It was a big priority for me on my last day in Hong Kong, to get more flight shots of the many Anax males flying at this pond.
The cool thing is that it turned out to be males of two different species. We have this one (Lessor Emperor) in Europe too, still no records from Denmark, but several from Sweden. In Europe it's considered to be the nominal subspecies, which has a brown thorax.
