Your letter to the bugman:  Hi,
We have found TWO of these bugs in our home in the last 12 hours. We live in a small city, but our house is at the end of a street adjacent to farm fields. Given the amount of rain we have had this spring, there is standing water in some areas of the fields not far from our house. I have never seen any of these bugs before that I know of, but especially not in our house. Last night’s sighting including the bug crawling up from the inside of a new reclining chair!
How you want your letter signed:  K

Midwestern Salmonfly

Dear K,
This is a Giant Stonefly or Salmonfly in the genus
Pteronarcys.  Based on your location, we are surmising this is a Midwestern Salmonfly, Pteronarcys pictetii, which is pictured on BugGuide.
