Out hiking/geocaching in the hot, hot sun with my camera, on the trail near South Run Park.

A number of sources indicate that for some species, female dragonflies dip their abdomens in water to deposit eggs after they’ve been fertilized; there was a bit of that going on in the stream, along with a bit of tandem flying, if you take my meaning. Not sure if the collision is territorial, a clumsy mating ritual or just Odonata dickishness.
