Dragons and damsels, Green Lake

I came by Green Lake about 4 p.m. on a warm, sunny afternoon, and found myself quickly distracted by dragonflies.
Pachydiplax longipennis (Blue Dasher)

Libellula forensis (Eight-spotted Skimmer). This was the hardest to photograph. They seldom stopped, and when they did, they chose perches close by the water. They were amazingly active, jousting with each other in the air and swooping down to touch the water.

Ischnura erratica (Swift Forktail), which like all damselflies has a very athletic way of mating. The male grabs the female behind the head using special claspers. They fly around. Then the female bends her abdomen forward to get his sperm, which he is storing in a special compartment in his thorax.
