I am glad you like the vodka method ! A game-changer !

chuck < you shoud try with vodka as explained, as your method doesn't seem to work : wings must not be wet at all.
With the vodka method, specimen look like a fresh specimen (they are not soaked, they have no humidity drops), with easy-to-move wings.

The photo of OP is signed by Luis M. Constantino.
I assume that this is Luis Miguel Constantino, a well-known researcher and entomologist from Colombia.
He has posted quite a few pictures on Flickr with similar photographic skill.

Since Flickr is not a scientific website, manipulation of the images posted there is legitimate in my view.

I personally think it is pinned specimen placed on the leaf.
There are only few species that rest with almost 90° angle and C.panariste is none of them as it can be looked on many other photos on internet.

It's a male Asterope sapphira.. then known as Callithea sapphira. From Brazil. Here are a pair from my collection.

The painting does resemble a Eunica in colouration more though.Like the male Eunica alcmena from Peru in the second picture

The panariste photo that started this discussion bothers me in another way which I don't think has been mentioned... it looks to me as if the left fw apex is casting a distinct shadow on the leaf, but the left tail isn't. The tail would have to be lying flat on the leaf to make this happen, and I don't think the butterfly is likely to adopt such a posture. And I agree that the colors have been fiddled with!

It's my experience that no butterflies of any size are ready to set in 24 hours; usually 2-4 days. If I get the same results, I'll go buy a bottle of Vodka and try again.
Chuck,

Guess you don't relax many blues and hairstreaks! Mine are usually ready to spread after relaxing overnight in an old-fashioned relaxer, with water-damp paper towels and some antifungal. But bigger stuff, even larger skippers, are a whole other ball of wax. I usually relax them 12-24 hrs, inject water, and return to relaxer for another day. Generally ready to go then. (I'm never in enough of a hurry to bother using hot water).

Interesting experiment you did. I really don't understand what the alcohol brings to the party, unless it lowers the surface tension of the water phase and wets the bug (inside and/or outside) faster as a result. I can't imagine any reason why ethanol or isopropanol would behave differently from each other. Both alcohols are usually sold as a water solution (Isopropanol is usually 70/30 alcohol/water, and "pure" ethanol is generally 95/5; vodka of course has more water than this), so any of these would have plenty of water to moisten a butterfly.

I'd bet dollars to donuts that pure, 100% ethanol or isopropanol alone would be very poor at softening butterfly tissues, but being retired from the lab I can't do the experiment. Anhydrous alcohols are quite hygroscopic and pull in atmospheric water quickly. Ethanol levels off at the 95/5 point, a "stable azeotrope" in chemist lingo. I don't think really anhydrous alcohols could be bought, save from a lab supply company, and they won't sell to individuals.

Cheers,
jh

I have a specimen from the 1970s labeled Dynastes (Augosoma) centaurus. And, I can remember it being listed as such in a catalog, can't recall which, and I'm sure I don't have the catalog anymore. Whether in the 1970s it was labeled as Dynastes because that was the trend, or because it made the species more marketable, I can't say.

I have often seen the name "Dynastes centaurus", but as Eleodes mentioned, "There seems to be no record of either (Augosoma) species being formally known as a Dynastes species". It appears that Augosoma centaurus must have been classified under Dynastes at some point however, even if only informally. The name Dynastes centaurus appears in Dru Drury's Illustrations of Exotic Entomology (1837) -

https://commons.wikimedia.org/wiki/File ... y_I_36.jpg

Note that Xylotrupes gideon also, was formerly referred to as a species of Dynastes, and prior to that, Scarabaeus (Linnaeus, 1767).

A more recent example is Bowden (1959) -

https://journals.co.za/doi/pdf/10.10520 ... 28789_2767

Some further digging through the literature might possibly reveal when and how Augosoma (and Xylotrupes) came to be placed under Dynastes, but in any case, it must have happened sometime after MacLeay (1819), as that was the origin of the genus name.

Many thanks for uploading that; always interested to see insect-related memorabilia.

Thanks to all for your comments. I'm now of the opinion that this image has, at the least, had its colors digitally intensified.

The photo was likely just edited, no need for photoshop. Just turned up the brilliance/vibrance dial in editing and you get a beautiful brilliant photo, but sadly not what it really looked like. No doubt it was a beautiful, but the colours not quite what show in the photo. I see it all the time.

Pyronia tithonus

by daveuk » Sun Dec 04, 2022 12:43 pm

Some self collected specimens from the past ten years & pictures taken this summer of a pair of this species in the wild. A small but lovely satyrid still reasonably common in my part of the U.K. Sexual dimorphism is quite marked in this species.Females on the left. Males on the right. There is also variation in the number of black spots in the forewings of both sexes. Commonly known in the U.K. as the Gatekeeper or Hedge Brown. Aptly describes the type of habitat they prefer.

Thank You 58chevy.
I have known about this species from a very early age. I will be 65 in January. When I was six in 1964 the Brooke Bond Tea company here in the U.K. issued picture cards in their packets of tea for the series Butterflies of the World. Pictures of front cover of the album & the Consul panariste card & description. Described here as Anaea panariste.
The album I had when I was six sadly disappeared during house moves etc. Luckily this series is still available relatively cheaply on ebay. Many thousands of the original cards & albums were no doubt printed.

I think this photo was taken with flash (see the white flash reflection at the bottom left), and then it will have been enhanced using software.

Flash often makes structural colour such as the blue on this specimen more vivid, but I doubt that flash alone will have resulted in this photo. Nowadays it seems most photographs (nature or otherwise) are 'tweaked' at least a little.
Trehopr1 wrote: Sun Dec 04, 2022 12:12 am I would also add that it almost looks like this butterfly was photoshopped onto the leaf of the background because the butterfly has its proboscis extended like it was drinking at a water puddle however, the leaf itself has no water droplets on it.
I doubt that this butterfly was photoshopped onto the leaf. There may well be a small patch of something (maybe liquid bait on a piece of cotton wool or tissue) directly below the butterfly. With the butterfly immediately on top of the bait it is invisible in the photo.
