"a Mr. Clarke" is the famous Sir Cyril Clarke who published many well known papers on genetics of butterflies. Here is his Wikipedia page: en.wikipedia.org/wiki/Cyril_ClarkeAdam.

I have been to Corsica a few rimes and numbers of both hospiton and machaon fluctuate a lot but hospiton is always more common.. One year I was there hospiton was incredibly common (c. 300 at one site in a couple of hours) and machaon was not seen at all, consequently all eggs obtained were pure hospiton. In another year there were a lot more machaon about and all eggs obtained from hospiton females were hybrids. Usually it is somewhere in the middle with an average of 10% of eggs being hybrids.

You must have discovered a hospiton eden. I have never heard of anyone seeing that many.

Timing is everything. In reviewing Tennent's draft of Butterflies of Solomon Islands one thing I noted was that his observation that G. sarpedon was rare in SI. My observations were otherwise. I saw more sarpdon in one day (for a week) than he'd seen in 18 months.

Top two are from Korsica. Then purported hospiton from Sardinia then a hybrid. From an old collection and I’m simply reporting what the old label says.

Shoot cant post photos from the phone app. Chuck You can post photos on the phone but you must scroll down and switch to desktop version ( due to all small things there it is rather difficult though ) Paul

Here is the specimen I'd mentioned 18 months ago; leg. A. Schulte, from Hanover Germany. The label is original to the specimen as far as I can tell.

I do not know about stone! Every specimen in my collection has a label prepared by me for uniformity. I have the same size label (.50" X .75") on every specimen, regardless of size. I originally hand wrote each label with a Rapidograph pen. Same size now but only printed from my Laptop to a high quality printer. I use a #4 Arial Font size.
A collection of specimens with no data has no scientific value.
I learned that lesson from the late J.F.Gates Clark of the Smithsonian back in the mid 1950's.

Any comments on my specimen from Hanover? Looks a lot like Hospiton to me but I’m no expert. Date is 1938 and I have no reason to suspect provenance. Also have another old machaon from Germany that doesn’t look like this one.

It is not a real hospiton.
Could be an hybrid machaon X hospiton or an aberrant machaon.

I'd guess a hybrid.

Interesting because the collector is well known and respected. One would think if I were a hybrid it would be labeled as such as the other one is. If it’s a freak it’s an interesting one.

It looks like what I thought you meant when you originally mentioned this specimen, a spring form specimen of P. machaon gorganus. I replied suggesting that was the likely identity of the specimen back then "Probably your Hanover machaon is first generation, which is smaller and darker than the summer form." Adam.
