Try and error...

I tried to catch an flying butterfly - but so far this is the ugly best I can show (+ some PS treatment to blend in the blurr).

Wow! You tried to catch one of these things in flight. Amazing you even got it in the frame. These little buggers flit and fly so freaking quick.

I have to agree with Iggy. These things need a dose of Ritalin!
