Graphium stratocles is mentioned abundantly on the Internet, and most of those mentions come from sites that traffic in butterfly carcasses. This web site does not recommend paying for dead butterflies.
There are three subspecies: Graphium stratocles stratocles, G.s. senectus, and G.s. stratonices. All were named early enough to be part of the tradition of naming Swallowtails after characters in literature. Stratocles was the name of two ancient Greek politicians. Stratonices is a masculine form of Stratonice or Stratonica, a Greek queen of Syria. (She was remembered for having married King Seleucus, who was older than she, and getting him to divorce her and let her marry his son instead after she had met the son, Antiochus.) Senectus was the Roman spirit of Old Age, a gloomy mythological figure said to hang around graves--the Graphiums are not notoriously attracted to carrion, but male Swallowtails do crave salt. More recent sources also list subspecies dodongi and pingi, as described by Page and Treadaway only in the present century.
Each subspecies is associated with some of the "thousand islands":
Graphium stratocles dodongi is found on Palawan.
G.s. pingi is found on Busuanga.
G.s. senectus is found on Luzon and Marinduque.
G.s. stratocles is found on Mindoro.
G.s. stratonices is found on Bohol, Dinagat, Leyte, Mindanao, Panaon, and Samar.
None of these subspecies seems to be uncommon or particularly endangered in its habitat. Photographs are scarce online, perhaps because this species mimics the look of some other butterflies who share its habitat, whose wing structure is quite different.
Santibiologist, who posted this photo to Inaturalist, spent some time confirming its identity with other lepidopterists.
There is little discussion, but a nice clear photo of the upper wings, of this species in
Perhaps because other butterflies in the area are even more eye-catching, little is known about this species. From the fact that Rothschild claimed to have female carcasses and didn't describe any differences between them and the males, I infer that the wings of both sexes look alike. Rothschild also found the species so rare on Mindanao, in the 1890s, that he questioned whether reports of their being found on that island were accurate.
