Redd,
They are about 2" long, but you can tie them pretty much any length you want.
The tails are medium vernille with the tips burnt. The body is flat holographic tinsel with blood red midge tubing wrapped over the tinsel. The beads are 5/32. I usually use 1/8" or 7/64" but I was out of them.
Here is a little different version with smaller bead and a silver wire rib to give the abdomen segmentation similar to a chironomid pupa body.
Hope this helps,
SF
