Male WhiteTail Dragonfly (Plathemis lydia)
(Identification courtesy of my son Sam, full-time med student, part-time Herpetologist and naturalist)

A different species from the first (and if anyone knows the genus/species, please email me). One minor feature of this shot which appeals to me is an essentially unnoticed ripple effect in the water, on the lower left. Canon 100-400 at 400 mm, ISO 100, f/5.6, 1/200 second (hand-held).
