These are always abundant in my stream samples and have even found them wriggling around on my pack after a dunking.. I have always thought they were midge larvae as that is the common assumption I've gathered from local anglers, but due to their size and shape I started to question this. Scouring online resources and comparing photos led me here, where I see they are a different critter altogether. I have never heard of anglers discussing the use of Simuliidae patterns but I'm looking forward to experimenting with them in the future. Thank you for the photos and the resource! -Mike in KY
