What’s this bug? Can’t tell from the picture, but it has 3 white lines on it’s wings. The picture was taken, 1/9/14 which is winter for us in the Pacific Northwest.
This is a Northern Caddisfly or Snow Sedge. Caddisflies are often mistaken for moths, and according to BugGuide: “Adults resemble moths, but wings are hairy instead of scaly.” Caddisflies also share some behavioral characteristics with moths. According to BugGuide: “flight activity begins at dusk. Adults are attracted – sometimes in great numbers – to artificial light.” Larvae, which are commonly called Caseworms, are aquatic, and of the habitat, BugGuide notes: “Species most diverse in well-aerated streams, but also occur in lakes, ponds, and marshes.”
Thank you so much, Daniel Marlos!!
