This or a very similar specimen was offered on eBay maybe 10 years ago. It must be a fake, as there is no natural way a butterfly can have a hindwing each of two different species. Jan is correct that the wings belong to arcturus and bianor.

Bargain!!!!!!!!!!!!!!!!!! I'll have 2. Would have been even more of a bargain if all 4 wings were from different species. |

Yes but then the price would have risen to around $35,000, still a bargain, I'm selling a kidney to bag this treasure.

Can you summarise the opinions for those of us who don't understand German, thank you. Adam. |

maybe I should explain, why I think it possible. The principle is similar to a gynander. In the first cell division of the zygote takes place in mitosis, a "non-disjunction" instead, ie the chromosome in question, which for example is responsible for the color of one of the two species does not separate. This ends one cell with two copies of it, but the other with none. Incidentally, in the case of insects, the axes of symmetry are not determined by hormonal gradients, as in the case of vertebrates, but are determined on the first cell division. That's why it's even possible with insects. In any case, then the cells of one side are only descendants of the cell with the double chromosome and the other with the completely without. I hope that makes sense somehow and I do not speak. Maybe I'll make a mistake somewhere
*********************
This is one explanation which I find logical. the others think it´s a fake

"Maybe I'll make a mistake somewhere" ... yes, simply put the error is that P. arcturus does not carry the genes to code for a hindwing of P. bianor. Adam. PS. joachim thank you for the translation. |

It's such a shame, back in the day when she first started out Cynthia used to sell some good stuff at great prices, where did it all go wrong?
