Zacatak. What a beauty and what a rarity. I have heard that this species is endangered in Taiwan due to the loss of its montane forest. Has been called the treasure of Taiwan. Below is a link to a very lovely image of this Swallowtail. www.flickriver.com/photos/cleanylee/521037350 |

You may be interested to know that 'Agehana' is related to the South American Papilio species, like the other mimetic Asian group known as 'Chilasa', and both of these are not so closely related to the Asian Papilio species.
Of course maraho and elwesi (probably just subspecies of the same species) mimic Byasa polyeuctes, and the dark form of elwesi tends to be commoner where dark Byasa occur; so for instance elwesi in N Vietnam has a while patch on the hindwing as all the polyeuctes there have a white hindwing spot.
It is also worth noting that elwesi/maraho doesn't have true tails like many other Papilio species. The tails of these have 2 veins, and are the result of a modification of the shape of a tailless hindwing to mimic the Byasa polyeuctes wingshape.

Interesting adam, i never really clicked with that thought of maraho not having true tails. Every true swallowtail remain with one single vein leading down the tail. Man, it really sounds like i haven't looked past the beauty and patterns haha. Either way, i guess its what makes maraho, elwesi, unique i guess. I love the shape of agehana maraho just as much as the pink/red color it displays. One thing i notice (now that i own one) that maraho on certain angles it can appear either deep red without direct light, while under light it appears quite pink.

another Taiwanese endemic, not as rare but getting there these days, horishanus female, bought a couple of weeks ago for the princely sum of £1, try getting one of these now, she does not look bad at all to say she has been in a newspaper envelope for nearly 60 years. Attachments:

Adam, the shape and structure of the whole body (incl. head and antennae) of Agehana and Chilasa is VERY similar to Pterourus (Pyrrhosticta)..,so I'm not surprised that was proved that they are closely related genetically . |

Thanos,
Thank you, I'm glad that someone else can see the physical similarities as well as read the DNA trees.
P. alexanor is the other Old World representative of the Pterourus group, although it split before Chilasa and Agenana. It still has Pterourus structures in the female genitalia, unlike the machaon group species which do not.
Adam.

Dave,
Byasa (nowadays, rather than Atrophaneura) febanus is actually a subspecies of B. impediens rather than a separate species.
