This is an awesome report! I think I waited half an hour for all the images to load.  I look forward to the day that I'm as skilled at finding larva and host plants as you (and others here) seem to be. Right now, it's largely a blind spot for me. |

WOW ! ! Skandinavisk, this article is no doubt THE finest, most informative, and comprehensive "personal account" of any birdwing species I know of. Your generous use of photographs is simply wonderful in conveying the thrill of seeing this glorious creature in it's native habitat. You were given the rare privilege of seeing all this firsthand; and you have documented it in a scientific manner for others to enjoy. What greater reward than the dissemination of knowledge through personal insight. Bravo dear sir.... Bravo.

Great Pictures, report and details, a really fascinating hands on experience, the best I have ever seen on a birdwing on any forum. Matsuka also visited Palawan to take images of the adults, larvae, pupae and foodplant and they appeared in his glorious book. Matsuka took his images of both sexes at Olaguan and Mount Salakot.

What a beautiful and interesting article !
Jan, if we can have such reports on every Palawan endemics you have met, it would be fantastic !
Have you met Delias singhapura yusukei for example ?

Nicely done indeed. From A to Z, on plant host plant -nice touch for Aristolachia- and all of that with great supporting pictures. Outstanding! Likewise, if you have extra material to put some more report such as this one: don't hesitate. CONGRATS again!

No it is perfect with all those pictures ! Thanks for your time !
Yes "mythical creature" is a good description for some singhapura ssp. Many collectors have tried to find them in vain.

Jan, have you run across any species in Palawan (on the wing, I suppose) that would appear to be Delias blanca? It's known from a range of subspecies in the Philippines and Borneo, but not from Palawan. I've long suspected that a subspecies remains to be discovered there; it would only make sense, given its known distribution. It's a rather rare species throughout its range.

No, there's also a subspecies in Borneo (which I've never seen).

It's on your website: nausicaa, described by Fruhstorfer in 1899!

Could Delias blanca have spread between Borneo and the main Philippine islands by the southern route, from eastern Borneo through what is now known as the Sulu Archipelago to Mindanao (the movement could have been in either direction), rather than via Palawan?

Could be.
But Delias blanca is known from Sabah (N. Borneo), not from Eastern Borneo.
I doubt that a big Delias would have been missed in a highly collected island like Palawan though, same for Eastern Borneo. If the locals find singhapura there, they would have found blanca too.

It has a patchy (known) distribution in the Philippines; Luzon, Bohol, Negros, and Mindanao each have a known subspecies. Only those from Luzon and Mindanao are generally available; the others seem to be considerable rarities in collections. I'm guessing that it may occur on other islands too, its rarity and lack of collecting on those islands being the reason that other populations haven't yet been discovered. It's true that Palawan is much better collected; perhaps it occurs only in a small pocket that hasn't been explored, which is my supposition for the lack of recent specimens of the Borneo subspecies. And the same situation for the several rare Delias species from Biak, not having been seen since the days of the Pratts, to my way of thinking.
