Interesting coloured critters during the weekend

Biked to school yesterday and today to work on my thesis.  I stopped at the soccer field again to see what kind of wildlife I could find.

On Saturday, I saw an all-green bee that I assumed is an Agapostemon sp., and Silvery Blue butterflies again.

Chasing butterflies and dragonflies

There was no bus services today because of the holiday (Victoria Day); plus, I figure it's probably time for me to start doing some exercises by biking to school today.  When I was getting close to the school, I saw a path leading to a field that I never paid attention to before.  Then I saw the field was busy with butterflies and dragonflies flying around.  Definitely a great detour.

This was the dragonfly that I saw today.  I took some photos of it, and I think it looks like a Frosted Whiteface, but any feedback is appreciated.
