The black-and-white upperside wing patterns are very similar to a few other Sailors or Sergeant species. A very well-documented of the life history of this species can be found here.
Grey Pansy (Junonia atlites atlites) seems to be a permanent resident in this wasteland. There were at least four individuals frolicking under the morning sun, executing their typical flapping-cum-gliding flight pattern. They usually landed on the leaf surface after a short flight, with both wings folded, displaying the rather unattractive pale grey undersides.
