hi there. I live in Labrador Canada and every summer we get this bug and no one knows what they are. I was hoping you could help identify it.
Thanks

Giant Stonefly

Dear n/a,
This is a Giant Stonefly in the genus Pteronarcys and you can compare your individual to this photo from BugGuide.  Stoneflies have aquatic nymphs or naiads, so they are generally found near a source of water.  Having a healthy Stonefly population is an indication that the nearby water is relative pure and pollution free as they cannot tolerate contaminated water.
