fourx, I have seen b.w.o.s and this was similar but different in that the thorax was much thiner and darker and the legs similar to a water bug. When I first saw them coming off I thought the same but when I caught one, I didn't think so. I don't carry a camera and have drowned my cel phone twice this summer so taking a pic with it was not possible.
I saw a pic last week on the message board but cannot find it. thanks for offering, you maybe correct.
