A bit dark, but lifting the gamma to around 2 gives a good pattern.

I'm not certain, but I think it is this Pyralidae

I'm not sure about this being A. hologramma. Looking at a lightened and blown up image in Photoshop the specimen seems has a zig zag pattern marking towards to apex of the forewing which seems to be missing in the examples labelled A. hologramma on the ALA.

If the hindwings have no pattern, then the forewing aspect ratio (costa length/width) of this specimen would be about 2.0 +- 0.1
That of A. holophragma is about 2.7 +- 0.1
No way Jose.

Could you email a copy of your enhanced photo Ian?

Hi, I don't know if it will help, but i have added a second photo. This one i took without a flash, as normally i do not use flash at all. But it seemed dim, so I took another with flash, which I though was clearer, so that is the one i put up.

Glenn, Don’s emailed attachment shows it well.

If it's Metasia, then liophaea looks closest. Looking at the second photo, I'm still uncertain and will look some more. Definitely not Assara.
