This uses the stick figure I sketched some time ago. It's based on the Happy-face Darner, also known as the Paddle-tailed Darner, and is taken from a photo, ensuring that all the proportions are correct.

The Vitruvian Dragonfly
We're all familiar with da Vinci's Vitruvian Man, which explores the proportions of the human figure. Inspired by it, I decided to put together a version for dragonflies. Here it is, the Vitruvian Dragonfly:

Splash-Dunk Events For 2013
Well, the dragonfly season for 2013 is drawing to a close. We're still hoping to see an Autumn Meadowhawk one day, if the Sun comes out, but the darners are long gone, and with them the splash-dunks and spin-drys.
It's time, then, to collect the data for this year. Below is a chart showing the number of splash-dunk events seen this year as a function of the date of observation.
Notice the roughly "normal" distribution about the peak centered at September. I knew September was a good month for splash-dunking, but hadn't realized how much it stands out from the other months.
Most of the splash-dunk events were observed at Cranberry Lake, and most involved darners, like the Happy-face Darner (aka the Paddle-tailed Darner) depicted to the right. This is a "stick figure" I produced from a photo of a Happy-face – so the proportions are correct. I plan to use this image to illustrate "wing grabbing" when attaching in tandem, as well as other behaviors.
