Ira Lingren developed some buggy-looking, easy-to-tie nymphs that catch fish; can't ask for more than that. Here's the olive version; change colors to suit your needs.
hook - Mustad 3906B #14
thread - Danville 6/0 black
rib - wire x-small gold
tail - black hackle fibers
abdomen - marabou olive
thorax -peacock herl
hackle - hen black
Part 1
mash barb and attach thread and wire; keep tag end of wire on far side of hook while wrapping thread to point above hook barb
measure some hen hackle barbs (hook gap past the bend) and tie in
tie in some marabou fibers (keep it sparse) and wrap body up to 60% mark
tie in some peacock; twist together and wrap thorax
counterwrap ribbing through body; helicopter and tie off
