I just realised that I haven't posted the underside photo of the natural hybrid for comparison, so here it is:

you did it yet Adam on collector secret (not on insect net .... )

So I did, Thierry.
PS. 'already', not 'yet' would be the correct word in English.

Today another 5 males hatched and they were all obviously Papilio polytes hybrids, similar to the first specimen. They all had visible vestiges of the marginal white spots on the forewing edges particularly near the tornus (not present in the natural hybrid), as well as similarities in the hindwings.
As a result I am more confident that Papilio polytes is not one of the parents of the hybrid, which leaves P. prexaspes pitmani, P. helenus helenus and P. nephelus chaon as the other species which occur at Khao Soi Dao, Chantaburi, that could be the other parent. However only the first species is really a likely candidate judging by the appearance and size of the natural hybrid. Also, when I tried to cross female Papilio castor with P. nephelus chaon I was completely unable to make them pair successfully despite many attempts, which makes it less likely that these were the parents.
When a female pupa of the hybrid emerges I will post a picture.
Adam.

Today a female emerged, and it is rather interesting. Here are photos of the upperside and underside:

Adam... how do you get different species of Papilio to mate to create the hybrids ? Do you simply put them in a breeding cage together or is it done manually somehow.

how do you get different species of Papilio to mate to create the hybrids ? I assume he uses some sort of "hand-pairing" technique. If you google "hand-pairing" a fair amount of info is available.

Yes, hand pairing is necessary for most hybrid crosses. Hand pairing is not difficult to initiate, but some pairs don't want to lock genitalia together at all and are more difficult actually to get a successful mating from than others.
I have just received some pupae of Papilio 'polytes' ledebouria, which were kindly sent me by a Swedish breeder who won't be able to rear them any more this year. It will be very interesting to see if they will hybridise naturally with Papilio polytes romulus from Chiang Mai or they will also need to be hand paired. I suspect they may mate naturally although they are actually different species, ledebouria is actually a subspecies of Papilio alphenor. I have noted significant differences between the pupae of ledebouria and polytes romulus already. Papilio polytes is a relatively easy species to make hybrids with, so hopefully I will have some joy crossing these. It will be interesting to see if the hybrids are fertile or not. I will let you all know here what happens in due course.
Adam.
