Thanks. What I am looking for are some criteria for deciding from the underside alone. I am not sure they exist...

This is one of 4 very similar butterflies reported from this area, and as far as I have been able to read, these cannot be safely distinguished from the underside alone. One source is Torben Larsen's annotated checklist of Delhi butterflies. Here is a summary of the possibilities according to [Larsen]: Striped Pierrot (T nara) - (Includes extricatus and alteratus. T extricatus seems to be usually called "Rounded Pierrot") - most common Balkan Pierrot - (T balkanicus) - rare Indian Pierrot - (T indica) - larger than T nara, uncommon, but consistently present in some localities.( Larsen lists some localities in South Delhi) Spotted Pierrot - (T callinara) - more "macular" (ie, blotchy) markings than in other 3, which tend to form continuous bands. Uncommon/rare. T callinara may be eliminated by the markings. From the other 3, T nara is most likely by its reported commonality. Can one do better than this?
