This summer we opened the pool.  However, we had a series of issues including several bouts of sickness and a lot of rainfall.  It just got away from us and it wasn’t worth the added expense to get it back up and going again this season. 

A couple of weeks ago I noticed some tadpoles in the pool.  Nothing unusual, except that the tadpoles were rapidly disappearing – too quickly for them all to be changing into frogs.  And then over the last several days I had noticed some “insect shells.”  It was obvious that whatever it was had gone through some type of a metamorphosis and broken out of these old bodies.  I suspected dragonflies.  I had assumed that their eggs were laid in water, but I never knew exactly what a “baby dragonfly” looked like. 

After some more observation and some research I found out that these creatures were indeed dragonflies [nymphs].  This explained the disappearance of the tadpoles, as apparently dragonfly nymphs have quite a taste for them, and these shells that I had found were called exuvia, which is the skin that the nymph had left behind.  I watched one of these nymphs making its way out of the water last night, and this morning found this little guy all busted out and preparing for take-off.  How exciting!
