Female common darter dragonfly ovipositing (depositing eggs) in the less than salubrious looking water of Compton Park pool earlier today. There were two or three males around, spending most of their time either resting on the decking or in brief bouts of jousting with each other.
There was also a male southern chaser patrolling over the water as its territory, though it never came close enough for me to grab a picture.
