Walking along the shore near the pond on an overcast hot day, I noticed a dragonfly perched on a stem of Horsetail.
This is a Halloween Pennant Celithemis eponina dragonfly. They usually perch horizontally like this, waving in the breeze pennant-style, at the top of vegetation.
At 1-1/2 inches long, this dragonfly would be a juicy meal for a predator.
