Thanks for that excellent report! We stayed at Catcha Gardens for a week last January and visited Ivans quite a lot during our time there. Snorkeled all along the cliffs from LTU Past Catcha. Love that area up there. (We usually stay at Blue Cave Castle and did 2 weeks there also.)
Dragonflies? We had a swarm come through our backyard garden last year. I was just before a hard rain, maybe that stirred them up.....
Here's the video.
