Banded damoiselle - closeup, Heeswijk-Dinther, Netherlands
This is the male, in its typical competitive pose where it aims to chase away other males. When challenged, a fake fight ensues in mid-air, where they display the inside of their wings, supposedly an impressive feat.
From this angle, you can just about see the white tip at the underside of the end of the abdomen. This white tip is flashed to the female before a courtship chase starts.
