I strangely enhanced the colors in this picture to highlight the silk thread from which this larva is dangling. It attached the line to the little tweezers I used to pick it up, and when I lowered it into my little photo tank it was suspended by the line for a while. I believe some authors have mentioned imitating this line when fishing Simuliidae imitations, but that seems kind of silly given the diameter involved, probably something like a 30X tippet.

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
