Thank you so much Dr. Seow.

I am sorry most of the photos were not of good quality. Actually we took clippings from videos.
Still you have given us proper ids.

[gkbaliga]

I hope you write a book on identifying butterflies Dr Seow
(If you haven't written so far that is)

Please let us know if you have already written or planning to write.

I have thought of that but it is just too difficult.
Most of the IDs as you may have know by now are based on an educated guess, by checking the descriptions, the images available, comparing the markings ,cross checking other species in the same region, eg S. India 5 species of Potanthus, Sri Lanka 3 similar species, Taiwan 2 species confucius & pava similar, etc.
Species also varies a lot & across different countries.
Many images have only the underside view & the label may be incorrect.

I am leaving this on hold.

TL Seow: Cheers.

Very true Dr. Seow

I being in South India have made my notes on the 5 Potanthus species occuring here, but still doubt crops up, just as an example.

Thanks for everything
