Les Day told me that it is quite rare on Koh Samui, but I have some specimens from Koh Phangan collected on the hill at the south side of the island by my much lamented friend Prasobsuk Sukkit in early April 2013. They are all very similar to the holotype.

By the way, for the interest of readers, the nominate ssp. adamsoni reaches at least as far south as Petchaburi at the top of the Peninsula, and probably is also found in northern Prachuab Kirikhan. There is a dry zone on the Thai side of the peninsula at that province which is a barrier between the southern and mainland Thai populations of many species/subspecies. Some are able to cross it and some others are distributed up the western Burmese side which is not so dry and cross back into Thailand at the top of the peninsula, but quite a number of butterflies do not cross this area.

I got this specimen back in Poland in 1985 without any data, I suspect it is Papilio helenus but what ssp. it could be and possibly from where? Looks like nominate: helenus?  |

Yes it does look like nominate helenus, so it's not possible to say where it came from.

Fantastic drawer Paul ! ! All wild collected no less... Spot-on fresh hatch kind of stuff and as always a masterful prep job on each and every one.
I noticed in the 1st column that the first two males have hind wings which appear more slender in their proportion than the two lower males which have very broad (huge) hindwings. Any reason for this?
Also, the last 3 columns are stunning in their white/pink mix of coloration. Somewhat reminds me of P. ascanius specimens.

Thank you trehopr1.
Second male is slightly smaller than others. The hindwings are a bit slender but I suppose it’s just variation.

Papilio polytes also has a male-like female form called cyrus in ssp. romulus (other subspecies have different form names), which is a recessive gene, so only expressed when the butterfly carries a pair of the gene. I have found that heterozygous females (ones carrying one mimetic gene and one male-like gene) often look like the female at the bottom of the column, with the white hindwing patch in a band rather than a round spot.
Papilio helenus can be found at higher altitudes than P. nephelus which is generally not found above 1000m. and is a wet lowland forest species.
Did you find nephelus on Koh Tao?

No, I didn’t find P.nephelus nor helenus on Koh Tao, polytes and demoleus are of course very common there.
Female forms of polytes are indeed interesting.
I didn’t find f.cyrus yet, I suppose they are rather rare and perhaps overlooked due to similar look of males.
Heterozygous females are also uncommon.

No, I didn’t find P.nephelus nor helenus on Koh Tao I thought you might not, it's probably too dry for them there, nephelus particularly does not like dry habitats. Also of course, presence of host plants would be a very important factor. P. helenus can use a much wider range of Rutaceae than nephelus, even happy to lay on Citrus, whereas nephelus prefers Micromelum, Zanthoxylum and Clausena spp. The cyrus form of the female is not very rare, but does depend on the frequency of the gene in the population, similar to the butlerianus form of P. memnon agenor which is also a recessive gene, but in places where the model for butlerianus, Atrophaneura varuna female, is present it is not uncommon (Malay Peninsula and NE India). As you say, it is easy to mistake form cyrus for males and thus ignore them. Adam. |

Wow, those polytes romulus females are nicely variable. I notice on the hind wings that some have 2 cells in white while others may have 3 or even 4 ! Also, the burgundy coloration present on the hind wings also varies in it's amount. That 3rd female in the column is simply awesome ! ! 👍😎
I think that I would simply have to FILL a drawer with just the females alone. Maybe a drawer and a1/2....
Also, love those 1st two columns of those species. Big busters....
Nice Papilio species out there in Thailand Paul. Really nice, and you are most fortunate that you can experience collecting all of them yourself rather than have to buy them papered like just about everyone else has to.
Bravo!

Drawer #4 Family: PapilionidaeTribe: PapilioniniGenus: PapilioCol.1 Papilio paris paris Linnaeus,1758, males, common species of mountainous regions of Indochina except Malayan Peninsula can be found also at lower elevations. Col.2 ( from bottom ) Papilio arcturus arcturus Westwood,1842. male, uncommon species found in northern regions of Thailand at higher elevations. Papilio daedalus C. & R. Felder, 1861 male, female, this species is native to Philippines and one of fewer butterflies I purchased in the past. I have include it in this drawer due to close relation to P. palinurus palinurus which occurs in peninsular Thailand
Papilio paris paris Linnaeus,1758, male Col.3 Papilio castor mahadeva Moore,[1879] males, locally common in forested areas in all Thailand and Laos except far north. Col.4 Papilio alcmenor publilius Fruhstorfer,1909 males, very localized species can be found in numbers in its habitat only in North Thailand at higher elevations Col.5 Papilio alcmenor publilius Fruhstorfer,1909 males form leucocelis
