Odd Spokane Resident
While tilling a flower bed this last summer (May/June), my wife found this bug under a top covering of pine needles. I have never seen anything like this.
It has a beautiful black with orange outlines. Its wings are huge!

Giant Stonefly
Hi Spencer,
This is a Giant Stonefly in the family Pteronarcyidae. According to information posted to BugGuide, we believe this is probably a California Salmonfly, Pteronarcys californica . BugGuide indicates: “The California Salmonfly ( Pteronarcys californica ) is common in western United States and southwestern Canada; it is an important food of trout and salmon, and a favorite bait of anglers.” These aquatic insects are often attracted to lights.
