Papilio chikae is endemic to the Philippines and it is listed on appendix 1 of the CITES. Papilio chikae seem to have become extinct from one of its first known localities, Mount Santo Tomas (approx. 2200 m.), Benguet province, which is just S-SW of Baguio City. The area around Baguio City has been ravaged by real estate development and mining activities for many years and obviously this is not going to change in the future, with great commercial interests. However, Papilio chikae seem to be much more widespread than commonly assumed. At suitably high mountains in the Cordillera Autonomous Region (CAR), this gorgeous butterfly is still as common as it always was in its natural, forested habitats. Thierry Heitzmann has posted some great pictures in another thread on this forum (here), that show the typical habitat of Papilio chikae. The CAR region receives 2500-4000 mm. of rain annually and clouds and rainy weather sure test ones patience looking for Papilio chikae, even during the "dry season". Males are fund of puddling on mountain roads on sunny days and this is the best chance to see it in the generally very steep mountains.
