Moved from ID Request.

You got me going with the third photo.

First I assumed them all the same individual and thought - oops, it's a male in female clothes (the slender form did bother me from the start - didn't "look" female), and thought I'd goofed only the gender. Then I looked more closely. They aren't the same species. Then I looked more closely yet at the first two photos and realized "boy did I goof". I jumped too fast to my conclusion, and didn't pay close enough attention to details of morphology the first time 'round (just the coloring). I suppose I shouldn't do this when I'm sleepy. Sorry about that.

The third photo is actually a male Trachyrhachys kiowa - there seem to be lots of those in Texas this year. It does look a lot like the other one though.

The first and second photos I didn't even have in the right subfamily. That fellow (yes - I'm going with male) is Encoptolophus costalis.

Oh, and this is fun for me (even if occasionally I get a tiny bit embarrassed and red-faced - especially after your kind comment, when I actually had goofed - thanks by the way). I love looking at these pictures and seeing what is where, seeing the variation, and I really enjoy the challenge of identifying them (some are very challenging too).
