If you collect the some of these creatures , it will surprise you how thin the
body of the nymph is. I find that hard to duplicate with Chenille, and prefer
to dub the body very thin with something like wool or superfine dubbing for the
abdoman using just enough to slightly change the color of the thread. I like to
tie them on swimming nymph hooks and use either bead chain painted black or a
pair of black plastic beads that I find in sewing shops for the eyes of the
ones that I want to run very shallow. I use olive Squirrel dubbing in a loop
for the thorax and partridge for the legs.

Hi Big Dale,

Your tying is excellent BD, but although the insect is thin, we so ften
tie imitations that are bigger than the naturals. An example is the
midge pupa - the buzzer. Tied on a # 14 sedge hook it is enormous
compared to a natural, but the fish love them.

In my brief description of the tying, I forgot to mention the thorax.
This I usually tie with a slightly darker dubbed olive dubbing material
with a "wing" case of pheasant tail tied over and dividing the brown
partridge hackle. As for eyes, I don't usually bother, but on occasions
when I want a fly that will sink well, I tie in a gold head bead which
is then placed beneath the pheasant tail wing case. black eyes can be
painted on the bead if needed.

The trout aren't really fussy as long as it roughly represents the
natural.
Of course a well tied imitative pattern is a joy to behold :-)
