Well, I see Nomad that the EVER popular Papilionidae still remain rather pricey generally speaking (as a group); unless your only looking to buy the most dirt common ones. I was wondering what is exactly going on in that 6th photo you took. There is a series of 6 Cetoninae in the right corner which all have a funny reddish tone overall. Two are Goliathus (albeit smalls). Were all these specimens perhaps killed off before their cuticle (exoskeleton) had time to harden and darken? I have found Passalid beetles in groups under logs and usually among them one will find freshly enclosed adults which are red in color initially but, hours later are black like all the other adults. Glad that you took some pic's of some saturniids and catocala. Something different and nice to see !

The rare or uncommon Papilionidae always command good prices for quality specimens. Not being a Coleopterist I do not know the reasons for the pale Goliath and the Mecynorrhina and the others. You are perhaps right, can others share their opinions. I have enlarged those specimens.

Nomad,
Do you recall who the dealer was who had the two male P. buddhas at the upper left of the case in one of your photos?
Thanks, JHyatt

Jhyatt. I am afraid I do not know that vendor's name. I know a few of the established dealers by name but not all of them.

I am not sure you could buy this collectors item-art and then there is the space to consider. Certainly a new species I believe.

Were all these specimens perhaps killed off before their cuticle (exoskeleton) had time to harden and darken? It is the considered opinion of several other collectors on a sister forum that those pale specimens have been either bleached or exposed to UV light, thus they are artificial specimens.

Actually, I would agree with trehopr1 at first glance. They look just like this ladybug that I took pictures of while it dried. Within an hour it was dark orange/red with dark black spots. You can kind of see where they will show up if you look close there are clear areas that eventually turned black.

Thank you Nomad on the answer to my question regarding those reddish-toned Cetoninae. There seems to be all sorts of " Tom foolery" going on out there in our hobby in an effort to come up with "new" never before seen oddities for the uninformed to collect ( and spend money on) ! We have U.V light exposed birdwings being passed off as ultra-rare abberations, hybridized species of birdwings that would never happen in nature, temperature shocked chrysalids producing very weird morphs of very ordinary species (Inachis io), beautiful Papilio species like (Ulysses) with cleaned scale free zones in their wings, and now Coleoptera exhibiting a case of sunburn ! Buyers out there beware. These cheap imitations are never worth the asking price. Go for the genuine article or at least a genuine abberation and you can't go wrong.

It is amazing what lengths some will do to get your money, at least the 99 per cent is genuine material

I think that it probably depends on the specimen and it's coloration. If you look at this ladybug, the head was already black and white when it emerged, but the elytra were all pale still. I would say that these are under-dried specimens because the white patches don't look white. If you UV bleach something you expect the white to stay white and the other colors to fade more. The white patches on these specimens look more cloudy.

I know this is Stretching it a bit for an entomological forum but I like this. Seashells and an egg.
