Xiphiagrion cyanomelas

Does Odonata stand on water? The answer from AI Overview says no. However, I had an overwhelming observation on Xiphiagrion cyanomelas at Paya Maga (ca. 1650 m a.s.l.), Sarawak in 2010. I spotted many males of Xiphiagrion cyanomelas standing on water at water pools or small ponds in Paya Maga. Their legs were basically on the water, and sometime with their tail end was also touching the surface of water. When wind blew across the water pools, they drifted smoothly across the water surface.
