Leptosia nina, the Psyche, is a small butterfly of the family Pieridae (the sulphurs, yellows and whites) and is found in Indian subcontinent, southeast Asia and Australia. The upper forewing has a black spot on a mainly white background. The flight is weak and erratic and the body of the butterfly bobs up and down as it beats its wings. They fly low over the grass and the butterfly rarely leaves the ground level.
Unpublished manuscript of Lionel de Nicéville gives it the common name of "wandering snowflake". - Source: Wikipedia
I retired and thought I got away from supervisors. But no! These two standing around making sure I am mowing the lawn correctly. A neighbor was walking on the sidewalk and one flew over her which brought my attention to the fact that they were there supervising me. Probably hoping I would chase out a squirrel and not a neighbor.
