Broad-Bodied Chaser

Dragonfly, the broad-bodied chaser, Libellua depressa.  Male.
At the pond in Spring Park, resting on reed mace, 25 May 2011.

There were two of these large dragonflies patrolling the pond. They would not allow any sort of close approach until I was able to get near under the part cover of the clump of reed mace leaves this one was perched on.

The small pond is shown below. The reed mace is on the left. It is choked with mare's-tail, Hippuris vulgaris, which was introduced by accident.
