Austroagrion watsoni is widespread in Australia, just missing from the far western edge, and also occurs in New Caledonia. With a vernacular name featuring “Billabongfly”, where else could it be?
We found our first example on a visit to the dam in Stanley, near Beechworth, Victoria; it was the immature male without its colour developed and it took me a while to realize what it was. I have subsequently seen mature males on my 2019 trip to Queensland, though I initially mixed them up with Pseudagrion microcephalum (Blue Riverdamsel)
