Yellow Tailed Ashy Skimmer

nived,thanks so much for your valuable feedback. You are a great teacher!!

Hi. Hemma. Let me start by saying that it's a very unclear picture, probably because of less light (sunset?), and considering the brown of the branch is appearing as gray (white balance problem), I think this is a Potamarcha congener (female). The faintly seen colored streaks on the thorax and the ovipositor flaps hint this being a female of this species.

Here (http://www.projectnoah.org/spottings/127...) is a clearer picture of a similar specimen. Cheers!

granite ghost?
