Euploea mulciber male (Cramer, [1777])
Striped Blue Crow
July 24-26, 1999 - Laibin ou/or Nanning - Guangxi - China © Frédéric Vivien
This butterfly looks like an Euploea. Looking at dabrera1982 I was not able to defintively identify it. Because of the huge iridescent blue patch, I tentatively identify it as Euploea mulciber.
