Found in garden pond. About 40mm long. I don't think you can get to species level from this photograph (I certainly can't!!).
No interactions present.
If it was from a garden pond it's most likely but not definitely a Southern Hawker. They are regular visitors to these small water bodies, more so than the other hawker species.

Thanks Chris - I do get Southern Hawkers laying eggs in the pond.
Phil, on the balance of probabilities I think we have a reasonable answer then. Chris
