I think you will find these are actually separate subspecies rather than 'forms'.

The top photo is Neurosigma siva nonius Nicéville, 1896
see http://yutaka.it-n.jp/lim1/720870010.html
whereas the orange specimen is Neurosigma siva dalatica Yoshino, 2017
see https://yutaka.it-n.jp/lim1/720870020.html
You can see the distributions from the map in the links.
