Swamp Darner dragonfly (female, oviposition)

The following photos show a Swamp Darner dragonfly (Epiaeschna heros) spotted on 23 May 2014 near a vernal pool in a relatively remote location in the forest at Huntley Meadows Park. This individual is a female, shown laying eggs (oviposition) in a muddy drainage ditch.

All female damselflies and many female dragonflies, especially Aeschnidae, have an ovipositor that is used to puncture aquatic plants, logs, wet mud, etc.; eggs are placed singly in the puncture. The ovipositor is clearly visible in all of the following photos.
