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.
