A species of Penthema, but I am uncertain of which one.

I asked Yutaka Inayoshi, and he said it is Penthema michallati michallati Janet, 1894, see https://yutaka.it-n.jp/sat/40570010.html for a little more information, but no photos.

Looks a lot like this Papilio from Taiwan. Must be regional mimicry with similar pairs of sp. mimics?

[adamcotton]

That's Euripus consimilis (Nymphalidae). I suppose it could be a Danaine mimic.

Oh, and there's a huge size difference, E. consimilis is maybe 3-4cm across spread, whereas Penthema is nearer 10cm.

That's Hestina assimilis, not Euripus consimilis, Adam.

Kuni,

Thank you, my error!

Anyway it is definitely not a Papilio as stated in the post containing the photo.

Looking on iNat, I find Hestina assimilis ssp. formosana

Can't post pics because my anti-virus software says the photo hosting platform I've used has a virus.

I thought it looked like a Papilio, oh dear it's in the wrong drawer.

[adamcotton]

Yes, Euripus consimilis is similar but has a different wing shape. I got confused by the presence of the red spots, see https://yutaka.it-n.jp/apa/750300010.html

Kuni,

Thank you, my error!

Adam.

First clue in the photo would be four legs instead of six in Papilio.

[adamcotton]

Indeed, and the distinctly pointed palps.
