While waiting for other birds coming in, I had these few pairs of Common Bluetail Damselflies to entertain me. I observed while they are coupling, other males came and harassed them. I even captured a video from a single male knocking the head of the coupling male (see attach few photos on them being harassed). If the couple is being too much disturbed, the partner will carry his mate along with him.
Attach a video is on one of the pairs mating.
All images are blurred due to the moving of water and strong wind blowing. This is just for a record only.
