Stonefly - Paragnetina immarginata

Stonefly - Paragnetina immarginata
Groton, Middlesex County, Massachusetts, USA
July 19, 2009
Size: 31mm
This stonefly was inside my house, and I suspect it emerged from one of several larvae I put in the fish tank.

Moved from Paragnetina.

Paragnetina immarginata
Roger was correct.

Thanks Roger
I saved the specimen and will be giving it to Don Chandler at UNH. Hopefully the species identification will be nailed down.


I believe it is Paragnetina, probably P. immarginata.
