Dragon Flies

Ray went for a long bike ride and to visit a friend this morning, I had a sit by the pond and watched young Dragon Flies drying their wings and getting ready for the off. I managed to collect some of the empty larvae cases that they had emerged from. I will keep them to show children that visit.
By the time I went out this afternoon they had all flown.
Wonder if they all "hatch" on same day or might I see more tomorrow.
