Adam, thanks for the clarification. From Hokkaido I was given the female Papilio maackii jezoensis early summer form-Japan, Hokkaido, Otofuke-cho Kato-gun Osarushinai. 28.06.2014. It is much smaller than the summer generation and larger than the spring. But I admit that I can not be sure that this is really an early summer form and not a commercial trick because I have males from Hokkaido, Kato-gun, Otofuke-cho, Tokachigaoka, 06.07.2017. The interval between dates is quite small. Or the early summer form and intermediate generation is not the same?

Just in case, here's her picture. Of course this is not a topic Papilio machaon but as a matter of intermediate generations. Attachments:

Or the early summer form and intermediate generation is not the same? This is a difficult question to be certain about, and may vary between species. The offspring of early spring form specimens tend to be smaller than summer form and either like spring form specimens but larger, or like summer form but smaller. Almost certainly this is a result of daylength and temperature during the larval stage. It is worth bearing in mind that as well as some spring form specimens hatching before others they will lay eggs over a period of several weeks, so that the larvae of early eggs receive different environmental stimuli than those from eggs laid by the same parent a couple of weeks later. When I bred hippocrates here I separated actual generations, and the offspring of the first generation to hatch after diapause were a larger version of the spring form, and the 3rd generation of the year were the large summer form with double black chevrons. The important difference is that here the daylength is about the same all year round, a lot less variation than over the same time period in Japan. I suspect that the actual number of generations in nature is much less important than the environmental stimuli the larvae are subjected to. Thus in Hokkaido there may only be a spring and summer generation (although there may be a partial 3rd emergence in early autumn of 'spring' form specimens) but the 2nd generation specimens may vary depending on when they were larvae. Adam.

Could someone tell me what subspecies of Papilio machaon I have here. I acquired this nice example about 20 years ago from a small collection which was being parted out. I found the locale interesting at the time...

Ah yes, this is a nice summer generation ssp. syriacus. The strong yellow colour is due to hot weather, and can be seen in several subspecies of machaon.
Adam.

Thank you Adam so much for the I.D. !!

Yes, syriacus. Simply delightful female! In addition to a rich yellow color, as noted by Adam, the subspecies is often missing the black coating in the anal region of the rear wing, from its Foundation to the red anal eye.

Friends, all good mood! Maybe someone will be interested to see a small report on Papilio machaon in the Central part of Sakhalin. Russia, the far East, the West coast of Sakhalin island, the vicinity of the district of Aleksandrovsk-Sakhalinsky. In this area, from 17.06.2018 years, was made an approximate count of the number of instances of Papilio machaon by the routing method for the purpose of comparison of population of different regions. For this study, the same weather conditions, time and distance, similar to those established to other areas, were chosen. The distance of 6 kilometers done in 2 hours allowed to collect a number of samples of Papilio machaon to compare them with samples from the South and North of Sakhalin. In total, during this time there were about 30 copies, of which 75% are males and only 25% females. Thus, we came to the conclusion that on the West coast the population of Papilio machaon is much smaller than on the East coast - Smirnikhovsky district, the river Pilenga, where we have counted about 60 specimens in the same percentage of males and females for the same time and distance. In comparison with the calculation of the last year, the data have not changed, the number of Papilio machaon is not reduced and is kept at the same level in a fairly large number.

Hello friends and colleagues on hobby! As I wrote earlier, I received some material from Belarus. I present them to your attention along with samples of nearby Southern and Eastern areas some of which you've seen before. It's a shame that living in Moscow I have only three samples from my region, there is always not enough time to assemble a good series and as always postpones what's next. However, judging by the same pattern is clearly seen as a female in the Moscow Region photo number 16 is different from the females from Belarus, Ukraine and Crimea, photo number 6, 12, 13. We must try this year to collect more local samples. Link to the photo piccy.info/view3/12494844/ace45f73b4c22c2eab01cac74d750136/orig/

Very interesting to see specimens from Belarus. I note that it is not possible to save photos from the link you provided (right click disabled). Here are my spread Ukraine and western Russian machaon. I don't have any specimens from Moscow region, the nearest is from Nizhny Novgorod: Russian literature (such as Tuzov et al 1997) treat northern populations as ssp. machaon and southern populations as ssp. gorganus, but I cannot see any reason why any of my specimens in these draws should belong to a separate subspecies from gorganus. I prefer to treat ssp. machaon as coming from Sweden and Finland. Perhaps St Petersburg machaon could also belong to that subspecies, but I have not seen it from that part of Russia. The specimens from Novosibirsk and Kemerovo come from much further east, but look very like the western Russian specimens. Adam.

Adam, Hello!
Yes indeed a strange image hosting where you can add a photo but it is impossible to save it. I used the link because I can not insert a picture on the forum, shows (Error: This forum has exceeded its attachment space limit. Your file cannot be uploaded). Strange, You did it. Adam, I'm guessing samples from St. Petersburg could be nominated in both Sweden and Finland, but the thing is, I haven't seen any nominative Swedish or Finnish samples. I have a photo of some samples close to St. Petersburg but how to attach them to the forum due to some error? If you want I will send you a photo to email. Today I was talking with a colleague from St. Petersburg, he will try to collect a certain amount of samples, I hope he will succeed. I also ordered 28 dolls from Volgograd. it is clear that there is a typical ssp. gorganus.

Maksim,
Join imgur.com, it's free! After you sign up and log in to the website you will see your user name at top right.

Next click on the image you want to post here and you will see it on the left with a link menu on the right. Click "Copy" next to the link labelled "BBCode (message boards & forums)", then just paste the link in your post on the forum in the place you want the photo to appear. This way you can post as many photo links as you want inside a single forum post, and also it doesn't cost the forum owner anything in hosting fees (unlike if you upload a photo as an attachment).
Adam.
