A pile of Polistes wasps. Left photo is top view. See all 3 heads lined up like beads. Right photo is side view. That’s where you can see more clearly what is really happening. Crazy! Bottom wasp is smaller female. The pile moved around, climbing and flying. All the climbing and flying was done by the female with the males remaining on top of her. When I Googled it, someone said they’d seen a pile of 4 wasps. These photos are dedicated to my friend Tom Cullen to wish him a happy birthday!
