A Halloween Pennant Dragonfly

I harassed this dragonfly for a while this morning; I hoped it would perch on something else than a dead leaf or muddy stick; I suggested the blue pickerel week, but in the end we compromised with something green. I wonder if one of you buggers entomologists out there could ID him for me.
Thanks to Dodge for identifying him: a 'Brown-spotted Yellow-wing Dragonfly' also know as a Halloween Pennant.
