Butterfly in flight

Made a similar photo yesterday, and posted on my FB cover page today. Windy and warm conditions were similar today, and wanted to see if I could duplicate yesterday's photo.  On past attempts to duplicate a photo success was elusive, but being outside on a beautiful day is success in itself.

Getting this picture wasn't easy.  After 30-40 minutes and 160 attempts, this photo was taken. You have to find a butterfly which is feeding on a specific flower and staying on the same clump of flowers, pre-focus on the feeding butterfly, and watch for a slight opening of the wings signaling flight is imminent  Hit the shutter button and shoot madly and continuously, following the butterfly if you can.  Most shots will be out of focus, but with patience eventually you will be rewarded.

The brisk wind helped, as the butterflies only approached the flowers from the lee side flying into the wind.  Could therefore position myself and wait, enjoying the sunshine while knowing the direction of approach and that the butterfly would be flying more slowly due to wind resistance.
