And then .. sorry I cant skip that ... climatic change. Species are moving to new places , also on same place weather is changing and dramatic weather anomalies are present frequently and surely phenotype will react to changed conditions.
So as for me - as long as specimen has correct label information with all relevant data, it is OK. And it is only decision of collector if he find value of such specimen for his study/collection.

Fumigant Lifetime
by jhyatt » Mon Nov 20, 2023 8:53 pm
But I wonder how one can tell when the fumigant is exhausted and should be replaced. I've been doing this when the originally deep yellow squares fade to a very pale yellow color. This takes about 3-4 years in a drawer of average tightness, in my experience.
Am I being risky and should be replacing them more often? Or am I leaving money on the table by replacing them too frequently? Does anyone have any actual data on the useful lifetime of dichlorvos strips?
Cheers,
jh

I think it is desirable to find morphological as well as sequence differences when naming something.

It's the caterpillar of a geometrid moth, commonly called an "inchworm" -

These caterpillars usually mimic twigs of the plants they feed on, to conceal themselves from predators such as birds.

Given that one could well argue that COI is better at differentiation than morphological comparisions it seems this gap is more reliable. Given that, I've read several papers lately that show COI for broad-ranging taxa that are broken into clades (or some such) and so long as it exceeds 1.2% (or pick a number) then Joe Anybody could jump and describe dozens of new species based on the gap alone.

I also like Klee Diagrams, but that may be because I'm not so interested in proposed evolutionary lineages (and as Adam has pointed out, sometimes the different trees conflict with each other) and more interested in evidence supporting the existence of separate species.

Interesting. With so many potential crosses, the possibilities are almost endless.wollastoni wrote: ↑Mon Nov 20, 2023 10:47 am Trehopr1 < the "strange" Agrias you see on the market are not aberrations or man-made aberration. They are man-made hybrids from the Peruvian Agrias farms.
I highly recommend the new book of Philippe Floquet who illustrates all Agrias natural forms and all know Agrias hybrids : https://marketplace.insectnet.com/item/ ... embre-2023
I wonder if it will go the way of freshwater Amazon Anglelfish (Scalare)- so much crossing and thousands of generations later, the standard fish is a sad comparison to the wild fish; oddball morphs have come and gone, some because the resulting crosses produced fish that had too many problems. Now, the real enthusiasts are after what was imported 50 years ago- wild caught fish. I see this too in Papilio ulysses and other flashy species that have been bred on farms now for 30 years: generic, look-alike specimens that don't have the size nor variation of the wild butterflies.

With the lone exception of the genus Agrias most singular species produced of Nymphalidae are also pretty incredible and yet, are readily discernible from anything natural occurring.
All of these "specialty pieces" still tend to sell on the high side of pricing because they are a one-of-a-kind's and only a niche market of collectors out there can afford them.
However, I humbly believe that Agrias aberrations are the one subject group that is truly oversaturated in this regard....
The lines have truly become blurred between what is a hybridization of two species and what has been produced via chemical alteration. One now finds that even amongst some of the standard hybridized stock there are (singular) individuals which will stand out from all the others.
Are these singular one-off variations of a hybridized species (just that) or are a few select pupae pulled and treated chemically so as to produce a small assortment to garner higher pricing ?
It's really become challenging with Agrias to know what it is you're getting with these altered specimens but, under MOST circumstances they are obviously not natural occurring.
So, I don't necessarily see the harm in anyone producing these incredible creatures because I do believe that most of us who are informed and intelligent about this hobby would never mistake 98% of these butterflies as anything from the NATURAL world.
As with any other hobby or passion one must stay informed, be wise, be questioning, and above all else NEVER allow yourself to be gullible about something which just doesn't seem right.
Natural occurring aberrations will always be held in high regard because of what they are and by way of those who collected them. If you make such a unique discovery yourself try to tell some fellow collectors about it and if nothing else at least place a special note of data alongside it or with it to indicate pertinent information.

Some pretty amazing aberrations have been made by scientists with gene editing CRISPR. How long until that's available on Amazon for under $100? Then wait to see what happens.
If you must have a collectible which is at risk for fraud, the only things you can do are (1) become an expert or (2) have a reliable source. If it's too cheap to be true, it probably is.

of a hurdle with hybrids.
When money comes into play, all bets are off. Just like the ready made "collectibles".
