      Thanks Tim. As you can see by the brevity, this is just a stub (as Wikipedia would say...). Because I was tweaking the Gomphids it seemed the best idea to get this up. I'll finish it and put in a photo shortly.

      You know that you can always use my pix... until you get your own, naturally.
      All my pix are Creative Commons / Credited, No Alterations, No Commercial Use...
      even if they aren't tagged as such... trying to re-tag past pix in Fumblr and the like is a pain as you cannot do so in bulk!!
