Limnephilidae (Giant Sedges) Caddisfly Larva Limnephilidae (Giant Sedges) Caddisfly Larva

Dorsal view of a Limnephilidae (Giant Sedges) Caddisfly Larva from the Yakima River in Washington

Hi Jason,
I am putting together a news video on black flies in upstate New York. Looking for some stock images, could I possibly use your image for the video?

Thanks!
