Photographed this week near Omkoi, nw Thailand.
The first three images I make as Flos asoka, as they match the literature and images on the web well. We saw several of these in the same area.

However, in the same area we also found another individual (images 4 and 5) Flos species which to my mind looks rather different. The width of the outer dark band in the forewing is considerably larger, and the indentation is different than the other individual F. asoka that we saw, and the colouration appears greyer (though this could just be the light/flash). Is this individual F. adriana?

It appears to match images on Butterflies on India of F. adriana quite well, but I am not aware of how much variation there is in asoka. My apologies for the rather poorer images of this one, but it was only present very briefly.

Many thanks.
