Confidence: I'm as sure as I can be.
Notes: White pseudo-pterostigman confirms this is a female but which species? The photograph that exhibits the damselfly with its wings open shows stripe on the dorsal midline of the last three abdominal segments. Diagnostic feature of Beautiful demoiselle is narrow brownish stripe that is darker than in the Banded demoiselle, which has paler, sandy-coloured stripe. Beautiful also has broader wings with brownish tint whereas Banded has narrower wings with greenish tint. Apologies for the poor quality of the photographs but much appreciated if anyone could confirm which species it is.
