Pentagenia vittigera
Mark-
Lloyd Gonzales identifies your bedroom visitor as a

Stenonema femoratum

I know better, but I often fall prey to the convenience of leafing through the guide and placing things where they look like they belong. In this case it seemed like >99% of the very large mayflies with this general appearance were
S. femoratum
, and I figured that something randomly showing up in my bedroom in the middle of a city was probably not going to be anything uncommon. Thanks for following up on it for me, I'm excited to have found something unusual.
That being said, I've had a good run of finding unusual things in my little house! The key is to have lots of holes so the insects can get inside! :)
