Your letter to the bugman:  This insect showed up on my deck on June 12, 2012, in the tall grass-aspen parkland eco-region. I wish I had more info. None of my searches have come up with anything close.
I sure hope you can help solve this mystery!

Salmonfly

Dear Laura,
Giant Stoneflies in the genus 
Pteronarcys are frequently called Salmonflies.  Despite there being no reports from Manitoba listed on BugGuide, since the surrounding provinces have reports, we would deduce that the range of the Giant Stoneflies also includes Manitoba.

Thank-you so much, Daniel! I’ll be looking up more info on the salmonfly now
Laura
Very cool. The Roseau River is only a 1/2 mile away and it has a rocky bottom, so that’s where it came from. I’ll be looking for larvae when the water’s low enough.

Thanks so much for opening another window to the local ecology!
Laura
