Lawdog & My Fellow Bee Hunter,
In my neck of the woods we hunt the large bull and sometimes "rogue" grasshoppers too. As to the bumblebees mostly leave them to pollenate. However, when camping in mountains one of the favorite targets around camp are the yellow jackets. Not so sure that the Red Rider is "enough gun" especially when attired in, as you describe, "The proper clothing to wear is a pair of gym shorts. Just more sporting that way. Got to be fair now." Sometimes there is "fair" and then there is "stupid"!
I like to shoot the yellow jackets over bait; some bloody hamburger works well as does a freshly killed bull grasshopper. With the Webley Hawk .117 I place the bait about 15 yards from my hide as it has a Williams reciever sight on it and that is just about "minute of yelow jacket" range with it. With the R9 .20 cal I usually place the bait a little farther out from the hide. Of course the "hide" is a folding camp chair, with arm rests of course, strategicly located in the shade with a ready supply of "cool ones" within arms reach. Life can be good!
