Question about unusual Chrysina color morph.

[trehopr1]

So, I've been seeing this highly unusual color abberation of Chrysina victorina posted (which is purplish in color). My question for any beetle folks is HOW is this possible? I've seen my share of the species and have never seen a hint of purple present. I am quite familiar with the breeding efforts conducted upon Lamprima and even P. mulleri of Australia to get unusual color forms etc. (which tend to fetch very high prices). So is this particular specimen which is currently selling at $480 (with time left to bid); an example of someone's Herculean breeding efforts OR is this some sort of "Tom Foolery" taking place. Much like the unscrupulous individuals who would expose Victoria Birdwings to excessive U.V. light to get "bluish" specimens or something of the like. Has it been injected with something?
I don't want to sound like a novice or something in this arena; I just want to stay abreast of the latest developments in breeding or fakery going on out there.
I must point out that I find it unusual nobody has brought this question up regarding this specimen. In the past any "oddities" related to Lepidoptera are usually "pounced upon" by the Lepidopterist community and quickly dispatched as fakery, clever repair work/alterations or highly unusual aberrations not likely to be seen again.

Greetings,

On my first trip to Arizona, too many years ago to admit, I collected Chrysina gloriosa, C. beyeri and C. lecontei, and made the fatal error of placing them into alcohol for storage. A few of the specimens developed distinct blue blotches on the integument - looking like they had ink spots on them. Not all did so, but a few were bad enough that it permanently ruined them. I wonder if some chemical trickery is being used with the victoriana - it does not look natural to me at all...

Cheers!

Is it possible someone is cleverly injecting dye in very tiny amounts into freshly enclosed beetles whose exoskeleton has not yet hardened (to get such results)? I don't want to give anyone food for thought on this topic but, the possibilities need to be raised...
I have in the past (for example) found Passalid beetles within a rotten log in Ecuador and amongst the adults and larvae their were a few (red) colored freshly enclosed adults present; which eventually turned black.
What if someone has found a whitish a somewhat colorless pupal stage to experiment on? Or maybe they have found that fresh enclosures are the best for such experiments?
I suppose there will always be someone who is willing to push the boundaries of all reason if they can gain notoriety or monetary gain. Perhaps, this effort does not work with all that much success yet; hence the appearance thus far of this one and of one other of lesser quality.
