Here are 3 pictures of a stone fly I photographied on this screen at home (Sherbrooke, Quebec, near Vermont)...

This insect from the Plecoptera order is from the Perlidae family (pretty sure of that) but I have no idea about the species...

Can you help me to identify it???

Thank you again for your kind help!

Hello Konchu,

Thank you for your quick reply! It is really appreciated!

The length of the plecopteran is 3.3 cm or around 1.5 inch long from the head (without the antennas) to the end of the wings.

Any idea???

Someone mentionned Pteronarcys dorsata...

I'll have to verify this...

Ciao and thank you!

I believe it to be of family Perlidae (Golden Stones), specifically Paragnetina immarginata, which has the common name of Beautiful Stone.
