Plecoptera

Plecoptera
Quebec, Quebec, Canada
July 12, 2005
Size: Approx. 5 cm
What Plecoptera family is this? There were Perlidae in the river nearby, but I cannot tell the difference with adults from other Plecoptera families. What do I need to look at to differentiate adults? (Note this is an old photograph and I do not have better)
