little doubt he saw something he thought was H. atrocaudata). Curiously, I don't think he had it listed in his hatch chart.

Thanks Luke,

I believe the author is an angler not a scientist which was why I hoped he cited a paper in the biblio. Though he's got the number of species right, I wonder if he's confusing atrocaudata with bilineata, the third species that has been found there.

Still, I have to agree with Jason that this sure looks like atrocaudata (whatever that means). :)

Hello all,

I finally succeeded to open the door of my shed :)

So I got finally the measure and know now how long it was...

Once again, I am really surprised about the results: this Hexagenia measures 1.9 cm only!!!! Wow! I was sure it was at least 40mm!!! So I realized that the big wings, the fact that he often have its front legs in front of his head and the long cerci make him looks very bigger (what an illusion)! (Imagine if it was a trout! ;-) ).

So knowing now its size, can we say for sure that it is Hexagenia atrocaudata? It seems so, isn't it?

Thanks,,

Michel

I'm glad you got the measurement! Those Hex mayflies do tend to look much bigger than they are.

I certainly think atrocaudata is looking pretty good as an ID now.

I agree. Thanks for following up on the measurement, Michel.

So Michel, does this mean that mean I have your blessing to move it back to H. atrocaudata in BugGuide?
