Spring Azures show a beautiful blue color in flight. The ones I saw today were either flying around shrubbery or travelling low to the ground. It seemed once they landed and I approached to photograph, they would immediately lift off again and head to other parts. They were either sensitive to the vibration on the ground or extremely shy.
