Note: The Philippine Postal Corporation will continue its Philippine butterflies definitive series with new stamps dated "2006" for use on international mails. Due to the increase imposed by the Universal Postal Union (UPU) on terminal dues, increase in special drawing right (SDR) conversion rate, increase in domestic cost and the imposition of the 12% value added tax (VAT), the international postage rates were increased effective March 6, 2006. All of the 12 stamps are modified version of the definitives issued in 2005. Each of the three blocks of four is denominated in the new rates to zones 1, 2 and 3 and they take on the butterflies each block is suppose to replace. Therefore the four P20.00 stamps featured the same butterflies that appeared on the P17.00 stamps; the four P24.00 stamps show the butterflies from the P21.00 stamps; and the four P26.00 stamps depict the butterflies featured on the P22.00 stamps before.

20p Idea electra electra (Semper, 1878).  A unique species confined to Mindanao. Popularly known as the "Dragonfly Idea" due to the appearance of the males' elongated forewings and extra long abdomen.

20p Charaxes bajula adoracion (Schroeder & Treadaway, 1982). Uncommon nymphalid species found in Northern and Central Luzon. The butterfly was named after writer Adoracion Gaskell Nuyda for her contributions on pro-environment articles.

20p Tanaecia calliphorus calliphorus (Felder, 1864). Inhabits forested undergrowth areas and can be found in Luzon, Marinduque and Polilio Island. Can easily be recognized by the iridiscent blue band on its wings.

20p Trogonoptera (Honrath, 1886). This butterfly is an endemic species in Palawan, where it replaces Trogonoptera brookiana in the rest of Sundaland. Trogonoptera trojana is considered one of the most beautiful oriental butterflies.


26p Parantica noeli.  One of the most significant finds of the decade, this new species is one of the most striking Danaid butterflies.

26p Chilasa osmana osmana. An extremely rare swallowtail from Southern Leyte and North-eastern Mindanao in the Southern Philippines. A relatively large tailless butterfly belonging to the veiouis species-group.

26p Graphlum sandawanum joreli. The Apo Swallowtail (Graphium sandawanum) is a species of butterfly in the Papilionidae family. It is endemic to the Philippines. This butterfly can be found at high altitude on Mt. Kitanlad in Bukidnon.

24p Cethosia biblis barangingi (Tsukafa, 1985). Inhabits southernmost Philippines: Bongao, Sibutu, Tawi-Tawi and Jolo. The intense bright red-orange color of the wings in flight makes this species one of the most attractive butterflies. 

24p Menalaides polytes ledebouria (Escsholtz, 1821). Common once upon a time but now uncommon perhaps due to progress. The butterfly can be seen all year round and is distributed throughout the archipelago. Can be found around human habitations and also thrives in secondary forests.
24p Appian Hero palawanica (Staudinger, 1889). A popular orange pierid butterfly distributed in the Chinese peninsula to Sundaland and the Philippines. Subspecies A. n. palawanica can be found in Palawan. The female has three forms- orange, yellow and white distal band on its wings.
