The Delektable Bug by Dan Delekta of Beartooth Fly Fishing is a large, aggressive stonefly nymph pattern with “a lot going on.” This version has the chenille body and abundant legs of a Pat’s Rubber Legs (aka Girdle Bug aka Turd), but also a marabou tail and a collar hackle. It has risen to become my best or second-best style of stonefly nymph over the past couple seasons, now certainly eclipsing the basic Pat’s. This variant is tied on a jig hook and has a couple small material additions in an experiment to cross over to appealing to fish who like my OTHER favorite stonefly lately, the Bomb Series nymphs, in this case the brown Stone Bomb. Otherwise it’s identical except in color to the basic Bug.
The basic Bug is the least-complicated version of a whole family of Delektable stonefly nymphs including the Braided Stone, the Hurless, the Mega Prince, the Mr. Rubber Legs, and the Stoner. Most are available in standard or flashback variants. These other variants add, subtract, or change a few materials, but otherwise use a similar tying process. For example the Mega Prince has a peacock herl body instead of chenille and adds biot wings, while the Hurless simply has a body of ostrich herl.
In most respects I use “Delektables” of one breed or another in the same situations where I would use other rubberleg stoneflies. I find the chenille-bodied version given here generally more effective when the water is high and/or off-color, as well as for ornery fall-run brown trout, while during the summer when the water is lower and clearer I prefer the similar Mega Prince or Mr. Rubberlegs.

Note that I have no business relationship with Delektable or Beartooth. I just use some of the flies.
NOTE ON FISHING DATES MENTIONED IN THIS VIDEO: The streamflow predictions for the Boulder have changed and it is now forecast to remain above 2000cfs through at least June 17, alas. I now expect it to drop into shape around June 20, 2020.
