Common Stonefly Naiad

What kind of stonefly is this? He’s about an inch and a half. I caught him in february in central pennsylvania. I put him in rubbing alchohol for long term studying and he didn’t die untill the next day. Thats one tough stone. Please email me back when you get a chance. Aquatic insects are fantastic!!!
