In the sometimes shady world of certain butterfly dealers on ebay, we get all sorts of strange things, after the recent discussion on the Brit arion specimen, is it from the UK or not, in the end it sold for £100 pounds, what do you make of this. To me it looks like the shortened antennae has been glued back on, I see no difference in the wings or am I missing something. See here

The left side is darker than the right side and the head is tilted a bit. I don't know how much of a difference is there between the sexes in this species. I once saw an Aglais io gynandromorph at an insect fair which was also hard to spot as there is only a minor difference in wingsize in that species. Radusho's explanation makes a lot of Sense, I would think that too.
Recently, we saw on the internet a proposed sale of a so-called new subspecies of Parnassius davydovi, described as coming from the same mountain range that Churkin discovered the butterfly! The "new subspecies" proposed for only 1200 euros !!!
No, I did not see the topic "davydovi risto" on the ICF.
A few years ago, the group of entomologists with whom I was in Kyrgyzstan, met S. K. Korb on the Dolon Pass, a site rich in Colias and Parnassius delphius, including the black delphius. This Korb made a memorable and somewhat extravagant impression. I understand he has a certain reputation in Russia.
Here are four pictures (2006 and 2009) : - the Dolon Pass - Parnassius (Koramius) delphius albulus Honrath, 1889, from Dolon Pass - the Moldo Tau Range - Parnassius davydovi in the Moldo Tau Range
I specify that in Dolon Pass, Parnassius delphius is common. The white samples flying everywhere, against the black fly only in scree stone and pebbles where they are difficult to identify (homochromic) and difficult to capture because of the slope and instability of said stones.
jmg it looks like a fantastic place. Your spread delphius specimen looks perfectly spread and even the body is not squeezed at all. How do you treat your butterflies after catching them in such a remote place. Do you paper them dry them and just take care that the bodies are not squeezed so they become flat? Or do you somehow spread them already or keep them moist until you are at home?
Things happened in the usual way: captured, butterflies are placed in paper bags. Back in France, they are moistened and fixed on the setting board. On the other hand, during this same stay in Kyrgyzstan, one of my friends, a specialist in Lycaenidae, practiced the display on the spot. In the morning, collect, and in the afternoon, spreading butterflies! This facilitates and greatly improves the preparation of butterflies, especially those of small size. But requires adapted equipment! See the attached picture!
Very impressive! That’s the first time for me to see someone spread specimens during a collecting trip. But he had to keep them on the spreading boards for transport probably? That’s also a question of space if you travel by airplane, really interesting! Thanks a lot for this photo! Always something new to learn.
It is the first time I see a such "spreading case" for "usual" butterflies or moth. This practice is more devellopped in micromoth world for which spreading is a critical point. I learned it with a microlepidopterist (Pyralid collector but also Tinaeidae, Pterophorid, Plutellid, etc...). This is done with small flat (hard) plastic box covered with a cover of small emalene plate on which very small pin (minutie) can be used. Surface needed is of course quite small (and then can be used easily during travel) and the job can be done even in far countries immediately after killing (or in the morning) and in the wild for day caught one. I think that some museum's team (as NHM) uses this method.
s'il n'y pas de solution c'est qu'il n'y a pas de problème ! akuna matata ....

Yes, that was exactly the way we did it when I was collecting microleps with NHM people visiting me here. We used to catch the moths live in small plastic tubes with screw-on lids then just pop them into a cloth bag which would go into the freezer when we got back home.
The next day, before going out trapping again, the moths would be removed from the freezer, allowed to defrost and then spread straight into small plastic boxes with plastazote in the bottom. We used a micro-pin through the thorax, then pinned the moth upright on the plastazote and used a needle to spread the wings out on either side. Almost always the wings would just sit in place without any need to hold them there, and the moths would dry out very quickly as they are so small.
