The
banded demoiselle (
Calopteryx splendens) is a species of
damselfly in the family
Calopterygidae. It is a
Eurasian species, occurring from the Atlantic coast eastwards to
Lake Baikal and northwestern China. Often found along slow-flowing streams and rivers, it is a common species throughout much of its range. This male banded demoiselle was photographed at
Farmoor in
Oxfordshire, England, near the
River Thames. Males have a dark wing patch that starts at the
nodus but can reach up to the wing tip in southern races.
