Thanks Seow. I have removed the worn specimen from my site. I also recently shot an ochreous brown coloured Matapa with orangey hindwing cilia. So is the main distinction between M. aria and M. druna the ochreous colouring of M. aria or is it still better to distinguish based on the cilia? I have shots (one on the page linked above) that I think are M. aria because there is no contrast in cilia but the base colour is quite dark brown.
