Your letter to the bugman:  Saw this a few weeks ago in San Jose Costa Rica in the late afternoon. Note the barb. What is this?
How you want your letter signed:  Jim R


Dear Jim,
This is a Katydid in the family Tettigoniidae, and what you have described as a “barb” is actually an ovipositor, an organ adapted to function during the egg laying process, indicating that this is a female.  We do not recognize the species.
