I’m wondering if this dragonfly may be the same species as that at sighting 4670131. A very slim dragonfly, all black except for an off-white line along the upper edges of the thorax which almost form a ‘V’, and very thin bands, of a similar colour, around the abdomen; the 3 at the very back end being slightly thicker and closer together, and have a distinct bluish tinge. Some very small off-white marks appear at the rear end of the thorax where it joins the abdomen. The black eyes feel to be particularly protrusive. The wing veins are black and all wings have a black dot on their front edge towards their outermost ends. Possibly a Common Flatwing (Austroargiolestes icteromelas)?
