Splash-Dunk Data For 2011 And 2012

Well, splash-dunking is just about over for this year – though there could be a few more splash-dunks if we get a nice couple days soon.  So far, though, the data for the last two years looks as follows:

In these last two years we've seen 265 splash-dunk events.  Each event consists of 1 to 8 separate splash-dunks, with an average number of splash-dunks per event of 2.31.  The case of 8 splash-dunks, seen just once this year, is an interesting case in its own right.  A later post titled "The Case Of The Constipated Darner" will tell that story in detail.  Here's the link:

The drop off in the number of splash-dunks in an event is roughly exponential, indicating that splash-dunks are approximately independent of one another.  Roughly speaking, each time a dragonfly dunks there is about a 67% chance it will splash-dunk again.

Most of the splash-dunks were performed by Happy-face Darners (Paddle-tailed Darner).  Here's one of them that was at Cranberry Lake just a few days ago:

A male Happy-face Darner (Paddle-tailed Darner) at Cranberry Lake recently.  What a treat to go to the lake and see these wonderful creatures.
