Dear Sir,

Thank you very much for your clarification about my butterfly.

But sir, I am little confused about the link you ve sent for P. sandaka as it is written P. hordonia in the photo. Does this mean they miss identified the specimen?

Thanking you

I am afraid there are a lot of error images on the net.

The male of P. hordonia can be positively IDed by the smaller grey speculum on the HW but this is often hidden.
The orange line & bands are well separated by a grey which may be irregularly constricted.

P. sandaka davidsoni. The white speculum is larger & cut into the upper part of the orange band.
The orange line is wider & touches the inner broad orange bands ,the grey line in between is mostly missng.

The male below is P. hordonia probably as intermediate dsf, the small HW grey speculum confirms it.
This was taken in January.

Compare this male P. sandaka also taken in January in southern India.

Thank you very much sir. Things are very much clear now.

As I was checking my Lascar photos for comparison, I got this one taken from Cherrapunjee, Meghalaya (India) in the month of March. I see that the grey line separating the orange line from the orange bands is broken at few places. So, can we conclude this as P. Sandaka?

Thanking in advance.

Post 5 Yes it is a male P. sandaka.
This one is unusual in that the orange line is poorly developed.
Normall the orange line is very prominent in sandaka.
However, this particular male sandaka below also has a very poor orange line.

In some examples it may be difficult to tell the females apart ie the female dsf hordonia is very similar to sandaka.

Now the grey line is clear to me.

Pardon my shortcoming, but with all my effort, I am not able to point out what is the "long foot of the post discal band" which seems to be the characteristic of the male lascars. Please help me understand this.

If you look at the FW postdiscal band which is just to the inside of the orange line it has a rounded head and a long 'foot' which runs along the lower margin towards the base.
The foot is variable in P. hordonia but usually long in P. sandaka.

The females of both species have a short foot & so can be identified.

Ok, now I understand. Now this two species are very clear for me. Thanks a lot.

Until next time when I come with another UFO.
