Scud has been made from a mix of different dubbings, first of all it was the Polar Dub (Hareline brand), which has an interesting structure i.e. is slightly transparent when wet and bit of a great scud's dubbing - the Sow Scud (Wapsi brand).
The second dubbing has something what you can see on the penultimate picture and the difference is visible only at an additional UV light.
Back of the scud nymph has covered with severals layers of thin UV glue and the final result is the most real.
