Not far from water, on vegetation. Second photo enhanced slightly as original was a little dark.
No interactions present.
I agree with the species ID, but this is an immature male rather than a female.
Yes, immature male. Female Blue-tailed Dams DO come in a variety of colours but a green thorax with a blue tail light is a young male.
Thanks both for pointing out it's an immature male. I've revised the id.
I'll look more closely next time.
