Common Yeoman

Sorry Viv, not smart enough for this, Butterlies of Iddo-China have images and spotting maps that may or may not help. Cirrochroa tyche mithila http://yutaka.it-n.jp/hel/710170010.html Cirrochroa tyche rotundata http://yutaka.it-n.jp/hel/710170020.html Mr Les Day (Samui Butterflies) Koh Samui not being far from you, has a spotting he has marked as Cirrochroa tyche rotundata. He seems good on his ID's.
